2850 is moderate for a regular .223 with a 24" barrel. 3000 is closer to max. 3750 with a 22-250 and a 69gr is either ultra high pressure or the gun has a 30+" barrel. My 22-250 VLP does about 3500 with high pressure loads and 26" barrel. I would imagine a .223AI and a 26" barrel should do 3100-3200 with reasonable pressure. All with 69gr bullets of course. A .223AI should be much easier on barrels considering 5 to 10 grains less powder.
