Honestly, I havent bought much rifle powder the past 4 years from American except for some of their black friday discounted sales when you buy 16lb or 32lb.. And even then its been things like MW H335, AA2230 or 2250 to run large qtys of 5.56 on my automated 1050 for AR plinking rounds.... Prices just arent the huge crazy deal they used to be... Hopefully they come back down.
The other powders are great like MW IMR4451, MW AR Comp, MW 8208, MW VVN550, MW VVN133 but the price the MW powders have risen to, I just buy the real thing for a few more dollars.....
I have been buying their 8lb pistol powders for my 9mm, 45acp and 10mm which can still be had for a good deal in the $125-$145 per jug range.
