Hi, just joined in and I have a question. I recently took a stainless steel 1851 Navy Colt (made in Italy stamped on barrel, no maker) that I haven't fired in around 25 years out to the range...don't remember what loads I used to use, but I was a lousy shot then. I'm really good now with modern handguns.
Anyway, using 20 grains (smallest measure I have), I clustered all six together at 10 yards, but 5 inches high.
I backed off to 15 yards and got the same group 10 inches high!
At 20 yards, I was over the top of the target frame even aiming at the bottom, at least 15 inches.
I read that Colts shoot high to print dead on at 75 yards, but that's insane trajectory that no sight change is gonna fix. I can't get more than 30 yards from the target in my back yard.
Would reducing the charge flatten trajectory, or would it be the same, but slower?
