Ok I have a stock standard Winchester mod 70 XTR in 264 win mag. It has a 24inch barrel. Its bedded and floated, it has a Tasco 3*9-40 scope(its crap) I want to make this into a tack driver at 500 yards. Since my nearest gun shop is 100k away and the 264 mag is not popular over here. Any help would be great. I am not worring about loads, just the rifle. new barrell etc......
