They are extraordinarily dirty. Roll them dry in a big piece of paper towel over a colander (to catch drops) and you will be amazed at all of the stuff that come out of them. I think this works better than washing because there is no water stiction, all the stuff in the cavity falls out eventually. I did this four times and have never seen so much swarf as with these .22 Hybrids, the .30 caliber is not even close to being as bad. No other pellet or slug of any type or price has half as much crap in them as these. Just saying, hedge your bets, and do some type of cleaning, because you don't want to be trying for any kind of accuracy shooting these out of the box.
