That thing shouldn't be picky at all. The vast majority will take anything 22 lr. Even mix em up. But the answer you're probably looking for is CCI mini mag. This is a good plinking round. Others might do better, and everyone has a favorite. But mini mag is a good place to start. But don't let the lack of a certain ammo stop you from shooting. Just buy the cheapest you find, and you'll be fine. If there's any real recommendation it would be to get the McFadden speed loader. Money well spent.
