I acquired some ammo and there were a dozen rounds of this umc-rem ammo. There is not a lot of info on the web about it other than its 1930's or older. Before I put these down range, are they worth the hassle of selling?

I never heard of a caliber called "38 colt special" but if it is "38 short colt" or "38 long colt" then you can safely shoot that out of either a .357 magnum or 38 special revolver.

Now before someone else jumps in, 38 S&W is the one that cannot be fired in a 38special/357 magnum revolver. But 38 short colt /long colt yes.

if you have a revolver in 38 special then I say..... choot 'em!

The 38 Colt Special is the same as the 38 S&W Special except the slug has a flat tip instead of being round.

Yes, and it was around 1909 that Colt responded to the S&W Special. Here are a couple of photos...

Yep. That's them except it has a dark copper primer with a u in it. They worth anything? Or Sendem supersonic

They aren't worth much. Single rounds in very odd calibers or the old large bore rimfires will bring some money. Occasionally you find somebody who is trying to fill an old partial box or wants them for a photo shoot, but finding that person is probably more trouble than it's worth. I've been shooting some old stuff (some of them don't go bang, however!).

Worth nothing special unless you have a full box in good condition. Otherwise, shoot them. Several years ago I found a partial box (maybe 30 rounds) of 1930s era Winchester .38 Colt Special at an estate sale for a few dollars and fired them all. Chronographed MV was about where it should have been, around 800 ft/sec as I remember. All fired. Bullets have a flat point, like the .38 Colt New Police (counterpart to the .38 S&W) bullets.

"Now before someone else jumps in, 38 S&W is the one that cannot be fired in a 38special/357 magnum revolver."

Sometimes you can, with some brands in some revolvers. Same thing applies with .38 Super cartridges in a .38 Special or .357 chamber. Minimum spec case diameter will fit into a maximum spec chamber diameter. I have done it. I also have a friend with a Ruger .357 Security Six revolver, and its chambers will accept both .38 S&W and .38 Super of several brands.

Just saw this thread, don't know if you've tried to shoot these yet but those are some pretty old examples of the Colt load. The older copper primers with a letter stamped in them were being phased out by the late 20's/early 30's from what I've read. My own experience with trying to shoot up various old rounds of this era has been inconsistent. Some shoot okay, some not at all. The powder usually is okay, have pulled miss-fired ones down and re-primed with new primers and they shot just fine.
