It works great in my Omega and outperforms 777 by about 15% with less felt recoil and that is data over the chronograph. I think the barrel length may be the deciding factor as most other positive reports have been from longer barrels than the 22 inch one. I will have some discussion with Magkor reps to see what they can add to this data. Thanks for the information and the other people I suggest you do not make a decision based on either Mark or my data but if you have a longer barrel rifle I strongly suggest you give it a try as it is the cleanest thing out there and will perform in some rifles.
