I was loading up some 55gr fmj ammo I just got from Everglades ammo, Win 748 powder. My mind wandered, (not a great thing to do whilst reloading, but..), I had been loading to 2.200", the thought struck me to load longer. I've been working loads up with different powders, amounts, etc., haven't really played with length. Decided to load some at 2.215", didn't want to go much longer, there is a cannelure, didn't want to go out of it. Is there that much a difference in OAL as far as accuracy? The gun is an AR, 16" barrel, 1:9 twist.
