Regarding my article on sorting rimfire ammunition in the "How To" section of this website, rather than re-writing that article to include some actual figures, I will publish them here, and will add to them as time goes on. This blog is the closest we have to include rimfire.

Groups shot at St Marys indoor range at 50m using an Anchutz 64 GPR rifle and 24 X BR scope. These figures are averages of several 5 shot groups in each case.

These are from my early days of sorting, with ammunition which may no longer be current. However they illustrate the point that significant reductions in group sizes can be obtained just by sorting. In group or score BR events, sorting can easily make the difference between running first or last.

Eley Subsonic HP; sorted rounds by weight and rim thickness 0.560" +/- 0.157" (variation between smallest and largest groups).

Eley Subsonic HP; unsorted rounds 0.798" =/- 0.433".

Difference between sorted & unsorted groups is 0.238" or almost 30%

Eley Club (standard velocity); sorted round groups averaged 0.354" +/- 0.057"

Eley Club (standard velocity); unsorted round groups averaged 0.67" +/- 0.216"

Difference between sorted & unsorted groups is 0.263" or almost 43%

Wolf Match Gold (Lapua) sorted round groups averaged 0.420" +/- 0.110"

Wolf Match Gold (Lapua) unsorted round groups averaged 0.599" +/- 0.045"

Difference between sorted & unsorted groups is 0.179" or almost 30%
