I don't have that barrel but.... I made one from a barrel blank for a 45-70, for more info on smi barrels go to "doug's muzzleloading message board" there you will see a forum called "savage smokeless muzzleloaders" once there do a search for smi or just look around in the forum and you will see some of the guys praising their smi barrels. They say they are real shooters.
