As said above that is the 200 gr. "Super Police" load. 200 gr. is really too heavy for .38 Special resulting in very poor performance and low bullet energy. I still have a few of those rounds that I have had since the 1960s.
This is from my chronograph records:
In November 1995. I shot them over my then new Oehler 35P chronograph. Distance to the screens was 10 feet. I fired two sample strings of, 5 rounds each from a 5" M&P. The average muzzle velocities for the two samples were:
#1, 635 FPS avg.
Extreme spread 104 FPS
Standard deviation 34 FPS
Energy calculated 178 ft. pounds
#2, 621 FPS avg.
ES 192 FPS
SD 49
Energy 170 ft. pounds
I don't record individual shot velocities as they mean nothing.
As you can see velocity was quite low and ES and SD figures quite high, indicating severe inconsistency. This load is "Super" in name only.
At one time Winchester loaded the same bullet in the ,38 S&W, also called the Super Police. I have never seen any of these. I hate to think how poor the performance of them was!
On the same day, same conditions as above but a different 5" M&P, I fired a hand load of the Lyman 358430, nominal 199 gr. round nose that basically replicates the Winchester Super Police bullet. Load was 3.9 gr/Unique, Rem 1 1/2 primer, sample again only 5 rounds. This was added just for your curiosity! Results were:
692 FPS avg.
ES 55 FPS
SD 15 FPS
Energy calculated 212 ft. lbs.
