I saw an ad in a hunting magazine for a muzzle loader that claimed 2900fps with a 350gr bullet. I was astounded by this number and looked through my reloading manuals to see which cartridge this was the closest to matching. You'd have to go up to the 460 Weatherby Mag to get that kind of performance out of a center fire rifle. The 378 Wby Mag only shoots 300 grain slugs and 2900 would be around it's hottest load with the bullet thats 50 grains lighter than this muzzle loader shoots. Does anyone know anything about this gun. It's got to be pretty painful to shoot, as well.
