Hmmm I have never tried, but they are very adjustable. I use one to make 300blk cases from 223 and when I do that I from a lot off. If you had to you could probably reduce the thickness of the plastic insert that indexes the case as this thickness would seem to be the only limiting factor. I'm a little to far away from mine to check sorry but I have found the maker to be very fast at responding to emails so it could be worth emailing them
