In my much younger days, I got hold of some .38 Short Colt and shot them up in my .357 Blackhawk. No problem forcing a .375 bullet down a .357 bore in that one, but then, a Ruger Blackhawk is pretty much of a tank, and .38 SC is pretty wimpy. My dad also had a .38 S&W breaktop(no name stamped anywhere on it, looks like a copy of an H&R). He THOUGHT that .38S&W and Short Colt were the same, so we shot it with both. Gun survived just fine, but not too accurate with SC. But the factory Short Colt rounds have very little bore diameter surface on them, the ogive started just in front of the case, not much lead to swage down.
Of course, now I know better, won't try either combination again!
