Anyone have a .223 load for the 55gr ZMAX using ProVarmint powder? Never used the ZMaX or this powder before.
I have had very good luck with 25.5 grains of Benchmark with most 55 grain bullets,not the fastest load but very accurate and consistent
I don't know where klmshooterk got his information but....For powder data, because this powder is relatively new, the distributor, Hudgdon, is still the only source I know of. For a Speer 55 grain soft point seated to 2.130" COL in a Winchester case with a WSR primer, they list 23.9 grains to start and 25.9 grains maximum. Use that starting load with your bullet choice and work up while watching for pressure sign.
