[QUOTE="boomtube, post: 842415, member: 9215"] "Can powders of similar burn rates be substituted?" Sure. Who knows, you might even get lucky. But, how are you going to know if any adjacent two powders in the charts are similar burn rates? The book lists are simply given in order of burn at a specific pressure and there is no calibration or predictibality between chart steps. Two adjacent powders may over lap so much as to be nearly identical but the ones either side of them may have a wide difference. And, chart burn rates are NOT the same throughout all usable loading intensities, Jam any powder into a totally closed space - a stalled bullet momentarily jammed into the rifling for instance - and the rate of pressue increase skyrockets; that's what drives SEE problems. But, other than all of that, powder swapping is a simple thing to do. [/QUOTE]
