Any of you guys using (or used) RWS brand primers in place of Fed215's in magnum casings? 300win mag, 264 etc etc There's very limited information on them out there. As far as I can tell they're more of a European primer than N.American... seen a few comments relating to 50bmg & RWS primers, but really nothing anyplace tying to smaller cartridges. I'm curious whether there's any significant difference in Ignition (with RWS) vs. a fed215 ?? I have 100 new primed brass that came with RWS primers, haven't loaded any so far, thought I'd do a little reasearch first to see what a guy can expect (or not expect) out of them for ignition on H1000 or Retumbo type slow powders. Any feedback be appreciated. I don't personally know anyone shooting these primers.
