Nope, says rifle and pistol. Straight from Hodgden web site. Possibly that "70%" info was put there for calibers where no load data is available but it still contradicts itself. Also read that you can fill the (any?) case full of trailboss (no compression) and it still won't be an overcharge. So is this saying that 5.8gr in 45 colt has 12,750 psi ( their data Max.) but going up to 8.5gr. (what I can get under my bullet w/o compressing) is still staying below max. pressure for 45 colt? Inquiring minds want to know.
