I have put about 1500 rounds thru mine since I got it last week. The ammo I've tried in order from best to worst: cci blazers
Federal american eagle
Aguila super extra std velocity
Cci mini mags
Winchester super X

Blazers american eagle and aguila shot perfect except for a few misfires. The mini mags have way too much wax on them. So bad I had to spend time peeling it off. I know they are coated but these were so thick with wax the tips were white and most wouldn't come out of the packaging box without force. After removing the extra wax they shot ok but did have some stovepipes and ftfeed. Super x was horrible. Constant stovepipes and some rounds didn't have any powder. I could hear a very small bang and had to check the barrel to see if the bullet made it out.
I am glad mine likes the blazers and the fed american eagle. They are the less expensive rounds and work flawlessly In my new 15-22 serial # DVP5XXX
