45/70 bullet casting

[enfield2band]

Using wheel weights and always overfill each chamber. May try a pure lead/tin mix and see what difference I get. Iv been casting for 45/70 for many
years but have only noticed the size difference recently. When I sold my Ruger number 1 I let the mold go with it. Wish id kept it now.

Check your wheel weights are lead. The new ones are made of zinc and zinc shrinks unevenly when it cools.

You might check the weight of your cast bullets. A wheelweight bullet weighs in at around 80% of a pure lead bullet.......don't ask how I know.
