I know this goes against the basic rules of reloading, but I am thinking about trying a load that I don't have any direct data for. here's the deal: I have gotten hold of a powder that is not made anymore (Win 630), but had been used in 38 special, 357 mag, 45 auto rim, and 44 mag. Loads for those (8 to 10 grains for a 160 gr 38 special load to 20 grains for a 215 gr cast bullet 44 mag load).

Based on burn rate charts, Win 630 is between Win 571 and AA#7, and very close to both. In the .40 S&W, for a 180 grain bullet, there are loadings for both those powders between 7 and 8 grains. My thinking is that a load of 7 grains of 630 would be ok to try. Is this reasonable or a reaally bad idea?
