I'm looking to trade my Primos jelly Head choke in .660 constriction that fits the crio choke system( Benelli SBE II, M2, etc.). I'd like to trade it for another choke that fits the SBE II. The choke I have is about 3 years old, and has had 30+ shots through it. Here's a pic of the choke, and of a pattern I shot with it shooting the hevi 13 2.25oz 7's from lot number 300326.
