I heard that....
Had my last 223AI done at 22" and still get great velocity out of it. Had my first "build" a std. .223 done at 23"....Gunsmith asked me how long for the barrel, and I told him " short enough to turn around in the cab of a pickup"
It works!
On these little cartridges, Im thinking they'll burn enough powder in 22" to get the bullet out there....
