Best powder for AR15 w/16 inch barrel?

I, too, use 8208XBR.

i use H335, IMR 8208XBR, and WC844 pulldown powder from GIbrass.com that uses the same data as H335. i know a bunch of guys that use varget and CFE223 and love it. i just use the first three because thats what i have data for and i can readily find or already have.

H322 brings it in the 16" DD chrome lined barrel. SD of 10, boys.

(that's 77 gr smk.. not 75)

I've really been enjoying the H322. Worked up a very consistent M193 clone to match all the factory ammo I have stocked up. I wish I would have tried it with the 69 SMKs and 70 TSXs before I loaded them all on top of Varget.
