This will be my first season turkey hunting and I'm very excited about it but I'm not sure what I'm getting into or what to expect. I have 2 shotguns (both winchester pumps a 20 ga. and a 12ga.) that I have had since childhood for deer hunting with slugs. I asked my friend if they would do and he said yes. Neither has a choke on it and I'm not even sure if you can put a choke on them. Here is the confusing part. He said I should get some turkey shot 3 1/4" for the 12 ga. but I can't find 3 1/4" shot am I missing something here or is he wrong?
