• SK v Eley with Feinwerkbau Rifle

What does the group size mean?

Use the chart below to work out how a group size determines the performance of a .22lr barrel for ISSF shooting.

An X indicates a “perfect 10” at 50 metres.

For Example

A 21.24mm group centred on the bull should score a 10 at 50 metres. A 60 shot group within 21.24mm, scores 600.

Bring on a gold medal !!!

If you are shooting all your bullets into the “perfect 10” the group would be 12.24mm or less, scoring 654.

A World Record and Olympic gold medal !!!
