The shape of a 230 grain being what the .45 Auto was designed to function with, they are a real good choice to use inasmuch as there are fewer problems (with function), using them than other designs. If you load them to the over-all length of factory rounds and use a powder charge that functions the action smartly, you will have few (if any) problems.
RCBS makes an excellent 230 RN double cavity mould that I have used (along with their excellent semi-wadcutter .45 auto design).
