For target .22 pistol my BIL turned me on to the cheap Walmart 550 round Federal in the red box. Money is not an issue to him yet after comparing lots of expensive match ammo, he found that the Federal red box produced just as good of results in his expensive target pistols.
My wife and I shot probably 10,000 of them through our slab sided SS Ruger Mark II and a Buckmark w/ bull barrel a couple winters ago into my bullet trap at 25'-40' practicing for a winter league. A good friend of mine thought I was full of crap until I got him to compare his favorite match CCI Select and Green tag to the Walmart stuff. He is an excellent .22 bulls-eye shooter and typically places first or second in the winter league he shoots on. At 25'-50' he could not find any difference in groupings between the two. (I am not that good at pistol bulls-eye and group quarter size at 25' while he consistently groups dime size or less at that distance with his tricked out Buckmark.) For pistols IMO, the Walmart Federal works great.
Too bad it has not been in stock for a year or so. I still probably have about 6000 rounds left, but that will not last long the next time I get on a shooting kick.
All that said, I do not doubt that results in a rifle at longer ranges are different. I will have to compare the walmart stuff with a rifle sometime against some .22 Aguila SuperExtra and some Wolf match stuff I have laying around.
