Used the ".44 Boys" at a match in Ione, CA. I did 60s rounds of pure pleasure and "hit where you point." I have to say that the 1860 based revolvers are the "pointing-est" ones around. Very sweet shooting. I used some Black Hills .44 Russian factory ammo at the match. Hit basically close to POI/POA at 7-10 yards.
Saturday I am doing the local match, and think I will use some of my .44 Colt reloads: 205 grains .428" over 5.7 grains Trail Boss in a Black Hills .44 Colt case. I think my next bullets I buy will be 225 grain .430s. Closer to the original loading and Black Hills 230 grain .44 Colt.
