Brett A Wrote:123 gr. SST on top of 31 gr. of CFE
That's close to one of my go-to loads, which is 31.2gr of CFE under the 123gr SST or AMAX. Pressures are in the 46,000-47,000psi region with 31.2gr at 2.245" COL with a SAAMI chamber.
31.9gr is the max load with 123gr SST or AMAX, if you cut off at 50,000psi.
Is that an 18" barrel you have?
ETA: Corrected pressure numbers.
