Tim,

Have cast Postell in the past but now use a standard grooved Money bullet, for my 45-70, it drops from the BACo mold at 510g in 20:1 lead time (by weight). My 40-65 uses a 390g Money, again 20:1 lead tin and BACo mold

Both bullets work well with BP using SPG lube and a blow tube - don’t hold with wiping personally

For ref. paper patched I use prolate bullets but cast a bit harder at 16:1, have to wipe for these though.

Brgds
