I recently purchased an MK3 Wildcat .22 compact (tube) version. As of today, I have run just under 500 pellets down range. The only thing I have done to my new gun was 1st day I removed the barrel and cleaned it. I did turn the barrel, so the transfer port was on the slug port. I ran it over the chronograph then and today. I am very pleased with its performance and consistency. I'm pretty much getting factory specs on shot count (60) @886fps average with a SDV of 1.6 Today I also reversed the transfer port to pellets. It dropped 20 fps from the slug port on the thimble, so I returned it to the slug port. I usually let a gun break in before I try adjusting/tuning it as I believe that's the number 1 cause of problems/issues with new guns.
