Congratulations on that Fox

I believe that I took my first with a WMR. I used that .22 mag exclusively until the Coyotes started showing up and I jumped up to a centerfire.
Your 1.5" five shot groups are great for hunting situations, especially since you are shooting from sitting or prone positions. I am thinking that if you (Benched) that .22-250 out you would cut that group size in half or better.
