My 13yr old daughter has all the sudden decided that she wants to try hunting. (I'm estatic ) She already shoots a .243 and smaller cartridges, but until this point hasn't shown any interest in hunting. Of all the things we could hunt she is dead set on going turkey hunting. I happen to have a friend in Northern California that can facilitate getting us on birds in the spring.
What I am stuck on is that I know nothing about shotguns. I have an .870 Police Magnum 20" scattergun that I carry for bears and I could get a new barrel for it. I am afraid that the recoil of the 870 in 12ga will be too much for her. Can you use a 20 ga. ? What choke, barrel length etc should I be looking at for either guage? Better shotgun options that won't break the bank?
