7mm Rem Mag vs .300 Win Mag Barnes LRX Chronograph 

Two of the best big game cartridges in the world. You can't go wrong with either one. Let's Go!

Thanks for the video! I enjoyed seeing the two "do everything " rifles compared! Have fun, good luck, don't let that rainy weather get you down!

Great looking loads. I’ve always been partial to the .300 WinMag.

Appreciate the great bullet selection & real life #s for data. Both are simply excellent options for anything & everything in North America. I chose 7 mag back in the mid 80s as my choice for magnum rifle. I have no regrets. Many family and friends have great reasons for choosing the 300 Win Mag & a few opted for the 300 Weatherby. Your 7 results are pretty optimal IMO. You might pick up another 40-50 without problems using a bit slower magnum powder. We rarely get 3000fps out of our 180 handloads using a variety of magnum powders & 24" barrels. I think you have a better 300 load here than you think. Thanks again for great content. Enjoy.

I've been waiting for this one!!

Everything you hunt in Alaska will be hurting if hit by either.

Thank your for the specification in m/s and Joules👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Good video. 🎥🎬 Thank you!

Have a 7mm Rem Mag. Considered a 300 WM but never pulled the trigger. Good comp Chuck.

Excellent comparison. Totally agree with you on the sectional density. Be nice to see a penetration test.

Hey Chuck, great video thanks. I am slightly more in favour of 7MM mag than 300 mag due to ease of getting a good BC with the former. However both excellent calibres and hard to beat. Although a 7MM fan my favourite rifle is a 3006AI which is close to what your 300 mag did in velocity. In bear country I would rather have the 300. Both awesome calibres and I personally believe they are both ideal ‘one cartridge’ calibres for hunting in New Zealand. God Bless Dave

Just noticed that you give ballistic results in metric, that's great !! Your channel deserves going international just don't tell those French guys where you get the cooking pans in Alaska with the shortage ... if you get my drift.

Thanks for sharing

Hell brother, it’s still raining. Going on 5 weeks now. Maybe 6, I forgot the last time we had the big yellow dot in the sky. Hahaha. 😎🤙

My shoulder loves the 7 mm magnum.Both are great

Both are excellent cartridges. I own one of each, but they see limited action these days. My .300 Weatherby, .340 Weatherby, and .28 Nosler are usually on first call when it comes to hunting out west. They'll probably get called up when I finalize my African plains game hunt next year as well. Last time I used my 7 Mag was ten years ago. Took two Texas whitetails with it. The .300 Win Mag last saw action about eight years ago in Wyoming, on a successful mule deer hunt. Incidentally, Bergara offers some well made, accurate rifles, and usually at a very price friendly waypoint, for the average Joe DeerTag. I handload the 7 Mag with 140 grain Nosler Ballistic Tips atop Reloader 19. For the .300 Win Mag, I shoot 180 grain Nosler AccuBond bullets over H1000. Both are spot-on, point-of-aim accurate, and the game always drops where it stood. I just prefer the extra velocity I can safely coax out of the Weatherby cartridges, while gaining flatter shot trajectories, and maintaining consistent accuracy. That .28 Nosler is a waaaay downrange bolt of lightning! I stoke it with 168 grain Nosler AccuBond LR bullets and Retumbo magnum powder. It's going with me to Wyoming and Colorado next month, along with my .340. Funny thing, when hunting the Midwest, all I ever use is my Remington 7400 semi-auto .30-06., see-thru scope mounts, with open iron sights, and a 3x9 fixed Redfield scope. Never shot one past seventy-five yards here at home. Most were like about twenty-five to fifty.

Really interesting comparison , with Great Proven details...Between these two cals , The question of whats better will always come down to personal QUIRKS , NOT even opinions.Great show. I target shoot both,, Hunt with 3006 ..

Love my 7mm Rem Mag

I am pretty biased towards the 7mm's. I own a 7mm Rem Mag, 280AI, 7 SAUM, and not to long ago I added the 28 Nosler. I'll probably have a 7mm PRC built once things start coming out for them to add to the arsenal. I really like tinkering with different cartridges and when it comes to the 6mm's, 6.5mm's, and 7mm's I have a really good selection just because I can do everything from long range plinking, compete, and comfortably hunt everything on this continent. That said if all I did was hunt big brown bears, shoot out past say 1500ish yards or maybe did the Africa hunting thing I'd have something bigger but other then an old 30-30 and 30-06 I inherited I don't use or own anything bigger then a 7mm.

Good video!! I just purchased 2 7mags recently!! Gotta try to round up some stuff to load with. For now I’m stuck with 50 dollar a box mass produced ammo. I’m excited to see what these guns do.

Great job comparing bullets with similar "form factors" where the sectional density is the common denominator. Well done Chuck !! As far as speeds are concerned, as much as I like and use Reloader 22, it isn't the one yielding the fastest speed in the 300 Win Mag. Try Reloader 17, and at the other end of the spectrum , Reloader 26. With your longer barrel, you'll get close to 3100 fps and more, you may match the speed of the 145 grain LRX in the 7 Rem Mag. Rel 17 gave me good results with close to a maximum load for the 168 grains TTSX. a bit above 3220 fps with excellent S.D, less than 10 fps consistently and good groups ! With that combination on two separate occasions... I haven't tried the 175 LRX yet. With Hornady's 165 grains GMX (not CX) using Reloader 17, I got off the chart speeds but big discrepancy in S.D. and the groups were not good while the Superformance loaded rounds from Hornady with that particular bullet gave exceptional speed and accuracy. I'd try the Barnes bullets with that powder.

Great video like the weatherby rifle I got one in 257 wby try some reloader 25 in the 300 should be able to get mid 3100s barnes data from there book is little on the light side but work your way up be safe

Thank you for this very informative video. I've been all about the .30 cals for many years. But have acquired an appreciation for the 7mm's in the last 3 years or so. I like both but I like the 7mmRm just a wee bit more. Just wondering... have you ever tried 9.3X62 Mauser? I'd like to see you do a video on that caliber. Including testing penetration. I think it would be a great caliber for Alaska. Kind of like a .35 Whelen but .366 and with a bit more punch. I've looked around online and haven't seen any ballistic gel tests or tests with pork ribs and water jugs with the 9.3X62 with a 286grn bullet. I'd be very interested in the results of either.

I would like to try some copper bullets but most of my shots are under 150 so they worry me if they are going to expand at close ranges! Great vid!

Love the 7mm great gun . 300 will be my next buy.

I love the 7mm mag ! Realy like to get another one here soon. Got family member that swear by the 300 win mag with prlenty of big pa whitetale and big candian black bear to not give 👍 to big .30cal on game.

Would you recommend this chronograph? I’m trying to see how hot my browning 7mm with a 26 inch barrel shoots factory ammo since they often give you the results from 24 inch ones

7mm Rem was my first rifle in 1973 and still have it,hard to separate me and my 7,shot most everything else,but Creedmoore,still favor my 7s

Hunted with a 7 mm mag for nearly 30 years resently got a 300 win mag model 70 , the 300 a different Creature , more shock power at long range love both later stronger !

I’m a .284 fan so I’m going to go with the 7mm rem mag.

I think 170 grain and 200 grain bullets respectively take a good bit more advantage of the cartridges potential. Going lighter with magnum cartridges has such diminishing returns in velocity. The actual energy and especially momentum at the muzzle (not to mention lower BC) with middle weight bullets no longer seems like a proper magnum but closer a hot .270 and 30-06. Good test though.

Just curious as to where you're shooting at. Just moved back to Alaska after a 16 year absence and need to get the boom sticks out...

Chuck, what stock do you have on the 700 Rem? I’ve been looking for a Remington 700 in 7mm Rem Mag.

My 7 mags are easy to shoot, my 300 was not. Only 10% difference in energy, flatter trajectory and not much difference in tissue damage. Happy with 7 Rem

I have both of these. Honestly for deer hunting, I like the 7mm better. For anything bigger, probably the 300 just for the extra bullet weight. 7mm will kill anything on north American continent though. I have an old (1963) remington 700 with a shot out 7mm barrel. I'm thinking of having it chambered in 7mm/300 wm for the best of both worlds.

I own and love both. So this is a tough call. So, with that said, if I could only have 2 hunting rifles. The trusty ol 300 Win Mag & the 7MM Rem Mag for the win.

A good comparison would be matching cases. Either Winchester Short Mag or Remington Ultra Mag. Hard to do because of how difficult it is to find rifles in 7mm RUM. I would have thought the 300 case capacity would have given you better velocity. Still a good comparison. Don't think very many critters could tell the difference out to about 500 yards.

I like the 7mm magnum as it wins sectional density with acceptable recoil impulse.

I have a 300 win mag with a muzzle brake, recoil is like a .243 with 300 win mag hitting power.

if your powder is temperature sensitive, then your velocity will go up a lot as the chamber heats up. Theres only a few that are truly stable h4350 and vv555

You should also check out 200 gr lrx. They work perfect on moose.

Neither is good here we have killer jurassic chipmunks

Enjoyed the video. Honestly think a 300 Win Mag is wasted on 175 to 180 grain cartridges. I load 208 and 225 in an 8-twist 30" barrel with a match chamber with 0.164" free-bore. I load them long, with a COAL of 3.640" which allows for more power than loading them at the 3.340" COAL. I'm getting 3,074 fps with the 208gr and 2875 fps with the 225gr. Both are excellent 1-mile steel-bangers. Shooting 175s in a 300 Win Mag strikes me the same as shooting 110s in a 7mm Win Mag...Sure you can do it, but why? Maybe the hunting application is totally different than long range target application.

Shooting the 175 LRX in 300wsm. Getting it to 3150 fps using superformance powder and single digit SDs

My first gun purchase was a Remington 710 chambered in 7MM Rem Mag. I was shooting 150, 175 and 180 grain boolats.

I’d be curious the difference between totally cold bore and not.

Lighter bullets will travel faster than heavier bullets do if you had loaded up 175 grain bullets in the 7mm mag it would be closer to the velocity of the 300 mag bullets

I came for the penetration test comparison...

I love my 300 win mag kick like bull but love it 🔥🔥🔥🔥🔥🔥💪💪💯

For me, between these 2 calibers, the 300 Win gets the nod all day long

7mm Rem Mag is my preference.

Barnes LRX or TTSX work fantastic!!!!

The 145gr. is hard to beat.

I’m getting 3260 fps with MagPro powder on my 7mm. 26” barrel. 150 grain TTSX

I have long been biased against 7mm Rem Mag. Over promoted and under performing in so many combos of factory rifles and ammo. Custom and full 26" barrels and handloads can change it to what most people think it always was. Performance doesn't just happen. You have to make the effort and see to it that it happens.

From Russia with love Chuck ))

You can get a lot more seep out of both of them using mag and magpro prowder

👍👍

Is it possible that your first shot in the 7mm mag was in an oiled barrel? That would diminish the speed.

But witch is better than the other?????

I tested my FM-9 , 16" 9mm , in a nut shell it adds about 200 FPS to a 4" Ruger Sam tested on most rounds , some were the same lot # he tested . Gold Dot 124 gr +P was the best +P round >> 1,400 + fps . SIG 124 gr JHP was the best non +P >> 1,350 FPS . 115 gr FMJ Fed & Win wt box JHP both got >> 1,315 FPS . RE Ranger +P+ 127 , only 25 fps faster than gold dot , the primer looked a lot flatter , I would only use it in winter for a rifle , Never a handgun .

Hope u bought the brass a while back! Nosler has lost my business. Although, I believe these two calibers are the best two out there. The 7mm just barely win in my book.

I wanted a 7mm rem mag vs .300 win mag comparison and specifically looked for your channel cause I wanted to skip all the bullshit lol

Im getting about 3075-3100fps with 165 Barnes out of a 26" 300 WinMag and h4831 Short cut.

I had an early SS rem 700 24" 7 mag, liked it, bot my pretty wife a 270 (22") to have a kinda matching long range rifle. Oehler 33... 7 mag 160's - 3000 f/s Dont remember, 4831 or RL 22. 270 130's also 3000f/s, same powders. Hmmm... only 30 grains difference, 2.5 lb lighter rifle, 2" shorter, way less recoil... Nosler partitions - any REAL difference? Sold the 7 Mag. I did later come by a new 700 in 300 WM... 180's - 3000 - 3050 f/s. Now GO FIGURE THIS! I consistently got Better pressure /velocities with 4350 in the 300, while my 30-06 got the same with Norma 205. I could not make 2700 with any other powder in my '06, 205 consistently gives me 2730. Not max, either! Counter intuitive, eh? I also do better with 4350 and 200 gr partitions in that 300 WM. Case geometry? The gun? Work up some loads with H4350 (temp stable) and play around. Proven results over the screens. Jerry

I have to admit,I am disappointed in the 300. 2960's is factory advertised velocities for 180.

I'm pissed that only the 190 grain is avaliable in factory ammo. Only runs 2840. They need to load that 175 in factory 300winmag.

👌🇺🇸

First one was cold barrel I believe

Both great calibers, but as someone who owns a 300 win mag, a 30-06 and a 270 win, I don't think I'll pick up a 7mm anytime soon. Not worth splitting the difference in my opinion. Don't hunt anything larger than black bears and whitetail anyway. That 300 definitely could have been pushed faster. My 26 inch 300 pushes 208gr bullets at 2850 or so, and 165s at 3200.

It's not either or, this is America, buy both!!!

In Alaska id feel safer with the 300wm for hunting.

I really think cold bore shots are slower

I reload a 175gr bullet for my 7mm.

Chris Kyle swore by 300 win mag. I'm no navy seal, but if 300 win mag was his preferred choice that should say something.

I guess most Girls out there would prefer the 7mm.😋

300 win all the way

As usual the 300 beat the crap out of the 7mm

Have both seam's to me 300 mag a different Creature in my eyes , saying that both deadly choices ! Sorry

I guess I'm an iDio+. Sectional density is the most BS waste of time POS term still used in hunting. Sectional density is the weight of a stationary bullet divided by its cross sectional area before it expands. I've never killed a deer with a stationary bullet that didn't expand! It has absolutely ZERO effect on game or terminal performance. It can be correlated to BC but nothing else. A monolithic bullet with the same SD as a lead bullet will perform drastically differently and both will depend on their velocity. The rest of the video is great! My suggestion to you is when using monolithic bullets, drop the weights by 20% +/- because they maintain their weights so well after impact they don't need to be heavy. So try a 110 gr TTSX or LR-X in the 7mm and maybe 130 gr TTSX or LR-X in the 30 cal. The speeds will go way up and the terminal performance will improve drastically, and so will your point blank range.

300 mag won other than recoil.

Your. Comparison should be using the same grain to see the difference performance between the 300mag vs 7mm rem mag because of differences in coficience in bullet diameter

I like 300 Win mag

I ran into a problem with Hornady bullets item # 26331 ELDM 140gr Lot # 2212652. The diameter was .263 and .263.5 but the length was 10 to 12 thousandths difference. Ogive to base and tip to base measurements done. Compared to 2 other Lots I have on hand. I contacted Hornady and got a reply 2 days ago. Ticket I.D. 37363. Mr. Lewis, Thanks for the inquiry. There absolutely do and can see variables. With these bullets we don't have any known issues thus far and we show these to print at 1.374 +/- .007. Baring something unforeseen you can still try them. Thank you So 7 thousandths difference? I surely hope they aren't meaning what I read that as. Length and diameter?! Anyway if anyone has that lot# they should check the projectiles. I let them know in my ignorance l had 50 loaded. They are saying shoot them. No send me the box and I'll send you a box that measures right or nothing of the sort.🤷🏻‍♂️😂🤣
