Lyman M-Die

[Seedsntrees]

Anybody using the M-Die with jacketed bullets?

I know they were designed for cast, but do they have any use for seating jacket bullets?

Thanks

The M-Die is designed to flare the neck of the case so you don't shave material off cast lead bullets. About the only use for M-dies with jacketed bullets is if you don't want to chamfer cases after trimming. Using one in a progressive press during a seperate case prep sequence allows one to speed up the case prep process.

Straight walled cases, either rifle or pistol, need a litle belling reguardless of bullet make up and the M-die works great for this. Otherwise there is no need to bell as the other poster noted.
