I know that many reloaders out there have used one powder for a particular caliber over the years and are perfectly satisfied, so never change. I am one of those reloaders, but did actually start experimenting with a new powder in almost all my target loads from 32 S&W to .455 and find that is especially suitable for small caliber revolvers.

Trail Boss is a high volume powder with a large min to max tolerance when loading. I stick to the manufacturers recommendations on loading, but many load this stuff like black powder and fill the case to just below the seated bullet (no compression) level and get great results. I shoot 32 Long at about 650 fps and find the standard deviation is very low from shot to shot.

Anyway, it is a tough thing to do, but I can be taught new tricks. Worst care scenario is that you wasted only $13 for a bottle of Trail Boss.
