Ever body is right about cartridge selction, more info please.
My suggestion is there are plenty of good factory guns out there, but stay away from the "ECONOMY" rifles (i.e. savage edge or rem 710 or 770). Get a mid priced gun from a line with aftermarket support (rem 700, win 70, sav 10/110, sako/tikka, howa) in a cartridge that is applicable to your use, put THE BEST GLASS YOU CAN AFFORD on it, wear it out, then rebuild it with the custom touches you have learned YOU need, not the new coolest stuff on the internet.
