Welcome form Oklahoma via NY, PA, KY, OH and TEXAS. I also had a 357 BH bought in 68. My first Ruger. Had it drilled and tapped for for scope mounts. I loaded 95 gr 9mm bullets over 2400 and chronographed them at 1900 to 2000 fps. I think the pressures upset the bullets enough to fill the bore. The gun was great to about 150 yards. Now I have a new model 357 BH (also scoped) among many others.
