Not sure about the higher end guns, but my crossman wasn't rilfed, but it can in a way be compared in someway to a old muzzleloader shooting round balls to that of one that shoots mini balls, both out of the smooth bore. I shoot coperheads, but mainly shot regular zinc coated bbs, I also shot pellets. Usually I just shot the bb's becuase it had the 15 round magazine on top of the reciever, and another 200 in it, pellets where one at a time, killing power seemed to be the same, same with accuracy.
