After some more testing, I'm still not sold on the reign. Shot it across the chrony and came up with 650 to 780 fps in 21 shots. That is a change of 120 fps. I tried different fill pressures and the same thing. It would be close for about four shots then jump by 10 to 15 fps. I can not get one 9 shot mag in any kind of sweet spot. It will be a good group for about four shots then jump out to close to 2" group for few shots and stay there. I could understand a flier opening up a group by 1/4 to 1/2 of an inch. It may settle in after I break it in. May go back for a refund. The gun shoulders good and balances good. It is right at my budget but not sure if I want to fool with it.
