Gary Wain’s pel­let test­ing in the Au­gust is­sue high­lighted an of­ten over­looked con­sid­er­a­tion. The skirt de­for­ma­tion of the Nor­ica Killer pel­let is, I be­lieve, caused by the pel­let ‘wob­bling’ in flight due to lack of gy­ro­scopic sta­bil­ity. Much like a child’s spin­ning top wob­bling as it slows down. This is also high­lighted by the pel­let’s poor ac­cu­racy.

I think this is what causes dif­fer­ent head sizes of the same pel­let to ex­hibit differing de­grees of ac­cu­racy. Too tight or too loose a pel­let will af­fect its speed and thus gy­ro­scopic spin rate. I don’t think enough con­sid­er­a­tion is given to pel­let head size when test­ing for ac­cu­racy. al­though Jamie Chan­dler talks about it in the Septem­ber is­sue of Air Gun­ner, and the only man­u­fac­turer to ad­dress this is­sue is FX with dif­fer­ent spin rates of their bar­rels.
