I'm thinking of sending my Savage 12BR bolt to Gretan to get it bushed. This rifle shoots good for the money but I get badly cratered and pierced primers quite low on charge weight. With 105 VLD hunters I got pierced primers as low as 29.7 and nearly pierced as low as 29.3, the brass shows no signs of pressure from the ejector. I see guys on here running similar loads up to 31-32 grains, I'm sure a lot of these guys are running custom actions that have much tighter firing pin channels. Just curious how much it will help.
