Anyway, Eley are adamant that they are truly biodegradable, as opposed to merely breaking down. Could be the future. I have some now (took a month to get them, mind), suitable for ordinary game/rough shooting in an ordinary game gun (or so I am told; not super steel) and so far so good- cannot tell the difference from lead. But it is early days, admittedly. I once purchased some carts that had plastic "photodegradable" wads. Those are the worst of all - sure, they break down, but only into tiny pieces of plastic which cause even worse pollution etc than larger pieces. I just saw the "degradable" bit on the packaging - didn't read it properly. So similar to the packaging material made from corn starch that dissolves?

The Poly Lactic Acid plastics (corn starch derived) such as the Photo Degradable wads were overhyped as whilst they are recyclable and do degrade (dissolve into smaller pieces over timescale of up to 10 years, causing micro plastics , which eventually subsequently degrade over 10's of years) due to UK ambient temperatures and conditions they still hang around for a long time and are still plastics (just derived from a recent bio source rather than an ancient one). The new wads are supposed to be much better, dissolving in hours and degrading in weeks as the starch is not polymerised to the same extent. However due to this rapid breakdown in presence of moisture, i believe all cartridges containing them need plastic cases to be heat sealed as any dampness would start the breakdown.

figgy Posted October 29, 2019 Author Report Share Posted October 29, 2019 Watching what mudpatten said and showed even being heat sealed some that had three outings on foreshore the wad had softened. So air was getting in somewhere. I think I would wood some petroleum jelly over the primer to seal it and wipe off any excess. Could even dip the crimp in varnish to make sure.

Careful, that might dramatically increase the pressure! Quote Link to comment Share on other sites More sharing options...
