That is true of some powders, Gil. Particularly IMR 7625, as I recall. I have loaded it for years with no problems, but Miller (and others) has said that he has had bloopers with it. Probably the difference in the temps between here and VA during the hunting seasons. I"ll bet'cha I am on the "edge" of having pressures low enough to cause problems in lower temps, at 5800 psi.
