RE: new hunter here
Walmart has any gun you want. They have a book that you can look at if you don' t find what you want in the store, anyway just ask for that book and if you find a rifle that you want they' ll order it for you. I would suggest a .243 it is a pretty awesome rifle. It has less kick than a .308 and it' s not very heavy. Remington 7mm .243 is what I use.
