I had one in 20-222AI Kevin Weaver calls it a 20Bobcat. Insanely accurate with N133 and anything you put on top of it. Don't have any data anymore because it went down the road with the rifle. Sold it because I had custom action 20 tactical. Fed great no mods in a 700BDL. 11 twist Pac-Nor spun everything including 55s. 35gr Berger knocked some coyotes in the dirt out to around 200yards.
