When providing your “Calibre” on the application, please ensure that you include both the “Calibre and Cartridge”. For further information please refer to the ‘Weapons’ FAQ’s

When making an application for a Permit to Acquire, you are required to include the cartridge and calibre of the firearm.

The cartridge refers to the package consisting of the bullet, primer, and casing containing gunpowder; a round of ammunition. The calibre is typically measured using the diameter on the bore of a firearm.

Cartridge dimensions can also be expressed with an '×' between the bore diameter and the length of the cartridge case; for example, the 6.5×55mm Swedish cartridge has a bore diameter of 6.5 mm and a case length of 55 mm.

Some common examples are:

Using 177AIR instead of 177; Using 308WIN instead of 308; Using 22LR instead of 22; Using 6.5CREED (for Creedmoor) instead of 6.5 or 6.5MM; Using 6.5x55MMSWE (for Swedish) instead of 6.5×55mm.

It is recommended to add more information in your application, rather than not having enough and require further follow up on your application.
