You can do it with bismuth/tin alloy but not with Ecotungsten/NiceShot. That is a suspension of tungsten powder in tin matrix, with a tin coating on the pellets, and separates if you melt it. The inventor said on his blog that he was considering making round balls, but I haven't heard anything further. For casting round balls, it is probably cheaper to get bulk bismuth/tin alloy from suppliers like Rotometals. I believe Rotometals is now offering a 7% tin alloy specifically for that. Bird shot is normally made with 3% tin, although some individuals use a 5% alloy, and larger balls, especially for rifles apparently need higher alloying for toughness.Turkhunter said:Wonder what the melting point is on that stuff and can it be cast into round balls?
Woosdeguy, NiceShot is just spherical shot - no belts, rounded cubes, or anything else odd.
