I have a used Marlin 880 SQ .22 that looks like it had a bad recrown done on it.
Can anyone recommend a good gunsmith in SE Mich. that can recrown this?
Thanks

You can clean that up yourself if you are handy. Take a brass, round head machine screw that will fit the end of the bore. I would start with a #10 or #12 screw. Chuck it up in a drill motor and use valve lapping compound from your friendly local auto parts store to lap the edges of the bore. Rotate the drill motor as you run the motor and work slow as you go.
Have you shot it? The crown below was found after removing a muzzle protector from a 10-22, thousands of rounds as a loaner LTR. It still shot 2 MOA groups.

Thanks all,
After about 300 rounds by me it shoots OK but not where it should, inconsistent.

I agree, that looks like it could be cleaned up not to hard. Go easy and work slow. Worst case you have to take it to a 'smith and have it crowned. (But you were thinking about doing that anyway) Best case you learn a new skill, make your rifle shoot better and you save a C-note.
