CCI Standard Velocity is a great "tweener" load - generally provides very good accuracy in a broad range of rifles and is less expensive (especially by the brick or case) than any real "match" 22LR ammunition.
I've had really good luck with Federal Auto-Match. It's more accurate and reliable than other bulk pack stuff, and you have to be a good shooter and have good equipment to tell the difference in accuracy between it and "the good stuff." My 10/22 loves it, and everything else I have does good with it too. I haven't found any .22 rifle or handgun that doesn't like it.
Palmetto State has it in stock (and has had for a while now) for $26/325 before shipping. Limit 3 boxes.
Agree on both of the above, CCI standard and Federal Auto-Match. There are probably others. When Midway has Federal in stock, it's $17 for 325 pack, limit 1.
I have a number of different makes/models of rimfire. Of course CCI Mini-Mags are the standard of reliability and accuracy IMO. However, my Tactical Solutions AR-22 like Lapua Master-L for a 1/2" group at 50 yds on a calm day; but it won't cycle the bolt if the temp is below 65*. All my rifles like Federal Auto-Match & shoot well with it.
