I don't use any of these fancy muzzloader bullets.

ShockWaves may shoot well, but are too expensive.

Powerbelts are crap. Occasionally the plastic skirt seperates from the bullet in the barrel. The result is the bullet tumbles instead of spinniing missing the target. I have been told this doesn't happen if you use loose powder, but I use 777 pellets.

I buy Hornady 240 grain .44 cal hollowpoints that would normally be used for pistol cartrage reloading. I box of 100 cost about $20. Then I buy a bag of 50 of the green Hornady sabots. With this combination I get cloverleafs at 100 yds. Every deer I shot with this dropped in his tracks.The only problem is the sabots dry out after a long time making them hard and difficult to get down the barrell. I am going to try boiling some of them to see if that softens them up.
