if yer really into all manner of trad bp guns, bulk mail order is the way to go. order out 25# and be done with it. that lasts me a year as i use a LOT for bpcr so i'll order 25# of swiss, with a mix of 1-1/2f and 3f. if you only use 10# or less per year, seek out locals (friends, clubs, ads in local town papers, etc) that will mail order with ya. start doing the seeking well before ya run out of powder.
