Hey is there anyone out there that owns or owned a beartooth magnum .50 cal. muzzleloader from B.P.I.? I'd like to know what would be the ideal bullet and type of powder works best in this gun. I bought a replacement barrel from b.p.i. and it's a 1:28 twist. I've had about 20 rounds fired through it and cleans really easy. I'm a rookie at this and any wisdom would be greatly appreciated.
