I have been shooting CCI Blazers in My Ruger Marks for several years. They've been utterly reliable, accurate, inexpensive and easy to find. However, the last few 525 round bulk boxes I've purchased seem to be extremely waxy and dirty; so much so that during a 500 round fun-shoot last Sunday, my magazines fouled up so bad they needed to be "de-waxed" twice. There were about 18 shooters, and 2 others experienced the same thing with Blazers. Any comments and/or similar experiences ??
