20G Bismuth

New Premium Non Toxic

Gamebore have always been at the forefront of cartridge development and innovation and our New Bismuth cartridges continue that tradition. 

As the UK's only shot manufacturer, we have turned our expertise to Bismuth and using a revolutionary production technique here at our factory, we can now produce Bismuth shot using a unique process that results in superb, uniform, malleable shot which performs like lead and eliminates the issue of shot shattering as seen with Bismuth produced using the more traditional method.

Bismuth is the closest material in terms of density and softness to lead and so has no restrictions on choke and can be loaded in cartridges with a standard fibre wad.

Totally safe for the environment and for use in traditional game guns, these cartridges deliver everything you expect from a Gamebore product, namely the highest quality and outstanding performance. 

Loaded in 65mm case length in 12 gauge suitable for most guns including traditional English game and a 70mm 20 gauge load, these will suit the most discerning of game shots where a lead alternative is needed. 

All cartridges should be stored at room temperature in a dry location. Adverse temperatures may affect performance. Do not expose to extreme temperatures.
