Underhammer maiden voyage

[harleysboss]

I finished up my Underhammer the other day so I packed my shooting box and hit the range for a test fire.
The barrel is a GM LRH 50 cal 1-28 twist. I used home cast 420 grn conical and 75 grn of Swiss ffg, 1 54 cal wool wad over powder. Just 50 yards for the first trial run. Shows promise I’d say.

Yes, absolutely shows promising results. Beautiful work, also..
