RE: New rifle buyer.
I don't know of anyone making a rifle on the market that won't shoot .So who made it is up to your pocket book . From what you mentioned I would recommend a 30-06 first and a 300 win mag second . I own both of them and it just depends where and what I'm hunting which one I use . Get a good scope and you should do fine . The only scope I wouldn't recommend is BSA ,We have one of those to .Good Luck
