I while traveling I took my reloader press but forgot my roll crimp. I load 2.5" shells with BP and lubed fibre wads. With no roll crimp I decided to put the over shot card on and then do a start star crimp in my Mec 600. It left the mouth of the shell quite open but the starter crimp securely held the over shot card. It worked just fine except I would not want to juggle the shells around in my pocket lest the over shot card give way and kept them in a container that holds each shell by itself. There was noticeably less recoil and from what I could discern and perhaps a bit more spread in the pattern. Has anyone else tried this? I'd like to hear how they handled the shells and what results they were getting.
