Re: 38 super rounds?
The .38 Super (Automatic) is a totally different breed of cat than the .357 Magnum. Ammunition is NOT inter-changeable between the two. If you mean "Can I use 80 grain cast LEAD bullets intended for the .38 Super for reloading the .357?" the answer is 'yes'. but.... you need to find a source that will give you a safely tested powder charge.
According to my Lyman reloading manual, cast lead bullets for the .38 Super should be .355 to .356 diameter, and those for the .357 should range between .357 to .359.
So, just for the sake of an arguement, if you have cast bullets (unsized) for the .38 Super that wiegh 80 grains and mike out at say - .356 or larger, you could manage to load those into a .357 Magnum case. You'd have to find a source for a safe powder charge, because the lightest cast bullet in my manual calls for the same 92 grain cast bullet in .357 Magnum and .38 Super.
