I use a gold in a 3".Use a truglo strut stopper choke with winchester HV#5's. Not sure of the choke restriction though.Taken lots of birds with this combination over the last 6 years out to 45 yards.Haven't crippled any yet,knock on wood,but I'm very careful about shot selection. If I'm not sure I can make a clean shot,I'll let them pass and try to get a better set-up.
