I have a Nova 12 ga., which I use for a variety of game. What would be the best choke tube to acheive the tightest pattern from 00 buck. I have shot at Deer and missed at 30-45 yds because the patterns is to broad, using the full choke tube. Should I be using the imp. cyl. ? If not what tube is available for purchase which would tighten the pattern? Your assistance addressing this issue is greatly appreciated. I also use the Nova to hunt small game using no. 4 & 6 shot. With these loads the patterns are consistently tight and deadly.
