So, my friends and I want to get into hunting wild boar. My friends grandfather has a pretty large property and a golf cart (which we could use to run from the boar if need be). The idea was to get a rifle and shoot it. The issue is, none of us know what gun to get, we all know some of the basics, but not enough. We plan on going to the shooting range to take a class type thing for begginers to learn about safety primarily.
I do not want to spend to much money and I do not need any frills, just something basic. What kind of caliper do I need? The man at the gun store recommended 270+. What do you all think? I realize hunting boar is dangerous (I have done it before, but I was not shooting, only along for the ride) and I would prefer not to get gored, that being said I am only 155lbs and I don't want something that throws me into the bushes every time I fire it. There was a 410 at the stre used for $80 but that looked like it might break my back. So basically, rifle or shotgun? Caliber? Tips? Etc. Thanks!
