Reloading roll crimp hulls

[Keith Doty]

Does anyone have an effective way to restore fired roll crimp plastic hulls for reloading? I have a fair number of spent ones but the case mouths are nasty and I haven't figured out a good way to restore them to "loadable" condition. Everything I have tried is labor intensive and not very effective.

I’ve loaded a bunch of once fired factory hulls that were roll crimped mostly in the 16 gauge but a few in the 12 . And I never had a great amount of trouble turning them to folded crimp . But I will say the crimp was NOT picture perfect but usable . I watched a YouTube video a week or so about getting fired folded crimp hulls ready to load as roll crimped . Guy was called “The Idahosian” or something like that . Anyway he made a steel rod that was a snug fit inside whatever hull he was loading and beveled the end going in the hull . After getting the rod inside the hull he’d use a butane torch to lightly hear the hull around the crimp area then turn the rod some and remove . In his video they seemed to come out pretty well .
