Ballistics Specialties 20 gauge Remington "Turkey" Choke with TSS

[Scott Hunt]

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!
