My local Tactical rimfire club has quite a few CZs. I have a standard MTR barrel, there are a few more MTRs, a few Proof SS, a few Lothar, and there was a guy with a Lilja but he just sold it and bought a Vudoo.
At least for the NRL22/PRS22 side of things I see a benefit with a larger / heavier profile for rifle balance on barricades. I don’t however see much accuracy benefit inside 200yds. My MTR at the last match took 5rds to zero: 3 under 1/2” at 50yds, 1 @ POA at 100yds, and 1@ POA at 197yds. The 197yd shot was at a rock about the size of a tennis ball and the impact was near center. This is very typical of my barrel, provided I clean the snot out of it after every match. It does not like to shoot dirty, at all.
I don’t think the high end barrels shoot any worse, and may even agg better, but I don’t see enough difference over the MTR barrels’ accuracy to justify the $$$ for myself.
