In reference to .45 Colt loads, I have read that a 270ish grain cast boolit on top of 12.5 grains of Blue Dot is considered a standard pressure load. One article in particular was written by Brian Pearce. Are there any factor information sources that support this data?
Alliant only shows this:
.45 Colt, 250 gr Speer LSWC, Brass-Winchester, OAL 1.6, Barrel 5.5", CCI 300, Blue Dot 12.9, 1,028 FPS
QUESTION: Does anyone dispute that this load is a standard pressure load for the .45 Colt (14,000 psi or less)?
Thank you
