I have one of those rifles with a clip feed The only reason I quit shooting it was cost. I could reload a 222 for less money. It was a terrific caliber. There is a conversion out there, but the sesults aren't as good as the rimfire. they were saying 2'-21/2 " @ 100yds. Mine was doing 1-1/14 @ the same range. I wasn't going to modify it with no gains. At the last show I was at in Tampa the ammo was selling for $60.00 per box, but I only have 2 boxs left and they're going to my Grandsons. performance was far superios to the mag with a tad bit noisier.
