NOW . . . ya'll got me thinking.
I have an "extra" NEF Handi Rifle chambered in 223Rem. This gun would be super easy to ream to AI. Will check on renting reamers.
Might be an interesting,after deer season,project. Load it up 'til the primers blow then back off .00001gr. Got plenty of brass and several hundred of them old NosBalTip's.
Whatdaya think . . . 4000 with a 40 ??? YEOWZA !! --- SAWMAN
