Anybody out there got a good load for the .204 Ruger using factory jacketed bullets like the Hornady V-Max in 40 gr. Everything I've loaded is showing pressure, even at suggested starting loads. The 1st load was Hodgdon BL-C(2) with 29.0 grs. The manual showed 28.0 grs. starting & 30 grs. max. I even have primer cratering @ 28.0 grs. but no noticeable flattening of the primers. At 29.0 grs, the primers are flattened & cratered. I also tried IMR 4064 & IMR 4895 at mid way between starting & maximum and the cratering continues but doesn't seem to flatten too bad. I just shot the last factory cartridge I have & it is cratered but not flattened.
Anybody got any ideas what's going on? Brass is once fired, full lengthed resized and trimmed and primed with Winchester small rifle primers. Bullets are seated to 2.250" cartridge OAL as per manual & factories and some were seated out to 2.360" to allow for freebore, which I measured and backed off .030" as I do in everything I reload.
I appreciate any advice or experienced.
