My scope is almost twice as wide as the rifle. Scope rings won’t fit around the slots running along the top. Should I file it down on the top?
The dovetail grooves on a .22 are smaller than the Weaver style rails on center fire rifles.
You need different scope rings.
Before you file anything down, you could get a dovetail to weaver adapter.
Here’s an example from Brownnells- https://www.brownells.com/optics-mounting/rings-mounts-bases/rifle-bases/3-8-dovetail-to-weaver-adapter-prod18690.aspx
