For my time, casting HP's in lead is mostly pointless. Plus 230 grainers use up too much lead over the 200 grainers. Unless you really like the extra work and have tons of lead. [and forget bullet expansion] The nice people at LEE precision make a bunch of very good 6 cavity moulds in 45acp for a very good price. Made out of aluminum to keep costs down, the mould heat up fast, make a decent cast bullet and are good for producing big quantities. I recommend their 6 cavity 200 grain SWC. Behind 4.0 grains of PROMO, this is a target quality bullet.
Go to the LEE sight and look at their cast bullet chart.
