I found CCI Stingers!
Heres a number to a pawn shop in South Carolina that has Stingers for $10.00 per 50. Im new here and just wanted to help, I ordered 500 rnds, they shipped the next day. 1-803-536-1711 Give them a call, hope it helps. Ohhh, its Hyper velocity ammo, not for use in match barrels. My new 15-22 loves them! Finnally a 22lr rifle that states in the owners manuel CCI Stingers ok, as long as it doesnt have Performance Center markings!! I went threw 3 Umarex H&K MP5SD's before a friend turned me on to S&W 15-22, great gun S&W!!
