Denser patterns

[wayne goerres]

I use a over powder card in the bottom of the shot cup to bring the shot level even with the top of the shot cup and then a over shot card and roll crimp. I have also tryed a 6 point crimp.

[10 bore]

try a shot at 40 yds at a 30 circle. count the hits and divide that by the number of pellets in the load. my be you have a gun shooting cylinder choke (45 %). if so that would tell you why you have holes in your pattern. at forty yds you should get 70 % to 90 % on a .030 to .040 of choke out of the short 10 ga.
