anybody ever reamed or swaged a primer pocket from a small pocket to a large pocket?

any suggestions for tools or method to do this?

thanks a bunch

Actually, no I haven't, but I have seen where some cartridges I load for have come in either persuasion. The 7.62 x 39 for one. Also years ago at the SCi convention while dallying away the time mooning over a .454 Casaul (sp?) I noticed that they had niffty little bushings which would change a large primer pocket to a small primer pocket. Their purpose was to go from large pistol primers to small rifle primers in their loadings. Quite neat actually.

Yes I have. They started out as Berdan primer pockets and wound up Boxer primer pockets. These were on Carcano military brass in the early to mid 50s.They had the cutest eliptical flash holes you ever saw, baring anything human. Necessity is the mother o------------- roger
