if that did indeed happen I figure the expansion and likely case split lowered pressures drastically. The bullet would have been in the cylinder throat and be propelled out. Gasses sure could have been hot at the recoil shield but I can't think of any real damage other than gas blowing. I can't imagine not catching it on the reload. That is the only confounding thing, even for a non-enthusiast. Should have noted something afoul, but you never know.

Not as drastic but I NEVER would have caught it, fired .44/40 in a .45 Colt. Cases looked perfectly like .45 Colts. I just happened to remember I did not load any .45 Colt SWC that time. I even re-sized the .44/40 cases back into .44/40's a continued to use the brass.
