Eley have brought out a steel game cartridge suitable for 2 1/2" chambers but still caution against using in choke tighter than half and not in the softer Damascus type barrels. The wads used are bio-degradable. They look and act like plastic but are made of plant starch. They go to a snotty mush in water and safely disappear into the ground. Bio-Ammo is another maker of degradable steel cartridges as is Jocker. The move is not just away from lead but also from plastic waste in the environment. Most game shooting here is done with felt wads and some clay shoots don't allow plastic wads either. One clay ground I have been going to since the 1970's have never allowed plastic wads in all that time. It seems that quite a lot of research is underway here by the ammunition manufacturers to find an inexpensive round that can be safely used in older English guns. Lagopus…..
