Yes...and it's not a fluke barrel...I have multiple.45s in1:48" twist,both caplocks& flintlocks...and they all shoot the .45cal/255grn Maxi-Hunter like a heat seeker missle.....I use 100grns Goex 2F, an Oxyoke wonderwad, and the 255grn maxi-hunter.

I'veoften thoughtif I could only keep one rifle, it would be a.45cal x 1:48" barrel...they're extremely accuratewith both the 128grn/.440 Round Ball and the 255grn Maxi-Hunter...throttle back the .440 with 30grns Goex for a small game and target load...up to the good size maxi-hunter for big game...that's a lot of versatility
