ok guys, i asked yesterday about indian creek chokes, and i'm convinced. i'll be ordering one pretty soon. this is my question now. i normally shoot #5Federal Premium flight controls, but i read that the indian creek black diamond strike set the world record shooting 3" #6 hevi 13. the only thing i worry about is that the constriction for my benelli with indian creek is going to be .665, and i've heard hevi shot performs better with more open chokes such as a .670. i know that going too tight can blow your pattern, throwing huge gaps and holes in the pattern. so will i be safe with the hevi shot even with the tighter constriction, or are there any other loads that perform well with indian creek that you suggest?
