Johnny's Reloading Bench conducts a torture test on Shell Shock 9mm casings, pushing them to extreme +P+ pressures in a Glock 19. The casings, made of nickel-plated aluminum with a nickel alloy stainless steel cylinder, demonstrated remarkable durability, outperforming brass and lasting through 11 firings before a split occurred near the base due to extreme pressure. The test highlights the need for specialized S3 Reload dies with a unique spring-ejection system for these two-piece casings. This expert analysis provides valuable insights into the performance limits of advanced casing materials under high-stress conditions.
