My shotgun patterns best with full choke. (steel)
I used factory full a whole season. This year a club member generously gave me a Briley's Extended Range Full choke.
I LOVE that thing. I either hit or miss and if I hit a duck...it's D. E. A. D.
Been "poofing" teal from 30-40 yards easy.
I tend to let other people get off a shot before I shoot. At close ranges my pattern is too tight.
