Re: Cutting Edge 375 Bullets
I have been using 50 BMG and US 869 with the 375 and 400 gr . The 375 gr with 142 gr. of BMG yeilded 2960 and 148 gr of US 869 yielded 3080. The 400 gr was pushed with 140 gr of BMG for 2850 and 146 gr of US 869 yielded 3010 fps.
They dont seem to be fussy about seating depth, start with a case trimmed to standard length and kiss the case mouth with the seal tite band for a starting point. I suggest that you refrain from seating the seal tite band into the case mouth because it seems to cause run-out problems.
