I finally got to take them out today. I put just over 60 rounds thru them. I was checking to see how they shot, what kind of leading problems I was going to have, etc. I also shot only home rolled ammo. I shot 200 grain RNFP over 9.2 grains of Unique. They were hitting pretty good at 7 yards, shooting one handed looking down the barrel. My GF shot them using the sites at 5 yards and got pretty good groups. I had no leading problems at all. reaming those throats to .452 was a good thing I think. I still want to cut the forcing cone to 11* when I get a chance. There's something about a fixed site cowboy gun.
