Can this be true? Can it be so soft that it doesn't have enough resistance too swage the jacket to its full size/profile?
Possibly squeezing by the core seating punch instead of filling out the jacket.
Most range scrap that we collect isnt dead soft lead. Ive gathered range scrap that was 99% core lead from jacketed pistol ammo and it doesnt seem to be as soft as this old pipe lead I found with my metal detector.
