Jack,
If my rounds fired off hand are not going where the gun shoots them from a steady rest, then the problem is me, not the gun sights. It will be carried in a belt and shot off hand once it is shooting to POA. I don't and have no intention to shoot this revolver at 25 and 50 yards. Don't know why your 452423 is casting such heavy bullets. The mold is designed to cast 238 - 240 grain bullets. I also cast this bullet as hollowpoints, and they weigh about 225 grains.
