Blue 67mm

BLUE 67mm

Especially designed cartridges to replace those with lead and steel shot.

Ideal for game shooting as the special alloy shot has similar softness to lead and deforms slightly on impact, thereby dispatching quarry more effectively.

They can also be used with any nitro-proofed barrel (that is in-proof) and of the correct chamber length, as well as with any choke.

This is particularly good news for the owners of older guns who no longer use lead and cannot use steel cartridges.

There are no ricochets too.

All BLUE cartridges are SP (Standard Performance) except #3 which are HP (High Performance).
