I have had them in a 221 Fireball, 222, and 223 are were great. The Fireball is the only gun I can say that I truly shot the barrel completely out on. I had another one in 222 and I bought it used (as I did the 221) and it was ok but not great. I found out why when cleaning it after the first trip to the range, the barrel had a very small bulge in it (no wonder I got it for the price I did) Once you felt the patch get loose, and knew where to feel, you could feel it on the outside (once again very slight) Anyway I sent it and had a new barrel put on and chambered it in 223.
The only trouble I ever had (other than the barrel issue) was with an extractor. I broke one on the Fireball. I found out that they made a long extractor and a short one. My fireball had a long extractor and I like to have never found a replacement for it, but I did and all was well.
If I could find another Vixen 461L action at a good price, I would love to replace the ones I sold.
