Owning a 223 is like having a bunger
I have 2 Sako L461's in my safe and one Remington in 222. I won't make claims to any accuracy, one or the other, but most 222's I've seen will put 5 in a 1/2, sometimes regularly with any old bullet.
If pressure of the load is same/same your looking at 150 fps., MAX. Factory ammo, is of course lower pressure for the Deuce.
If looking at a 222 Mag or 224 Ruger, they'd do same/same too, maybe more as 223 AI.
I wish there was still room for all of them; its ironic the 221 was such a smash, when it doesn't do what a 222 does. A nice M7 varmint sure sounds good.
Rem. still makes the 798 in 222; I got the last of the 700 BDL's in Feb. 08. By March they were no more
