Fowling was not a problem, and there was uniform pressure seating each bullet. Calculation shows that getting 1400 fps would raise recoil from 58 lbs to over 130 lbs. I'm not sure if I would be better off just raising the front sight so impact would be 4" lower at 25 yards. If sighted 3" high at 25 yards, it would be dead-on at 100 yards.
