So what do you consider a safe velocity for this round? And what pressure (signs) do you consider safe?
I shot a HP match this last weekend, a NRA master was shooting a 6mm AR match rifle next to me out of a 26" barrel, I mentioned the velocities you are getting out of a 22" barrel with 105 and 95 class bullets, he just laughed. General conclusion among the HP guys is 2750 for 105's and 2850 for 95's max +/- depending on how you want to push it and long you want your rifle to last.
Not that I really care what you do with your rifle and how fast you can make them go, but if you are getting more velocity than others and primer pockets don't look to last for long. That is your first over pressure sing. Be careful.
Over 3000 fps plus with the 95's. Wow
I was surprised to see that much of an increase myself.
2000-mr is the slowest powder i've tried for this cal.
Whitley likes it in the turbo 40 so I gave it a try.
Others like it from the SH site also.
I don't shoot in HP matches.
I have 41 acres and my loads are for hunting when I use my AR.
I can shoot out to 450 yards at most.
I probably am too high on the powder weight with the 2000-mr since there were light swipes and small primer protrusions on some of the rounds but
I didn't blow any primers even with the shot that 3002 fps.
I tried 1 shot at 33 grains 2000-mr for that one.
I live in a cold weather environment and heat from prolonged shooting in hot weather isn't a problem.
It was however very hot for around here that day.
I should have not posted my findings because I should have known some would not believe it and what works in my barrel would be too hot in others.
It was strange that the hornady brass showed a 50 fps increase over the Lapua.
