Bought 2 8lb kegs of Alliant Herco 1 keg of Alliant Unique and 2 kegs of IMR 700X. Paid 65 bucks a keg so I know the price was right...It has been years since I have used 700X(shotgun only) and even though I know it is a good 12 ga powder I don't really load 12 ga..And I can find plenty of data for 700X. But never used it in handguns. What do y'all think are the better handgun calibers to use 700X in? Target and midrange loads The Unique and Herco will be used in 20 and 28 ga. One keg of the 700X and one Herco are going to a shotgun shooter. I have been told that 700X is comparable to Bullseye...never really used it either. As far as handgun calibers I load....most are the usual suspects. Oh how does 700X go through Dillon powder measures?
