On a hunch I bought some of these in 5.53m head size for my P-rod. They're absolutely fantastic in it. The only other pellets this thing likes are polymags shorts and Air Arms 18gr. The H&N's put a shot dead center tonight through a 20oz soft drink bottle top at 25yds.
Sadly though they shot like buckshot in my M-rod.
