This may be old info. I had a RCBS 2000 which used the same shell plate for 38 WCF, 44 WCF and 45 S&W. Neither the shell plate for the WCF cartridges nor the .45 Colt plate will work. Hornady charges around $150 for a custom plate. I bought a #9 ($40) which is the plate for the WCF rounds and opened it up with a Dremel tool. It works well. Because of rim thickness, the #9 seemed a better choice than trying to modify a .45 Colt sheel plate.
