About 18 years ago at a small gun show in Texas, I saw an example target from a guy that was selling a "custom" 700 .222: 50 grain Nosler BT over 25 grains of AA-2520 with a Winchester small rifle primer. Not the usual powder recommendation for a .222, but I had lots of 2520 for use in .308 match ammo, so I gave it a try in my SAKO AI Mannlicher carbine. I've never messed around with any other handloads in that rifle since that time, because I don't know how it could get any better.
