Rattles, the CCI value packs are identical to the boxes of 50. I shoot them almost excusively in my 15-22 and 22A without problems. If you've shot the boxes of 50 without issue, don't hesitate to get the 5K from gunbroker if your planning on buying that much.
Thanks for the info. I wil order some after I get the $$ together from some Ebay wheelin' n' dealin'.
CCI makes the best rimfire ammo; Blazers are good, pretty clean ammo. Locally I get them at Dunhams sporting goods for $1.99 per 50
Thats what I used for my "test" ammo.
