Went to the range over the weekend with the 44 SBR, the stock 1894SS and my 1894P for a head to head comparison using some various handloads including the blue Devastator clones. It was fairly busy so I got some strange looks from the guys shooting AR15s or sighting in their deer rifles but had a couple guys come up and ask about the gun. Both seemed more interested in the Labradar chronograph though as neither had seen one before.
As expected, there was a noticeable loss in velocity across the board with the jacketed FTX loads showing the greatest difference. The subsonic loads were stable out to 50 yards but I will have to go back on another day for more testing before I risk screwing a can on the end. The hotter stuff is a real handful with a lot of muzzle blast but the little gun is a ton of fun.
