Just joined the site- purchased a new Prohunter Synthetic Stainless in 7mm Rem Mag. Need advice on barrel break-in procedure, and where to get a bore guide to fit this model. The net is full of often-conflicting advice on this, so I would appreciate hearing about methods that work on Steyr barrels. I want to get this rifle humming before next deer season. We get to shoot a lot in Alabama, and I like to make every shot count.
