Im new to this great hobby and on top of it all pistol powders are hard to find. I went to gunbot.net and was blown away at how many powders there are and the names and part numbers are mind altering. All I know about are the main ones .AA#2 AA#5 red dot win 231 unique. Everyone on earth wants these and they are difficult to find locally or even on line. Id like you guys that have tried them all to suggest some alternate pistol powders for 9mm and 45 acp. so a guy can search more effectively and buy with confidence. How about surplus powders?? thanks
