H&N 21 gr.

The wind died for a couple of hours today and I finally had a chance to test a sampler pack. Here are the results at 30 yards. If you will click on the image you will notice most of the fliers are actually an ink aim point. I may have finally found a slug this Wildcat compact likes. One question though, the one hole group is the .217 21 grain H&N HPII slug. I can't find this slug for sale anywhere. I assume it is actually the H&N .217 21 grain slug and they do not make an HP II in 21 grains. Is this correct?
