I cant get the maxi hunters to group for crap. I'd be better off throwing spears at the target. I also forgot, But my first ever .45 muzzleloader, i had issues with bullets too and i found Remington 285 grain conicals that shot great until my stock broke. I have no clue what they are called, but they are in a green box. Might just want to type in remington muzzleloader bullets and see what you can come up with. The only bullet i can get to group good are the 225 powerbelts.
