[QUOTE="WildRose, post: 1389838, member: 30902"] Why don't you measure total bearing surface length and compare it to that of the bullets RM is shooting. Copper bullets will be 10-12% longer than traditional cup/core bullets of the same diameter and weight so I'm wondering if even with the grooves you may have more total bearing surface than he does which could affect peak pressures with otherwise identical loads.
