David Sinko Posted November 10, 2007 Share Posted November 10, 2007 A few years ago I bought 100 new unfired nickel plated R-P .45 Colt cases which I had intended to use for serious field use. After the first firing the nickel plating was literally blown off around the mouth and back about 1/8" to even 1/4". I could then grab the plating and start peeling it off in large flakes. I have never experienced this before and in my experience very heavily utilized .38 Special and .45 ACP cases will simply fade to brass color but never peel. I just bought 100 new nickel plated Starline cases and I hope it does not happen again. This stuff is getting very expensive. Was this just a bad batch of R-P brass?

Kingman Posted November 10, 2007 Share Posted November 10, 2007 I have lots of nickel .45 and .38 special brass and the only thing I have seen is fading over time and use. I have never seen it flake off, except some from my major 9 open gun. Link to comment Share on other sites More sharing options...
Scout454 Posted November 10, 2007 Share Posted November 10, 2007 I've seen nickel flaking a few times on RP .38 Super brass. Don't know how new it was though. It could have been loaded many times. Link to comment Share on other sites More sharing options...
al503 Posted November 10, 2007 Share Posted November 10, 2007 With nickel, you have to be careful of how much you bell the brass. If you're using jacketed bullets, reduce the bell to a minimum (just enough to accept the bullet without crushing the case when seated.) Link to comment Share on other sites More sharing options...
kevin c Posted November 14, 2007 Share Posted November 14, 2007 I've rarely had some flaking of nickel plating on the mouths of R-P .40 cases, but that was with multifired brass and a fairly aggressive bell. Mostly it's a gradual wearing off of the plating from overly enthusiastic polishing. The cases weren't trimmed to length, by any chance? That might expose the boundry layer between the base metal and the plating right at the case mouth. Just speculating here, but I suppose that could cause hot high pressure gas to work its way under the plating. Link to comment Share on other sites More sharing options...
