This is our chuck load for a 1/10 - 24" barreled AR
.223 with the 36 gr Barnes Varmint Grenade at 4000 fps

575    -85    -14       
600    -101    -16    

Shoot me a PM if you would like to try a few of these in your 1/12 - 22" and shoot over the chronograph or get the powder and charge weight. FYI; this is a bit over max load and anyone looking for this speed with this bullet and this cartridge should use all the normal reloading caution for a max load.[attachment=1]

This is a calculator for twist rate and it shows your 1 in 12 twist just at the low side but still workable with the Barnes.
