How much do you use behind a 55gr bullet? I've been using 27gr's for years, but now everyone shows that is too hot. Hornady list's 23.2grs as max! | ||

SPR SP, 2.200", 24" barrel, 3203 fps, 49,300 CUP Test: Ruger #1, CCI 400 small rifle primers, LC brass once fired processed from Scharch and prepped by me, 55 gr Vmax moly, H335 pic left to right: unfired, 28, 29, 30, and 31 gr. unfired, extractor groove .329" 28 gr, extractor groove .329", 11% overload 29 gr, extractor groove .329", 15% overload 30 gr, extractor groove .3295", 19% overload 31 gr, extractor groove .3320", 23% overload picture of brass and primers I like to run 6% below the slightest growth so that would make my personal max somewhere between 27.25 and 28.25 gr. I would need to expeiment more to resolve that. | |||
