Thread: A400 choke changing poi

What is the pattern master constrictm ent.. Is it the same choking as the original.. How did you confirm the split pattern etc.. Obviously same load and did multiple shot pattern boards.. Although it maybe 50/50 on the other choke remember pattern board patterning is 2d..meaning if it was going to hit the board no matter how far the shot string is it will hit it.. Actual shooting the same chokes on live birds etc. You may find that the aftermarket choke may have a shorter shot string.. Meaning more of the pattern gets to the target together.
