First, don't buy ANY of that crap, light, Box-Mart bulk milk-carton "333", 550 round, "555" type stuff. the buyer dictates the price and then the manufacturer cuts corners. It is junk. Cheap. Popular. Junk. Now if you use it please don't start swearing by it -- there is no point and you are only embarassing yourself.
Aquila used to make a hi-speed, low pressure, Eley-primed .22 Target ammo that sold through the DCM (CMP now -- I'm getting old). See if you can find this (Centurion/Aquila Golden Eagle Target, 40 Gr., 1,200 fps). Was $250 a case of 5,000 more than two years ago, delivered. Quite nice ammo for the price but not sure it is made anymore per se.
Federal AutoMatch. $159/3,250. Above those cheap milk-box average accuracies and 1,200 fps too. Federal's lower-end target ammo's are ALL worth testing a box of to see what you might want quantity of.
Armscor Precision Target .22. $200/5,000? Above those cheap milk-box average accuracies too.
Again, if you avoid those cheap milk-box ammos, and anything Winchester (AWFUL bullets) as a rule of thumb, you'll be better off. Actually, CCI Blazer, which can be had for well less than $200/5,000 is above milk-box average accuracy though I think they package some that way too.
