Ruger Old Army shooting low?

I second all that's been said before. Find your ideal load first.
One of the bizarre things about BP revolvers is that they need a certain amount of power to acheive accuracy. Too little is as bad as too much. This was proved to me when I started shooting my Roger OA at 50 metres. My normal load was 23 grains of black powder and I thought I would up it to 30 to cope with the extra range. Absolutely hopeless. Of course what I should have done is to stay with the normal load and wind up the sights 3 clicks which is what I did do eventually. Obvious when you think about it. My friend had a Pietta revolver that just wouldn't group. I found he was only using 15 grains. When he upped it to 20 things started to improve dramatically. This seems different from the old Police Pistol days when we used to use 3.5 grains of Bullseye at 25 metres and 1.9 at 10. (In a .38 special of course)

Think it was a JOKE

Think it was a JOKE

It might not be!! I was just looking through the GUN DIGEST for 2000 and there was an author who suggested bending the barrel of a Colt SAA to correct the aim. Until then I'd never heard of this procedure. Very hit and miss I should have thought unless it was bent to start with.
