I recently purchased a used contender frame, several barrels, scopes, dies and bullets in a package deal. One of the barrels was a 7X30 Waters in 12" ported. I personally don't care for ported barrels because of the noise, but the guy said he had gotten outstanding groups with this barrel and I hate to sell something that shoots well. The only problem is the guy had lost all of his load information and only had the targets he had shot as proof of the barrels accuracy. Anybody out there shooting a 7X30 Waters in a 12"? If so, what types of loads are you using?
