I need to go look at the gun and see if it is tapped, just got done going thru a lot of posts and now know to look for the plastic plugs in the receiver.
To answer your question, last year I took the gun out turkey hunting for the first time and killed two birds with it. Had the mod choke and 3" #4 Hevi shots. Never patterned it. Shame on me. Dropped both dead in their tracks at 30-35yds. Getting serious now and picked up a few different loads, thought about getting a dedicated turkey choke hence the questions. Standard sights work but are difficult for my aging eyes so thought about the red dot. Would like something easy on easy off as I use the gun almost every day during goose season.
