Interested in what shooters are using for bullet ( brand and weight ) and powder in 300WSM. Bought a Encore barrel from Bullberry and having a problem with the tight neck and short chamber he is using. loads 2 grs under max are leaving black around primmer. I have a good friend that is a bench rest shooter that is willing to throat the barrel out to any loaded ammo I decide on so looking for good load. Will be used on Mulies and Elk. I plan on 150 to 180 gr bullet.
