Buddy of mine just bought a single shot 10 ga pardner sb2 with a scope on it and has a choke with no markings or info on it. I've never dealt with this gun or a 10 ga so I'm looking for some info on what choke he has in it, what chokes have yall had luck with and what shells? What's the choke does this gun take? Just trying to get him some info for starting places bc he doesn't know much about getting it set up. Thanks for the help.
