Gidday - I'm shooting the ballistic twin of 6.5 PRC - a 6.5-284, the case capacity of the Norma brass I have is exactly the same spec as that of 6.5 PRC. Rifle is a Savage with a 24" barrel. Obviously COAL , chamber and throat design isn't going to be the same but it's still going to be very close.
So I read all the "internet " claims for both these 6.5s and thought I might get close to 2900 or even 3000 fps - I thought wrong! I got to 2850 with pressure signs at 56.5gns 2217. I am going to try some Lapua brass as GRT says my pressure at that should be 61,000 psi.
But the take home story is that many of the loads you see on the internet are likely to be pushing 70,000 psi and that's asking for trouble!
