Walther reign. 25cal accuracy

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.
