I've been shooting .22 rimfires for about 35+ years.....I started out shooting CCI mini mags (both solid & HP versions) because they were usually on sale at the local Kmart; if not, then I was shooting Federals (Lightnings? Power flites? Cant remember for sure). Since that time, I've tried a lot of different rounds...but the CCI's have not only been accurate, but consistant from lot to lot (I usually try and buy .22 ammo in bulk).
Federal American Eagle ammo runs a close second....accurate in all my rimfire firearms.
My Uncle used to swear by Winchesters, but I swear
at Winchesters! Of all the ammo I've tried, these were the ones that had the most failures to fire.....good ammo, if you shoot it from a slingshot!
I've had good luck with the Remington "golden bullet' rimfires, but the plain lead bullet (Peters as well) had too much 'gunk' (lube?) on the bullet, and the powder leaves a lot of residue, gumming up my semiautos.
I've also tried a lot of foreign makes, but the problem with them is that they are there one day and not the next.......had some good stuff from Czechleslovakia, but couldn't find it again.
I'm sure we've all had issues with one of the many 'promo' (i.e. bulk loads) from the various manufacturers....stands to reason, as the stuff is made to be cheap, so quality control isn't as good as it could be. Not a big deal if you are popping cans or paper, but when I'm hunting with my .22, I want it to go "BANG" all the time.
BTW: the same follows for all my .22 magnum as well.
