300's Compared 

Great discussion!! I HAVE BEEN USING THE 300WIN mag for 30 years with no issues whatsoever.

Great stuff Randy, my 300 Win Mag works for me. God bless.

great info.... a true craftsman. You can't get no better than this. Any other source can't hold a candle to Randy. Every video is more and more compelling to enrich the sport more and more ! Than you Randy And God Bless

Thank you Randy, we are loosing this valuable knowledge. You should write a book my friend. Thank you Cathy, as always top camera work.Kind regards and God Bless from Australia.

Thank you, Randy. They are all good choices. I am partial to the 30 Nosler, have shot a friend's, and hope to be building one soon. I have another friend with a 30-378 Weatherby and you couldn't buy his, twice the price. It's a freight train!

I was gifted a Winchester Model 70 Pre-64 300 H&H Mag and what I know is a Nosler AB 180gr Bullet going over 3000 FPS will do anything I need to do in North America as a Black Bear found out this spring.

Randy, again thank you for your knowledge. As you know, for me at least the .300 Weatherby Magnum will always get it done!

Thanks Randy and Kathy for sharing your valuable information with us. God bless both of you as he has us with y'all!

Randy, I have been hunting and reloading for over 43 years and want to thank you for your informative videos. I also agree with you about not buying into all these new hype cartridges when the older ones are fine

Long live the 300 RUM. I remember when Remington released it with power levels 1,2 and 3. It was 30-06 level, 300 win mag and full house and I thought it was a good idea but nobody does it that way now.

Thanks, Randy, your decades of knowledge are a gift to all of us, thanks for your generosity and for sharing with us, you and your wonderful wife are the best. Cathy is your rock.

That was very well presented! Very good information to have ! The different powders were covered very well !

You have very sound and practical experience and advice, love your videos and channel!

THANK You Randy for all your skills and knowledge and sharing!! I am a 300 win mag shooter for 40 years.

I like the original 300 magnum, the 300 H&H.

I've had most of these over the years 30-378, 300RUM, 300 Weatherby, 300win mag, 300WSM. These days it's very costly to get good bullets and impossible to find 338cal and 375cal at present. For this reason I've found 270win 308win and 30-06 to be available and at least components easier to find so that's what I'm using. I realize my 270win isn't an 300 Weatherby but at least I can buy ammo and cases to reload for it pretty easy.

While the case capacities are similair between the 300winmag and the 300PRC, the PRC has 1000PSI more working pressure under SAAMI and because the bullets are seated further out of the case, heavy bullets don't eat up eating case capacity. We're able to see about 10% improvements in velocities between the 300wm and 300PRC and that's significant.

Been a 300 Weatherby guys for years have 7 Weatherby too both fine rifles , there are 2 types of Weatherby owners those that own and those that dont

Thank you for sharing your test results.

Amazing encyclopedia of gun knowledge, thank you.

300 WSM

The 300 Weatherby is a timeless classic! Some shy away from it due to cost. The RUM does not really beat it. The difference of 50 to 75 fps is not a real advantage in the field. Stuffing more powder into a slightly larger case also pushes barrel life to a point where practicality is a question. I have found considerable differences in performance between the Weatherby and Winchester. My chronograph testing has shown over 100 fps advantage with numerous weights when compared to Winchester 300. I’ve recorded 3095 fps with 200 grain round in the Weatherby. Accuracy was superb. All in all the 300 mag, for whatever version you pick are fantastic performers.

Randy, thanks for your opinion. I'm a gunsmith also, and I think the advantages of the 300 PRC are that it does not have a belt like the standard magnums which can help accuracy and it allows heavy for caliber bullets and longer cartridge OAL so there is an advantage over the 300 win mag in that regard. Is it a huge difference? Not really, but why not take all the advantage that you can get with everything else being equal. Also, a lot of my customers don't reload, and the other advantage to the 300 PRC is the cost of ammo vs the larger capacity magnums. Thanks again for these videos.

I have loaded/shot/hunted with the Nosler Accubonds for quite a few years with great results. Unfortunately, I have not been able to purchase any 7mm AB’s in quite some time. Very disappointed with Nosler and made the switch to Hammer Bullets. Great support, easy load development, and readily available. Enjoy listening to you Randy.

I’d read and cruised through forums for about 6 months trying to decide what to get as a magnum rifle. I live in the Southern US where I can take every larger game animal with .30-06 or .308win, and have for 30 years or so. Decided I wanted to go out west in the future, so I went initially with a .300win mag in a Savage rifle. Shortly thereafter, a friend decided to sell his new Savage chassis style rifle in .338 lapua mag, so I picked it up as well. I’ve shot the .300 quite a bit and love it, the .338 is ridiculously expensive but shoots well also. Thanks for the experience with the bullet types and manufacturers, I’ll definitely be taking advantage of the info! Thanks sir!

Really enjoyed your comparison

Very interesting words of wisdom. I enjoyed this. It would have been fun to hear you throw the 300 H&H in there. It's my favorite 300. Most efficient, Less recoil and shoots the same velocity with 180 Accubonds out of 26'' barrels. I have all the 300s except the PRC and the RUM. Love the old 1920's 300 H&H. Great video sir.

A true professional my hats off to you thank you

Thanks Cathy for your videos with your husband. Right now the prices of 300WM is still the best and casing with 338 Norma is going down with it becoming a new military cartridge, looking on ammoseek

Great video and info. Looking forward to a possible 7mm prc video.

Hey buddy I’ve never meet you before or had the pleasure of talking to you in person but I do enjoy your videos and knowledge about guns and ammo keep it up! Best regards Weston Baird

Great, honest video. Thank you

I have a . 338 RUM and the thing just Loves Retumbo with a 250 grain bullet. I also had a couple really nice pet loads with NABLR, but good luck finding them. I even emailed Nosler and they very politely and professionally told me sorry for your luck. What a shame.

Great video Randy. Good common sense advice on cartridge, bullet, powder and primer interaction. I'm assuming the Win and PRC numbers were in 26" barrels. Personally I have found success with all my 300s (Win, RUM and Weatherby). Recently I've become enamored with the 2nd oldest 300. Not the H&H, but the 300 Savage. I know it's small, old, slow and weak compared to the Magnums, but I really dig the old 99s. Next time I'm in your neck of the woods, I'm going to look you up. All the best to you and your bride for a healthy, happy, prosperous, blessed 2023. Cheers, Jeff.

300 prc. Modernized 300 win mag. Saami spec’d to stabalize the longer higher B.C. bullets that manufactures have come out with. For getting a custom rifle, as Randy does, pick you poison. In the box store rifles, from the ground up the 300 prc is designed for greater consistency out of the box. But, we all know that the out of the box qualities doesn’t make a better shooter, it’s time behind your rifle building confidence to take into the field.

This guy is an excellent teacher.

🤠 Very good discussion and I can wait to hear more! That being said, I used to have some Bigger 30's, one of which was the Lazzeroni Warbird! It's case water capacity was 130 grains, while the 30-378 Weatherby is 133 grains of water! However, the pressure rating for the Lazzeroni Warbird was 66,000 psi, while the 30-378 Weatherby was roughly 63,000 psi! That difference in pressure, 3,000 psi, enabled the Lazzeroni to push a 180 grain bullet roughly 150 ft/s faster! However, I had to back off on the velocities 150 ft/s just to get it to shoot! It was rated to push out a 180 grain bullet at 3,600 ft/s and a 200 grain bullet at 3,350 ft/s, but backed it down to 3,200 ft/s for my 200 grain Swift A-Frames! So, it somewhat defeated the purpose of getting it in the first place! If I were to buy another 30 caliber (though my 30-06 has served me well), I would choose old Roy's 300 Weatherby Magnum! I have shot and seen game shot with my uncles and friends, 300 Winchester Magnum, 300 Weatherby Magnum,, 338 Winchester Magnum, my 338 Lapua Magnum, and Uncles 340 Weatherby Magnum! To me, the 300 Weatherby Magnum is enough gun, without overkill! I had 3 butchers in the family and they all hated Magnums, due to excessive meat wastet! After 45 years of hunting, I now understand their position! However, you touched on another Very Important Point - Bullet Construction and Selection! This subject is sadly overlooked by too many people and I'm really glad that you brought it up! Thanks again and Keep up the Good Work! 👍🙋‍♂️

Thank you again randy for taking time out of your days to to share your expert thoughts and knowledge. I Would love to hear Randy's thought about the 300 norma mag maybe one day on the future

Three cheers for WC860! I have used it in the .378 Weatherby.

I bught my first 300 this year, I went with the 300PRC with 1/8 twist. topped it with a VX6 HD 3-18x44

About 35 years ago I purchased a bolt action in .300 Win Mag. It's made by Krico, a now defunct company from (the then) West Germany. It's been a tack driver straight out of the box. On one excellent day, I got a one half inch group at 200 yards. That's quarter minute of accuracy. Not bad for an off the shelf rifle. With a hand load I worked up, I'm getting 3,000 fps with a 180 gr. bullet out of a 24 in. barrel. That's plenty enough velocity (and energy) for me. Recoil is stout but manageable. I understand that greater velocity means more energy but if you've got enough, why chase more? I don't do long range shots at game. My solution to a 700 yard shot is to get 500 yards closer. I do some long range shooting at my local range where it goes out to 1,000 yards but to me, hunting and target shooting are two different things. Having an excellent 30 calibre magnum rifle in my .300 Win Mag, I don't see the need for a Weatherby, a .300 PRC or whatever. If I was just starting out, I'd look around... and likely choose the .300 Win Mag. It's enough gun for elk, moose and bears. It's an excellent cartridge for the mountains. If you have to 'reach out', it can do it. (But try to get closer!)

Simply Great beyond this ordinary world

Figured out impact of freebore in the 1980’s while working for Bull Wiseman in the 1980’s. I first did this with a 264 Win Mag. Great video. However, if you use some of the newer Powders in a 300 Weatherby Magnum you can hit 3,300 with a 180 Nosler Accubond within pressure designs. Also, grove depth and width impact velocities as well. Rifle barrel has to be able to relieve pressure.

Irregardless is a word - thank you for educating me on that point.

For me, not being a handloader or one to buy custom rifles, if I’m buying a new full magnum 30, it has to be the PRC for the heavier bullet capabilities from the factory. However, in the end I would probably go a hair lighter than all of these and run the wsm with a copper alloy 165 grain and forget about running heavies.

I wish I knew half of what you have forgotten over the years Randy sir. Great video to y’all be safe and GOD BLESS

One can not go too far astray using the 30 magnums for game. I purchased my 300 Weatherby almost by chance, and found it to be a solid performer. Just last month a friend and I re-chambered a 30-06 barrel to 300 Winchester Magnum to replace a bad 7 Remington magnum barrel on a Vanguard. We are both experienced elk hunters, using 7mm rounds, and also many larger rounds. But, in the end it is hard to beat a 300.

This old boy SHOULD remember when someone said 300. There was ONLY 1 "300", THE 300 SAVAGE.

It would be so interesting to be able to spend time talking to randy

The only advantage to the PRCs is an off the shelf rifle capable if shooting heavy for calibre bullets. If you go custom the older cartridges are as good or sometimes better.

Sure the .300 win mag and PRC are close at those low weights.. but that is taking the PRC away from what it was designed for. It was designed to fire heavy for caliber bullets. Hornady has a great story on how and why it came to be from custom built .300win mags that were made to accept rounds much longer than SAMMI specs and use short twist rates. Many people only ever look at the 500yrd data and say there is no reason for the PRC to exist... however, if you look at the 1,500yrd data, it is a completely different story. For me personally, I do 90% of my hunting with .308win. I use .300PRC for sport shooting (1,000yrd). If I need something for some longer range hunting (elk/moose/mule), then I have my .338 Lapua which will get the job done on anything in North America.

We are listening and we will continue to listen to everything you have to say until the day you don't. I can only imagine the library of knowledge you have written down

The 180 Accubond is an awesome Elk/large deer projectile. Works wery well in my 300WM, and equally in my 300RUM, which really tests a bullets ability to hold together.

Great video Randy. In my testing, I have found nearly identical results to yours. I tested the 210 Long Range Accubond in a 300 Ultra, 300 Wby and 300 Win. All with 26" barrels and similar throats. It didn't matter how many different powders, primers, etc I tested with each of these cartridges. With a 210 LRAB, and a 26" barrel, ALL 3 cartridges pressured out at 4300 ftlbs of energy/3040fps at the muzzle. There was ZERO advantage for the 300WBY and 300 Ultra, over the 300 Win in 26" barrels. I am convinced the barrel needs to be longer to see ANY appreciable difference between those 3 cases. My buddy is a gunsmith and he found the exact same thing to be true in his own testing but with 180gr bullets. Another buddy just built a 300PRC, we will be testing that shortly. I assume we will find the same thing, 4300 ftlbs. Thank you for spreading the TRUTH! The case size doesn't matter unless the barrel length is there to use it.

Couple years ago I wanted to add a 30 cal magnum to my collection. Was going between the 300WM and PRC. I chose the PRC mainly due to the fact the design is just how the industry is shifting towards. Figured might as well get this. But had I already owned a 300 WM then I wouldn’t even consider a PRC. Not enough difference between them to buy a 2nd gun.

Randy my first hunting rifle was and is Tikka t3x lite in 300 winmag. Since I have 1 in 11 twist I use 168 ttsx. And 190 accubonds. My barrel is now 20 inches and i put asr 3 port break. Im 6'5 so that extra 4 inches wasn't fun

Mine 300 blk 200 yrds, 30'06 800 yrds and 300 prc 1500 yrds. Mix and match bullets between all depending on use ie defense, hunting or punching paper. Everybody is different, every need is different. There are no right or wrong choices. Just choices which is the best part.

You mentioned measuring the case head expansion to determine case preassure. I would like to hear more of your thoughts on this. I have read conflicting advice in reloading manuals and gun magazines on this subject. The conflicting information is some say you must use new brass while others say you must use once fired brass. On paper their reasoning for each method seem valid. What do you do and why?

Ive found a load that I have never veered from that shoots half inch groups all day long with my 300 RUM. 180 grain Swift A Frame with 100.5 grains of Retumbo Powder. I seat .023 off of jamb point and bump the shoulders .002”. Never felt the need to increase weight or use a Long Range bullet with high BC.

Win mag. Love it. Rum is sweet but if I need more. I’ll just move up. Lapua AI I use the 180 AB. At 150 key hole. Still working on the 190.

The 300 Norma Magnum seems to have the best BC in the heavy bullet. The military has just selected it for a sniper round.

300 Rum. I built one for king of one mile 33” barrel and it pushes the 245 Berger bullets at 3140 FPS my Chamber is 4.150” and I seat at 4.125” and it’s a hammer only factory case that beats it is the 30-378

Hi, Randy. Hope all is well with you and the missus. I’m wondering what length barrels your using on these rifle builds; 24”, 26”?

Thanks for the info Randy How far off the lands do you run the 180 accubonds in the 300 rum?

Have you built and tested any wsm rifles, like the 7mmwsm, 300wsm or the 325 wsm?

We build a lot of 30 Noslers with 210g Bergers. Q.M.M.

.30 caliber, America’s sweetheart

Good stuff Mr. Randy, an extreme long range shooter out of Australia actually found that the old win mag outperforms the prc in the high bullet weights

again, thank you!

Hard to beat a 24 to 26 inch barrel on a 270, 280 or 3006 hand loads. If twist was spread up to 1 in 8.5 new cartridges are not needed.

Living legend!

Thank you

I just enjoy the 30 caliber. Got a long range shooter in 300prc and 308, a hunting rifle in 300 win mag and 300prc

I believe I will stick with my idea since I was 20. If I need a 300 I will just use my 338wm.

The PRC would excel at the 225-245gr VLD, high BC bullets

Savage 300 and 300 H&H. Throw in a 12ga and a .22 and you have all the guns you need.

Randy is the absolute best there is IMHO.

Everytime I watch your videos, I never know your name so I write santa next to each idea you give me.

What are your thoughts on Reloder 23? I believe it is supposed to be a more temperature stable version of Reloder 22.

I feel like with magnums, the Win Mag/PRC/RUM replicate the dynamic of the 308, - 06 and Win Mag. It's a couple hundred fps difference, a little untapped potential in all of them, and have strengths in different niche sports.

300 wsm would be great one to hear..

Thank you..

Hi Randy what lead free bullets do you recommen for the 300 weatherby Magnum. We're I live they only allow lead free bullets for hunting Thanks .

Any 30 cal cartridge that can throw a 200 grain bullet at 3000 fps or better is just plain awesome. Elk, Moose, and all African plains game and the largest mountain rams will be flatten with a hit in the vitals. Elgin Gates proved that with a 300 Weatherby long time .

300 prc wins it for me. Modern case and chamber design made long range shooting from the get go.

Hi and wow. Is your .0005 case expansion rule generally followed by other hand loaders? Or do many? other handloaders like a different amount of expansion?

AMEN ! PRAISE THE LORD AND AS ALWAYS WITH YOU RANDY ! BINGO BINGO BINGO !

The 300 H&H is still king. It ruled 1000 yrd prone match shooting from 1925 through the early 60's. Some of the best targets shot back then compare quite well with what is shot today. Not only that a M70 can get 4 0f them in the magazine, one more that the 300 Win Mag. It is the most efficient of the lot to if you compare bullet velocity vrs. grains of powder. To top it all off you can feed those empty 300 H&H brass through the action like butter. You don't really notice the bolt working stiffly as you chamber a round. Try that with any other 300 Magnum...

I can't believe there is no mention of the .300 Savage. I feed the family really good with a Model 99. The best part is l don't throw a lot of blood shot meat away.

Just letting you know, your website is not coming up on google or Microsoft. Great show.

I just found your channel. Do you or anyone else here have any experience with using berger combat/target bullets? Thanks for the video 👍

Thanks Randy! How about the Terminal Ascent Bullets?

I haven’t had a problem with my 300wsm

300 Norma Mag??

The 300 Win Mag is coming up to it's 60th anniversary next year & the 300 Weatherby it's 80th the year after. Randy, I don't mind saying that there's room enough & time since gone enough, for a new & improved generation of cartridges with more efficient case dimensions & more closely matching chamber & cartridge dimensions than those old designs. I don't believe either of those older designs are going anywhere soon but, surely the addition of some new & improved stable mates couldn't hurt.

Curious if anyone has experience with 7x65R loads. Looking for data, 175gr for 1:8.5 twist Sauer & Sohn German drilling. Already purchased Hornady 175gr Eldx bullets. Wasn't aware that they tend too come apart too violently. Iron sight appears to be on at 100yds with 175gr bullets.

In the three hundreds I like the 200 grain Speer hot core spitzer. Randy, have you tried it?

If you want to buy an off the shelf rifle. Not pay to have a deeper cut throat on a cartridge to allow longer COAL And shoot 200+ grain projectiles. 300prc is the cartridge. 300wm/wby/rum with 200gr bullets start eating case capacity. Once you get to 220gr-230gr the PRC is the obvious winner If you want 190gr or less projectiles, those other cartridges become more advantageous.

I have the 300 prc and want another 300. Can’t decide between the 300 wm or 300 wby. Any help lol

Accuracy and repeatability, thats all that matters. That being said 300PRC with a super accurate barrel wins.
