If the POIs remained parallel out to infinity that would be just as acceptable as them converging at 40 yards. What is the difference in the muzzle centerlines of a 12 gauge SxS - 0.9 inches?

I used the "Shotgun Insight" program to anyalyze somewhere around 200 patterns, including POI. I shot 20 rounds out of each barrel freehand. The average POIs for each barrel were typically a minimum of 6" apart at 40 yards, both for SxSs and OUs. It is also very likely two shooters shooting the same gun would get different POIs.

There is no inherent need for convergence of the POIs at 40 yards. And divergence is probably the norm.

Best,

Mike


I am glad to be here.
