I also went back to the " Ecotungsten " site, through the link show on this site, and NOW, the day after Christmas, they are showing they have #2 and BB shot available, but not #4 shot. I think it would be worth while calling them to see when #4 will be available. Two days ago, #2 and BB were not available, but they listed #4 as being so. If this is a daily thing, they may just take your order for a " KILO " of the stuff, and fill it by the time your order is ready to be processed.
I have an old, cold roll steel DB 12 Breechloader, that I would love to use on Geese and ducks again. However, until this Ecotungsten comes on the market so I can reload shells for it( I am using Brass casings to give the old gun a bit more protection from pressures) I can't do it. So, thank you for finding this, and bringing it to our attention. Maybe things are going to look better. I am concerned because tungsten is a much more expensive metal, and I don't know how most people are going to be able to afford to practice to learn to shoot a shotgun well if lead is banned. Tungsten is also not as commonly found in the USA as lead is, which leaves us dependent on foreign trade, and subject to executive orders controlling imports that could shut down the source of ammunition for the guns we shoot.
