Ok so I'm in the market for a multi purpose big bore air rifle. Me and my wife do alot of overlanding alone and have decided to buy a air rifle for several reasons. We camp alone near bears and need something that at point blank range would atleast slow one down. "we just recently had a very close encounter with one outside our tent. We camp alone on in places where phones don't work. I would also like to use it occasionally to deer and hog hunt. However it needs to be small enough to carry with us when we camp and maneuverable in close quarters. I'm debating between 45 caliber and 50. The two on the top of my list are bintac m50c with 22 inch barrel and a Texan carbine. I might consider a Benjamin bulldog if I ran up on one at tge right price. Any suggestions, advice and knowledge is welcome and appreciated. Thanks
