I have owned a couple of rifles in 222 and I currently own a Contender barrel in it along with a semi-bull barreled Remington.
A VERY accurate round.
One of my rifles was owned by a police chief here in town many years ago. When he got a good reload for it,, a deputy & him were out shooting it. The deputy was downrange,, off to the side,, & behind a truck while he was shooting at about 300 yds. He shot one round,, the deputy checked it,, and then told him to "hold the same thing & shoot again." He did,, they met back & the deputy handed him a penny with a hole in it. I have the penny. His comments about that gun & caliber were always, "I'd bet my house on one shot with that gun."
I also made my longest shot ever on game with my Rem. 667 yds,, ranged,, on a pararie dog. It wasn't my first shot,, as I wasn't sure of the range or wind,, but the gun & I did make it after a few shots as I adjusted for the wind.
A very accurate round.
