Just curious but why are you interested in expansion? Are you going to hunt with your 9mm?I cast 147 grain hollow points from the MP mold. It finally got dry enough to powder coat do I powder coated, sized and loaded 50 to test. Green is air cooled wheel weights and red is soft lead. Going to shoot a water tank for expansion testing and 30 yards to see is the soft lead makes fliers.
I used to reload Combloc cases in the late sixties and early seventies with Berdan primers. RCBS made a tool to take them out and we used a home made rig for setting them. It is a tedious process. Our cases at the time were brass. Steel will probably be harder especially when it comes to sizing.Rooted through my "non re-loadable" Berdan cases (I have a lot of them) I keep them for things like action proving dummies, "Master Cases" & so on.
A friend got a little "Indublienated" & bought a butt tonne of primers for Berdan!
Described as "large", not sure which "large" (there are 2).
I found a couple of hundred S/A R1M3Z (A-80 & A-81)
& almost 400 Brit made (G&B) once fired cases.
I offered them to him if he can figure out which EXACT size he has.
The rest will remain for things like action proving dummies, "Master Cases" & so on
Good for you!AFIK none of these cases are steel.
We are reloading .303 British.
That was the RCBS tool to remove Berdan primers. In later years, I learned how to do it easier and faster but it could make a mess. In that method, you fill a case with water, put a close fitting dowel in the neck and hit it with a hammer. The hydraulic pressure pops out the Berdan cap.Was that the giant "claw" thing?
I hated them.
I had one & gave it away to someone I heartily disliked because he was A PITA of major proportions.
I now discover there are not just 2, but 3 "Berdan" primer sizes? 1 "small", one "large", & yet another, "Larger than large"!
I guess I'm not dead yet as I'm actually still learning things!
One thing that I've come to learn about reloading is that there's so much more to learn - I'll spend the rest of my life learning new things.Was that the giant "claw" thing?
