I'm still not clear on the purpose of the research. Surely, no hunter or top classed competition shooter is interested in one pellet hits. Don does bring up an interesting point, though, if I read him correctly. Does a competition shooter on a long run of hundreds of targets have to worry about factors other than not being "on the target"? I think that may be exactly the case. A skeet shooter who has broken 1242 straight is just as likely to have that run broken by a slightly defective load than by "missing the bird". At least that is my opinion.
