Yep 220 swift! Typo! I am shooting factory ammo today and tomorrow just to work on sighting my scope in. I will reload this ammo with nosler varmageddon 55 grains. That will probably be the max bullet size since the twist is 1/14. Once I bench rest it I could shoot it 1/2 inch for sure. Glad to be part of the forum. New to reloading but an old pro at handgun and rifle target shooting. I read a story about some pro just filling up 220 cases to top and seating bullets??? Crazy. I will stick to my manuals!
