We all can kill elephants if we use 50 BMG's....you can also kill larger game with small caliber rifles/handgunsbut its what your comfortable shooting, what your shooting confidence is, which gun you feel more connected to and which will fulfill your ultimate needs. Some people prefer .243's for deer, others want .308's, there is no wrong choice (without taking into consideration of overall quality of the piece your looking at) its what you like and feel confident with. Best advice i can give is to go shoot a few different ones, different calibers etc etc....then make that decision based off what your feelings are. They will all kill...& everyone will have their own likes / dislikes..
