I am a R-P and Winchester guy.  For no particular reason beyond that is the ammo I bought over the years and retained the brass.  I only shoot the Win stuff in my M1895 Musket and the R-P in the Krags.  Simple logistics because I have three or four boxes of Win brass and the rest is Remington.

I can't speak to the number of reloadings since my case are only on their third rotation.  PSteinmayer and Butlersrangers can address the brass quality issue.  I do believe there was a post in the last month or so about that.

The bottom line is I have never had any brass issues.  They are both good stuff.  Well.  One issue.  I don't have enough to sustain a .30-40 Gatling gun for fifteen minutes of constant firing. :o
