excellent to hear. I am betting the 400gr limit again was orininally due to the older models. UC reported that CVA did testing on the accura and it took 600grs Triple 7 3f and Three 444gr bullets to make it go kaboom. With a 150gr loose powder load, bullet weight should no longer be a worry. I dont know anyone crazy enough to use a 150gr load for hunting with a 400+ grain bullet. That mental picture alone makes my head hurt. Shooting a ramrod gives more than enough kick
