Ok, I figure it can't hurt to try them. Honestly whether they work or not I'm going with Barnes once they are used up. Actually if they don't work, I'll go with Barnes sooner. Do you like the new barnes muzzleloading sabots with the new point? I haven't tried them as they don't come in .54 cal but I might try them with the new .50. Barnes makes the best muzzleloading bullet I have ever tried. Sure they are a little hard to push down the barrel. Who cares? I load my gun standing up with the scope facing away and the gun held between my knees. That way, I can use both hands. I shot a deer season before last in the neck, big doe. The bullet went all the way through the deer lengthwise and exited on the top of the rear leg. It didn't even tear the meat up too much. A bullet that expands then offers full lengthwise deer penetration on a big deer. They are excellent. And very accurate in my TC thunderhawk even with 1:38 twist.
