Picked up my midge on Friday shot it yesterday. Ive had a hard time getting any real db info on this can so it was a bit of a gamble but Im very pleased after shooting it. Performance on my .22 was about the same as other .22 cans nothing amazing, but my primary use for this is as a up .223 can. I dont have a reliable db meter but to my ear it was def hearing safe on my 20” tikka .223 and psa 5.7. Fully reliable on the 5.7 no booster too. It is borderline hearing safe on my 16” ulul .223 (no gas system) but just fine for a few shots hunting most likely. Very happy w the can for the size and weight. I see no reason to use a heavier can on a bolt 223 in a low fire volume hunting situation.
