The new Remington Plus P brass is heat treated for higher pressures in the .38 Super. The .38 Super invented in 1929 was a souped up .38 ACP and has used that old case even after Colt improved the chambers in 1988.
Huh? You can't heat treat brass to make it stronger. Anealing will make it softer. Brass gets work hardened.
In life, strive to take the high road....It offers a better field of fire.
