I murder a lot of schit with rimfires every year. I'm talking thousands, not hundreds and the Mini Mag is ALWAYS accurate enough for squirrel sized game out to 75yds. And I've yet to see it not feed or cause problems in any 22LR. Bolts, autos, you name it.
It's the gold standard as far as I'm concerned. It may not group best in every firearm but it groups well enough to get things done.
If I had a rimfire that had issues with MM's, I'd tear that rimfire apart and find the problem.
