I ask that question due to the fact I am a new reloader and wanted to see what every one else uses as a common powder in there diffrent loadings,
I don't have one common powder. For Pistols I load for 9mm, 38/357 and 45 auto. For those calibers I use Titegroup, Bullseye and WST depending on which caliber and wheather I'm loading lead or jacketed bullets. I could get by with one powder but that's not going to give me the best performance with everything I load.
