A great little cartridge, I have a very early Sako L46 .222, I purchased with a shot out barrel. Wanted to rebarrel in a .20 cal. My gunsmith friend talked me into a .20 VarTarg. Which is a .221 Fireball necked down to .20cal. I'm sure glad I took his advise, while fire forming cases I put 27 of thirty shots into .507" Wish I could post pictures I would post the target.
