[QUOTE="6.5x300, post: 1169034, member: 10713"] Shilen 26" 12 twist barrel 32 grain V-max bullets Viht N-133 powder CCI 450 Primer LC brass I consider 26 grains of N-133 to be about max for our rifles. I have tested up to 26.5 but you got to use a drop tube and it is certainly over max psi. We have also found that the Shilen "Select Match" barrel develops pressure sooner then their standard "Match" barrels, I suspect the "Select" has a tighter bore. The only numbers I found in my books for the moment concerning loads with the N-133 and the 32 grain V-max is as follows. These where shot from the 26" Shilen Select Match 12 twist barrel. [B]I don't recommend anything over 26 grains of N-133 when using mil brass and the 32 grain pills![/B] Anything over 26 grains would flatten primers with an occasional popped primmer. We settled on the 25.9 grain load that we run in both our guns. We have found Winchester commercial brass to operated at a lower pressure as it doesn't have any problems in the "Select" barrel. Grains FPS 25.7 = 4140 25.9 = 4185 26.1 = 4230 26.3 = 4265 Hot! 26.5 = 4290 Too Hot! Be safe!
