Chev & Slumlord,
I've been following this thread . . . . . . . . . . . way....
Chev - I've been collecting the dies & tools to make rimfire cases from .22 Hornet brass. Got the .25ACP carbide sizing die & .22 reamer but grateful if you could expand on use of the the primer pocket swaging tool in the process. Sounds a lot easier than cutting down the forward edge of tcase rim. Thanks.

Spud,
The RCBS Primer Pocket Swaging Tool Kit contains several items that I use as part of the .22 Hornet case reforming operations.
These include:
1. The Small Pocket Swage punch, which fits on the Press Ram in place of a Shell Holder.
2. The stripper cup, which goes over the punch and surrounds the top of the press ram, it is intended to 'strip' the swaged case off the end of the punch at the bottom of ram travel.
3. One 'SAE 3/16" nominal Inside Diameter "Fender Washer', which goes on top of the Stripper Cup to limit the punch ingress into the case head when doing the final portion of head Swaging/rim Coining.
4. In addition you will need a long "pin Punch" of about 3/16" or 7/32" diameter of sufficient length to allow 'knocking' the Fully swaged/coined case out of the Sizing die.
5. Also a 'suitable weight' hammer to use with the punch.
The Press used should be strong enough to allow forcing the base of the cartridge into the Sizing Die all the way to the Rim, as a minimum, and preferably also Coin the .070" Hornet Rim down to Stevens .050" Thickness.
An RCBS "JR-3" Press is the minimum to form the Base (repeated incremental adjustments of the Sizing die are needed to size the base, involving multiple 'top of ram movement' cycles to complete each case).
An RCBS "RC" Press is the minimum that will also Coin the Rim to Thickness (I have done it in one cycle, but find two or three repeats are more consistent, the die is NOT adjusted once the proper .
