6.5x300 WBY
Well-Known Member
Ok this topic is right up my alley here.
6.5x300 Wby has a better barrel life than what most would expect. If treated properly for a big overbore cartridge you will be easily get 1000 out of her. No Prarie dog shoots or rapid fire at the bench. Give it 3 to 4 minutes between shoots and your golden.
Powders I have settled on US869 Period. N570 and velocities suk. Atleast in MHO. 153.5 Bergers with N570 maxed out around 3150. Awful. US869 I am at 3250 with absolutely ZERO pressure. Soon as it cools to 50° and below I have more loads to see what I can get before I hit pressure.
Now, yes I hear all the comments about US869. Yes it's temp unstable I agree. Totally indisputable. But if you love your 6.5x300 use it for it's strengths not it's weaknesses. ITS A GAME KILLING EXTRAORDINAIRE. KILLING MACHINE. Why in the world would anyone bring this out during the summer for fun shooting. Correct answer is NO ONE.
Work your load up during hunting season or after it before spring and summer gets there. Clean her up and light coat of oil and put her away till next season. I am sure most have other rifles to fill in for fun shooting. If you use your 6.5x300 like this it will last and US869 works amazingly well. Oh I LOVE US869. LOVE IT. 16 LBS ON MY BENCH READY FOR COOLER TIMES.
BRASS. Weatherby factory ammo uses multiple manufacturers of their brass not just norma. Found that out from the source. But I can confirm absolutely that Peterson is having a run coming up in this 4th quarter just a month or so away. Buy early as I'm BUYING BIG TIME. I HAVE about 150 cases or so between factory ammo and factory new Cases. At the time I didn't know that they use 3 different manufacturers of their brass. So I was told that I can call them and they can tell me what manufacturers it's from from The headstamp. So I have that to do. But I am pretty much going to buy a good amount of Peterson brass and go with that. But will see what brass I have from weatherby. If it's all the same I'll continue to use it till it's dead brass. But from my early reports it's pretty dang good so far.
Conclusion.
Use this cartridge for it's strengths and heed it's weaknesses and you will be blessed with a Killing machine that for factory ammo is the flattest shooting cartridge in the world. ( yes I hear you wildcatters. Factory cartridges even if it's proprietary in nature).
Trust me you will love it.
Best of luck
