The battle of the bulge...

Post by Multiracer on Thu Sep 06, 2018 9:22 pm

First topic message reminder :

So, revolvers, model 52's and some 357's shooting 38 special loads.
What tool is out there to make these cases straight walled again ?
Or.....is it of no consequence to see these cases bulged a bit near the base?

A swaging die in a press with an internal case ejector, preferably hydraulic, will serve your purpose. Make sure you use lube. Will probably reduce case life and create head separations due to working the brass, but, should meet your requirements.

Greetings,

"A swaging die in a press with an internal case ejector, preferably hydraulic, will serve your purpose."


I machined a similar device. The "shell holder" is open the depth of the case rim.

The sizing die is screwed down flush to the shell holder.

During the press stroke, the case is pushed all the way into the Carbide ring flush to the rim.

On top of the press is a steel tube containing a steel decapping rod and two Corvette valve springs.

The springs have enough energy to push the case back out of the die.

Been using this to size 32 S&W Long, 32 ACP, and 38 Special for many years.

After wet washing with pins, the cases are hard to tell from new.

Oh yes, no head separations. Just the usual mouth cracks from age.

Cheers,

Dave
