Welcome aboard. Warning .22 rf shooting is addicting, one rifle will lead to another. I go to a well stocked sporting goods store and I buy single boxes of .22rf shells of as many brands as I can. Now I have my testing stock, each .22rf is a different animal in the same make or model. People ask for the most accurate 22 rf shell, I have no idea what it is, like I said each rifle is different animal. That being said, take the advice already given, try the promotional rounds first, if they prove accurate great. My problem is always trying to find the most accurate in that particular rifle, that's my addiction. But the most fun is plinking and squirrel hunting. Hope you enjoys .22rfs as much as I do.
