I avoid having a bunch of different powders around. I know that sounds weird but I started reloading metal about the time the last shortage hit and I just can't get that out of my head. Some powders were gone for two years along with primers. I reload for about 6 different cartridges and I find that 3 powders, 2400, American Select and AR Comp will cover the bases for what I shoot. I may try BE-86 when my supply runs low. If I like it I'll switch and buy 8 lbs of it. I buy primers in bulk also. I place an order and my dealer gives me a nice discount.
