It's an old model/3 screw Ruger Super Blackhawk. 44 mag. When I bought it last year it was stock except for the grips. I fit some current production aftermarket grips to it.
I also had the barrel shortened to 4 5/8 inches. And cerakoted the grip frame and the ejector rod housing.
The problem is that it's grouping about 12 inches high at 25 yards. My load is 7.0 grains Unique and a 240 grain plated bullet by Berrys.
From the pictures it's obvious that the rear sight has been replaced. They didn't come from the factory with white outline, did they? I don't know about the front sight. I can't tell from looking if it has been modified or not.
I shot it before I shortened the barrel and it did the same thing. The gunsmith took all the necessary measurements and said that the measurements say it should be shooting dead on at that range. Wrong.
I called another store, with a gunsmith, today. That employee insisted that if I want to lower the group, I had to raise the rear sight. I tried to explain that it's actually the exact opposite, but he insisted he was right.
Anyway, I can't lower the rear sight any more than it is because the adjusting screw starts to tap into the cylinder. It's just the way the gun is made.
One option is to replace the front sight? With a taller blade? The other option is to replace the rear sight blade with a higher sight picture?
Suggestions? Thanks.
