The 10/22 still throws the occasional flier but the rifle typically shoots around 1/2-5/8 MOA at 50Y and 0.75-1 MOA at 100Y for 10 shot groups with Wolf Match Target on calm mornings. It is more difficult to shoot consistently accurately than my Sako Quad but I'm quite happy with the rifle. I don't shoot it as much as the Quad nowadays for paper, I use the Quad for prone paper punching and the long range stuff while the 10/22 gets used primarily at the 50Y silhouette range for practicing position & offhand stuff. It's way more accurate than needed for the silhouette range and keeping the 10/22 off of paper keeps me from scheming and spending more money and time on it trying to eek out a little more accuracy & consistency.
Before barrel threading it was more like 1.0-1.75 MOA at 100Y and far less consistent, I could never seem to get it to group with any consistency.
A couple years back a few weeks after having the barrel and receiver threaded the stars aligned and I shot a 10 shot group at 200Y that had 9 shots that were within about 1.5" and one flier that made the group about 2.35". I have the picture still somewhere. I was dumbfounded when I went down and looked at the target, couldn't believe it. I've never been able to come close to a similar 200Y group since.
Regarding Wolf Match Target, after chronographing several hundred rounds of Wolf MT in one day I found there are usually 2-5 rounds per 50 round box that shoot about 25 fps above or below the average velocity of the rest of the box. Those rounds with the well above average velocity deviation may only slightly open up a 50Y group but they make a big difference on the 100+ Y groups.
Accurizing a 10/22 is a money and time black hole, that's for sure. Having built a couple now it's cheaper to do it once than do it multiple times so I'd do "best practice" up front-- good receiver (Kidd), good barrel (for >50Y I've had good results with KIDD and Volquartsen but there is no guarantee you'll get a good one), thread the barrel to the receiver, use a good bolt (aftermarket or trued factory), a good trigger, and pick a stable stock with a good bedding job. It's no guarantee you'll have an extremely accurate rifle at 100Y+ but you should still have very good results.
