Just back into reloading/casting after a 2+ decade break.
I am loading for both .38 SPL +P and 9mm Parabellum; for plinking - carry ammo is all corbon
I know simple WW alloy with a little added tin is fine for the .38 wheelgun, but what is suitable for the 9mm?
Can I get by with quenching the ww casts, or do I need to heat-treat - or go to a harder alloy?
The resources I have disagree widely about the necessary hardness/strength for the 35,000 to 38,000 PSI 9mm loads.
Can someone answer this for me?
Thanks!
