Re: ideal velocity for 155s
Out of AI AW 2950 fps 24" barrel, out of 22" Kreiger 2920 no pressure sighs or enlarged primer pockets. Due to recent advances in powders easy to reach with out being hard on cases. Before primer pockets might start getting loose after 4-5 firing and would have to reform with a Hart primer reform tool, doing that and annealing those cases have 20+ firings.
The advances in powders has changed what is safley possible such as the velocities RL-17 has given the heavy .308 bullets ( 190, 210 208 gr) the ,243 shooters as well as the 6.5 x 47 are rewriting what is possible.
