I just picked up the basis for my next project gun. A Savage 110E from the pawn shop for $250. Its currently chambered for 270 Win. I'm looking to change the caliber by way or a barrel swap (an E.R. Shaw fluted heavy barrel most likely) and possibly swapping out the bolt face as well if necessary. I have a Choate Ultimate Varmint stock that I took of another rifle that I plan to put this in. I'm looking for something to shoot targets at 500yds plus with reasonable groups (2-4 inches, for fun not competition). I already have rifles in 30-06, 25-06, and 308, and I would like to try something different, maybe a magnum cartridge. I reload so ammo cost isn't a major factor. A couple I was thinking of were 338-06, 7mm-08 Rem Mag, 300 Win Mag but at this point I'm wide open to suggestions.
