I pack my improved cylinder choke in my bag when decoying birds work in really tight. My my non ported long range PM gets to be a bit tight under 20 yards. At 40 yards I'm throwing 2's, 1's & BB's @ 95-100% on target. This is with a Beretta Urika II, 28" barrel, and Kent Faststeel 1 3/8oz. 3" mags.
I love the fact that PM offers their chokes in a non-ported version.
