[QUOTE="Wallie, post: 2975648, member: 107256"] I use CFE223 for all of my 223AI loads now, but I’ve had good success with 8208XBR, AR Comp, shooters world Tactical, and Ramshot Tac. It’s nothing special really, 223 AI 26” 8 twist 6 groove barrel with .060” freebore ran in AICS magazines so the bullets don’t take up much room in the case. My 53gr vmax and 80g ELD-M loads both like about .015” off the lands, the vmax will crank all the way up to about 3650-3700 when the bullets start turning into grey puffs 50 yards out. I run them at about 3500fps just because it seems like a good compromise between performance and efficiency. The 80g can go up to about 3200fps before I run out of case capacity (or rather compressing the powder that hard starts deforming the ojive) but they seem to like 3100 much better accuracy wise. Probably the “secret sauce” is the HbN powder coating on all my projectiles. My family calls it my pixie dust. It’s pretty easy to do, and seems to help. I get 4k rounds on a 223 barrel now with pixie dust where I only got about 3k before. If you headspace an AI chamber to properly headspace regular 223 rounds the accuracy is superb while shooting vanilla brass (I don’t call it fire forming, I just call it shooting!) [/QUOTE]
