My job was slightly different as it was a Colerain turkey choke when I sent it to him. He had to ream out the taper choke before jugging it. Its a 20ga
I'm very confident it'll take a turkey at 30 yards. Probably further. Guys have claimed GREAT patterns to 40+yds with a jugged gun but I've never seen jugged patterns better than mine posted...I count holes and want a certain density before I call it a turkey gun...I'm not happy with a couple hits on a turkey target...
Also have taken 3 deer with it with roundballs. Very versatile gun.
