I certainly agree on the TC Maxi-Ball being hard to beat. In the quest to turn muzzleloaders into flat shooting long range deer killers, we've lost sight of just how effective pure lead heavy conical bullets are on heavy game. I am fortunate to get to hunt elk every year, and have taken many bulls with the muzzleloader. Same goes for my friends, my adult son and his friends. I settled on the .54 caliber 430 grain maxi-ball many years ago, and it hasn't failed me yet. I've killed bulls from 15 to 100 yards and the bullet is usually recovered just under the hide on the far side. Sometimes there is complete penetration and they will break both shoulders! They are accurate in my guns. I shoot older Thompson Center guns, a System 1 inline with a 1:38 twist. I also have a Black Mountain Magnum in .54, with a 1:38 twist. TC introduced this side-lock when Colorado temporarily banned inline guns. It looks similar to a New Englander (round barrel), but has the faster twist. My son and his friends have all bought used Fire Hawks in .54 and they are great guns. Maxi-Balls also shoot well in the TC Hawkins and Renegade with their 1:48 twist. I shoot peep sights, can't use a scope here. They shoot as accurately as anything I've tried with the iron sights, and I wouldn't consider shooting over 100 yards at an elk with a muzzleloader. Unfortunately TC doesn't sell the .54 caliber Maxi-Ball anymore. I have a TC mold, and there are still folks casting and selling them.
