I have not tried this ammo but the reviews on AR15.com and the S&W forum are not so good. As the owner of two 15-22s I have been satisfied with the Federal and Winchester bulk ammo. No hurry to try this since it's more expensive.
Edited to add - I have used CCI mini mags for years and really like the CCI brand in general. This is the first time I have ever heard bad things about the CCI brand.
ive been using the winchester m-22 ammo it has a blk/copper coating along with being round nose for reduced fouling and enhanced funtioning. i have already ran about 1500 through my sw mp 15-22 with only 3 hangups. my 15-22 also ran minimags well but they are a bit pricey and i only buy the mini mags because my sig mosquito will only run right with the cci minimags
