That is a shame to hear of the decline of Super-X. I still have most of a case of it bought around the turn of the century and it is as accurate as anything else short of dedicated match ammo, and still close on the heels of that.
Same thing happened with cheapo Wildcat ammo. A friend and I bought a few 5,000 round cases at K-Mart for $90/case (1.8 cents/round, the good old days
) back in the mid-80's and I used that up through the late 90's to win several smallbore silhouette matches. When it ran out I bought some recent production stuff and it was crap.
CCI AR-Tactical seems to be pretty decent, I stocked up on that before Obama II and it shoots great in all my .22's. I see they've raised the price and lowered the round count - used to be 375 rounds in a bulk box and now it's 300 - but Cabela's and on-line dealers seem to have a good supply so I should probably get a box to evaluate.
Before Obama II decent ammo was around 6 cents/rd with the cheapest bulk around 4 cts/rd, now it looks like 9 to 12 cents/rd for good ammo is the new standard. I think you can get bulk stuff for a bit cheaper but for the past few years the bulk .22 ammo I've bought shot so badly it seemed to be false economy to buy it unless I just wanted to make noise and roll tin cans at close range. Geez, just gonna have to not think about it costing a buck every time I load up the 10/22 magazine...
