Does the headstamp read ".38 Colt" rather than .38 Short Colt?

I've used .38 Short Colt in .38 Smith & Wesson chambered revolvers with perfect satisfaction. Neither round gens up enough pressure in today's loadings to run amok. The .38 Short Colt uses a lighter bullet than does the .38 S&W (125 grain rather than 146 grain). The .38 Short Colt may be a thousandth or two smaller in diameter than the .38 S&W but it still won't matter for firing purposes.

There once was the .38 Short Colt and .38 Long Colt. At least Remington has still loaded the .38 Short Colt in recent times. I have a box or two.

The .38 Long Colt is close to .38 Special in length and won't chamber in short cylindered guns made for .38 S&W.

There was once a .38 Colt New Police which was only a .38 S&W with a different bullet design. I think I have a few rounds of ammo around here, loaded with lead bullets with a flattened nose and marked ".38 COLT NP."
