Tinkering with getting a 30-30 lever action as a tracking rifle but struggling with the 1700ftlb minimum.
Looking at GRT the PMax for the cartridge is 46,412psi. I can get to 1700 ftlb and 2350 fps and stay within pressure. Yet Hornady LeverEvolution ammunition manages 1950 ftlbs and 2500 fps with 140gr bullets. Everything I play with says they are at about 55 kpsi which is way over SAAMI.
What am I missing??? Help.
