A .38 Super may chamber as the case is a semi rimmed and not rimless (like the .32 ACP/7.65x17 Browning). I've fired a .38 Super case out of my .357 Mag Contender. Also the bullet will be undersize as the .38 Super uses .355" diameter bullets @ 36,500 PSI and the .38 S&W case generally uses a .360" dia and pressue is 14,500 PSI. However if it chambers do NOT shoot the Super in the old .38S&W.
