I sat down one day, w/ about 5-6 different boxes of various types. The distance was 30 yds (from the window of the house to the tree at the back of the yard). When it was all said and done - for my 10/22 - the CCI Mini-mags would put 3 shots into about a .30 ragged hole. That's been my squirrel getter for years.
As said many times - go buy a box of various types and try them out. If nothing else, it'll give you a chance to go shooting.
