This mold was terribly undersized and slightly oval, it was casting at .221"/.222". The drive bands were recut using a special cutter and a Bridgeport EZ Trac CNC milling machine to drop WW bullets at a perfectly round .2253". We are able to accurately measure the existing drive band diameter with a toolmakers microscope and recut it larger based on your as cast size with extreme accuracy on the CNC mill to drop the proper size casting to fit your needs.
RCBS 44-300-SWC with one cavity altered to remove the gas check and enlarge the drive band.

Bands in this unknown maker mold were recut to cast at .458 for high powered air rifle hunting use.
Milling on sprue side performed on these molds to shorten the base band creating equal drive band lengths to customers specifications. .065" and .090" removed from the molds.
Nice little bullet with a Cramer-style HP conversion for the 32-20. Drive bands opened up to cast WW at about .313".
Mold altered to customers specifications with a matching diameter .090" wide drive band added near the nose. Small 3/32" diameter HP conversion with matching top punch is primarily for improved alignment during sizing and seating etc. not for expansion purposes. Note enlarged meplat diameter of altered cavity which improves energy transfer upon impact.
