I take it "unplated" means the ones that look brass-colored rather than the silver?
I've got some of both colors actually.
So, should I save the silver WSR for semi-auto use?
Guess you did not read my first post (btw color does not matter)
Most dont like WSR's for semi-auto use because they are thinner and softer,
WSR's cup thickness .021" Rem7 1/2 .025" CCI 450 and BR4 .025" better for semi-auto
