Wow! Good info for me to file away in my mind about ASM Schofields Jim. Sounds like they had a bad production run on the barrels and by what happened to 44 AMP, the barrel latch and internals as well. I've owned several other ASM black powder revolvers in the past that I shot and had no problems with them. So maybe it was just the ASM cartridge using Schofields that had negative issues.
Oh, to answer your question about how my ASM .36 sheriff model is doing after five years, she's still an unfired (by me) safe queen. After the gold plating started flaking off the fluted cylinder of one of my 1860 nickeled Pietta .44's, I was afraid to shoot the ASM and am still waiting to find a stainless fluted cylinder for it like I bought for both my nickel Pietta .44's. Last time I checked, Cabela's where I bought my fluted stainless cylinders for my Pietta's, doesn't even have those anymore. So it was good that I got them when I did and they have worked great in shooting them. So far, I've been unsuccessful at finding fluted stainless cylinders for an open top colt clone .36 caliber. Might just have to settle for a fluted or solid blued one. But maybe not, I have my two white grips nickel .44 caliber 1860 Pietta's, my Uberti .44 caliber 1858 Remington, a long barrel Uberti carbine .44 caliber 1858 Remington and my CVA mountain rifle in .50 caliber. So I've got plenty of other black powder guns to shoot, so no hurry in finding a stainless cylinder for my .36 caliber ASM. Sometimes I take it out of the safe just to admire its engraved nickeled beauty. Like a piece of art. Know what I mean?
