300 Weatherby top velocity! 

Quite spicy! Thanks for showing the results.

Happy birthday. That's probably one of the best ways to spend a person's birthday. Spending a day at the range shooting rifles with friends and family.

You did fine job of shooting that .300 Weatherby! A .750 inch group would be fine with me for a hunting load. And Happy Birthday.

Happy Birthday Austin. 🎈

Happy Birthday Austin! It turned out to be a great birthday celebration at the range! Nice groups, crazy velocities with your 300 Wby. You were into 300 RUM territory and just about nipping on the heels of factory 30-378 velocities. And you found your pressure limits. A productive birthday at the range!

Woot woot! 🎉 Happy Birthday man, wishing you many more 🤙

Happy Birthday Austin. 🎉🎉🎉🎉

Happy Birthday! ❤❤❤

Happy birthday man! That 300 is a shooter. I would be confident with that fine rifle. You can easily tone down the charge and still enjoy mega velocity and 4k ft/lbs. Those lead free bullets will open up no problem. Hammer down man!

Happy Birthday!

Another good video good shooting boys and happy birthday

My 26" Sako 75 .300 Wby loves maximum loads with the bullets just touching the lands and grooves. I use only RE 22/25 for my 300wby loads. Up to 200 grain partitions.

Happy birthday Austin 🎉🍻🍺

Didn't know it was your birthday R. Dub; shoudda said sumpthin. Wouldda gave you one of my Weatherbys! Happy Birthday! 🤣

Great shooting

Nice shooting! That scope looks like it has really good eye relief

Happy birthday!

Hope this is the best birthday of them all. Happy Birthday, and many happy returns of the day! You are slinging a 170gr 30cal bullet 3400fps. That is hauling the freight! How far are you jumping and what is the barrel length? I couldn't see any ejector swipes but definite craters. I had a Savage Axis 1 in 6.5CM. I got a deal that I could not refuse. After I trimmed and polished the seer, it was a very enjoyable gun to shoot. A really accurate factory rifle that was extremely easy to work on. I love Savage rifles. Thanks for another great video!

Sorry I'm late, happy birthday dude

Happy birthday 🎉🎉🎉🎉

Would have stopped after the 2nd shot on that ladder test, maybe even the first. Over pressure is not simply a well that's not quite enough overpressure yet. Looks like that last one was extremely close to being a complete primer blowout. On the positive side it certainly appears that your dedication and efforts are leading to some pretty strong load work-ups. Nice work.

Hey happy birthday!! Mine was March 10th.

Glad I got to celebrate at the range with you and you didn't blow me up!

Happy Birthday and Thanks for the Great Videos. I see you are using R-P brass which I have found to have less volume capacity than Weatherby or Nosler brass. I would try loading the same charges again in Weatherby or Nosler brass and redo the test.

I love to see the same test with a 30-378 then some with say 130gr TTSX. I sold my TRR back in 2010-2011 and it was a lazer w factory ammo. She's not efficient with the light stuff but I bet we can kiss 4000fps with a 130TTSX and a 28" barrel. Who's got a 30-378 in the comments to lend Reloading Weatherby for a test ??? Love the content my man!

The 30-378 Weatherby achieved over 6,000 FPS from a custom made test rifle for the US Army, to test its performance against armor.

Happy Birthday

Dang that weatherby had quite a bit more velocity than I expected

Happy b day man

I have owned a Weatherby Mark 5 with a custom 30inch barrel for 40 years. I bought it to shoot at a 1000 yard range plus take elk hunting. I have used RL 22 for many years . I have hunted coyotes with 100 fmj and taken coyotes at 600 yards with little adjustment. With those bullets i could shoot direct on target at 250 yards. I don't buy high end bullets like barnes or any solids but a good standard bullet that opens to a size of a nickel,up to 600yards. I have taken elk or deer at 600 to 800 yards and each time .the animal dropped.

everytime i watch these videos i want a 300wby even more. Mind says 30-06 but heart says go big and go 300wby

Oddly when I hear a discussion of cartridge "efficiency" I start to shut down. Usually, not this time, the term is used to describe a new cartridge that is NOT as fast as what it is designed to surpass. Personally I don't concern myself with those things. If it delivers a bullet at a higher velocity and more punch, I like it. Do I need that higher velocity? How can I tell, the buck/bull didn't complain. My Ram 2500 is probably not as "efficient" as a Prius , but I don't care. Good video RW. Cheers, Jeff.

Anything about 3000 I’m fine with. I have learned the Nos 180 gr BT pretty much blows up on WT deer. I use those in my 30-06 now.

I'd like to see more hunting videos of yours I just saw a short with you shooting a doe with the 300wby on bullets4bucks video. How far was she?

😢 the Fourth edition HORNADY book has gotten a Max load for a 180 GR bullet using 85 GR of RL 22.

Happy birthday. Did you get a 340wby for your birthday?

H1000 my friend

3400 with a 175… pretty crazy. I‘ll put that into GRT to see what pressure you are running there 😂 What kind of an impact shift do you get with and without the MagnetoSpeed hanging off the barrel?

If you’re not blowing primer’s once in a while, are you even alive? Those light rifles look like they kick like a mule. 😂 good times. Looks like you guys had a good time. Hoping I can get the the range later. My daughter starts her 22 rifle competition this month. Just got her a new Christensen Arms Ranger. Shoots pretty good. Didn’t see much difference between the expensive Lapua rounds and the CCI Standard Velocity target rounds. Win for my wallet there. Carry on.

You've really seemed to struggle to get the .270 to shoot well. Have you tried bedding the stock and check the clearance between the barrel and stock? That can make all the difference sometimes. I was chasing different bullets and powders in one of my dad's rifles trying to get it to shoot for him and when I started getting frustrated I took the time to get the stock bedded and the barrel properly free floated and everything came together after that

I have always sat my Barnes so the first ring is showing in every cartridge have you tried seating out a bit more should have lots of free bore to play with

Happy birthday! Have you ever checked watercapacity diffence between wby and rem brass? I bet that there is the answear why you get higher velocity than barnes load data is showing...

Do you think i could do 150grain bullets with BLC-2 powder maybe starting around 60grains? I have data showing 150grain bullets starting 61grains of IMR4895

Okay about 30,,,35 or so years ago I bought my dad a box 110 grain 300 Weatherby ammo,,,,now nobody around had a chrono but everybody was curious about the velocity, ,,do you or anybody anybody have a idea???!!!! Oh yeah it's a Mark V i think a 27 in barrel????

3320

7828 is the powder for that weight bullet !

RE 22 and RE 25 are my favorite powders for my .300 Wby!

Need faster? 30-378

I imagine you are careful with bullet selection you could push a .300 WBY "accelerator" load north of 4500fps, really it would be a question of if it would stabilize and if the sabot could hold up to the speed.

Do you think it's worth getting a 30 inch barrel in a 300 wby and a 300 rum.

Spicy girl. I wonder why your gun shoots so hot?

Try reloader 26 should be better.

Your gun doesn't shoot "Fast" your just overloading it, almost every fired cartridge you show has signs of over pressure....what blows my mind is you know it because you comment on it, keep that crap up and you are asking for trouble and a ruined gun.

Happy Birthday!
