The standard military .38 Special load is a 130gr FMJ.
Different sources give different velocities, one says 810fps, another says 950fps.
Ok, did a little digging, and a 94 headstamp round should be approx. 950fps.
There was a lower velocity round made to support the aluminum cylinder (& frame) "aircrew" model S&Ws and Colts, as the standard load was too much for those guns. Those guns were retired from service rather quickly, and the light load M41 ammo went away, the load returning to what it was originally.
Reportedly the 130 at 950 has the same POI as the 158 at 850 (or close enough to be usefully "on" with the usual fixed sight set up).
What U.S. military coppers, assuming it's MP's, were still carrying .38 revolvers in 1994? Just curious.
The military still have, and issue .38 Specials. Not for combat use, or regular aircrew use, but for MP use during prisoner transport duty. (they were doing it in 94, I know the Air Force was still doing it 2 years ago, and I think they still are). I'm told all the services agreed on the .38 revolver for that use, some time ago.
A 130gr FMJ with a WCC 94 headstamp is Winchester produced ammo for military use, in 1994. It might have gone to the military and later made it way out (surplus, etc) or it might have been sold direct to the public, as "surplus" (contract overrun, etc.)
No way to know which.
