O can run 180 Bergers at 3100+ With N570 but its pretty compressed

I concur, you can't out physics physics!! If you want more velocity, shoot a 6.5 300.

I couldn't agree more. And along with that, just because a round is smokin hot does NOT mean that it's going to shoot well!

There's a guy on fb long range forum in Australia, that posted one of his 1000 yd F class matches shooting the 300 WSM at 1000 yards. The video was taking from behind him so you could watch the bullet trace all the way to the target. It impressed me to the point, I've bought a barrel and ready to have it machined. though I'm going with the 300 SAUM, only because I have the brass and dies and it's scary accurate in every barrel I've shot.
Good luck with your projec!

300WM performance in a mid length action. Sounds interesting. I like the sound of that 7mm pushing a 195 @3050-3100 in a 3.3 length cartridge.
Good luck with that!

210vlds going 2850fps from a wsm still winning at Williamsport. I shoot one also but I'm switching to a 7 for the bc advantage. I also run a 6.5creed in my 17 pounder and it shoots 147eldms at 2975fps all day long with great brass life. Long barrels and rl26 the speed is there. My wsm has a 34 inch 1.450 barrel and I still shoot it in the 2850 range. It will go 3000 but they shoot unbelievable at the slower speed. At 100 yards mine shoots as good as any 6ppc I have ever owned.

A 83 grain H20 case is NOT going to push 195s 3050 at a safe pressure in a 26" barrel period. It amazes me how many of you are so close to loosing fingers, eyes, or your life and you have NO CLUE!
Some of these pressures are insane. It the field one extra screw up, dirt, etc and BOOM!

This is a whole other topic. Most bullets are more accurate at 2850-2950. Case capacity and efficiencies have a huge effect on this.

Pretty sure he stated 86 not 83. Someone else stated 83 grains. Either way, time will tell. Nobody is going to blow up. Good thing YOU have a clue, cause I'm not sure we'd survive without your concern. There's a few hot rod loaders in every group. Don't make it sound like everyone here on this thread are extreme speed demons only looking for maximum speed and disregarding safety. We all want best performance and safety combined. When some one states 3100, I'm pretty sure 3000 will be the reality and more than likely better accuracy velocity will be lower and up too 3000. It's definitely an interesting cartridge and one to look forward to seeing develop. Safety is always first in this game.
