Mine likes RN bullets. Other bullet profiles may or may not feed.
Aside from that, it doesn’t seem to care. Lead, coated, plated, or jacketed. I’ve loaded anywhere from 185 to 230 gr. bullets (for the light stuff, Berry’s makes a 185 gr. hollow base RN that has the same profile as your standard 230 gr. ball).
I mostly load .45 with Win 231, but there are lots of powders that are appropriate for that cartridge.
The lighter bullets may run a little slower ROF, but not much. Maybe 50 RPM slower is all. Not enough to worry about, or to even be able to notice.
