I have a Ballistics Specialties 20 gauge Remington choke I bought from Rob Roberts a ways back. It's stamped "turkey" or "tky" or similar...I cannot remember. It measures .555 at the muzzle with calipers.
Ive only used 3" #7s and #6 Hevi 13's. The patterns with these are fantastic for hunting.
Anybody have one of these and tried it with TSS?
Thanks!
