I met a guy selling a Howa heavy barrel .223, pretty sure it is a 1/12 twist. I would a bought it but for the twist, but the price is right at $550. It has had maybe 3 rounds through the bore and there are a couple scratches, but iti is otherwise new. I don't know much about Howa. What say ye? Can I shoot 68 grn out of it? reason I am asking is I have about 400 match of the Hornady 68 grn heads laying around. Looks like a decent gun.
