Anyone who has ever shot the old standard Remington 158 grain lead semi-wadcutter knows that it was loaded with a soft lead bullet. 50 rounds through my S&W M27 3 1/2" resulted in the barrel looking like a smoothbore from the lead stripped off & left behind.
Old Elmer always pushed for a moderately hard Keith SWC, especially in magnum revolvers. Swaged soft lead bullets are much cheaper to produce though.
