[QUOTE="Philip J Theodhor, post: 1781076, member: 111223"] I've found that you can repair a dented case mouth by hand just by inserting the expander mandrel into the cases mouth. It only requires a tiny bit of pressure to bring the case necks ID back. I also found that even when using the Sinclair expander mandrel #749-001-183 in my .30 caliber chambered rounds you really do not need but a very slight pressure on your press handle in order to expand the ID by +.001". So I myself feel very comfortable using the Sinclair Steel Expanding Mandrels and IMHO can not justify the added expense of a carbide mandrel even though as a retired Tool and Die Class A machinist I appreciate the labor intensive costs incurred during the manufacturing process.
