I had one built on a Savage 110 back in the 90's. It was my first experience with a wildcat.

I'd have to look for my data on it but, but I seem to recall 3050 FPS with a 165 grain NBT and RL22 gave me good case life, this was out of a 22 inch barrel. I finally figured out it was easier to just get a 300 Win Mag.
