This spring I'll be going on my first ever turkey hunt in South Texas. While I've done a fair amount of deer hunting and I've seen turkey on our lease, I've never actually hunted them. I have a ton of questions so please forgive my lack of knowledge. First of all, shotgun questions. I'm planning on buying a shotgun barrel for my H&R Ultra but have no idea which barrel to get. Which one- 12 gauge, 20 gauge, choke tube or not, and what length? Or should I look at buying an auto or pump? I'm assuming you only get one shot at a turkey so my H&R single should be plenty, right? Which size shot for the shells? I'll be writing in with more questions. Thanks for being patient with a rookie.
