Original .22 short?

[ZVP]

Does anyone know the spec's for the origonal .22 short?
For comparisons sake, I clocked my Berettia Model 21 Bobcat .22LR @ 950fps with a 40gr lead solid.
I wonder how the old S&W compares to that? Has anyone chronied a Model 1 S&W?

I just bought one. Berttea 21-A I shoot CCI Stingers. Wonder what
they go.

If you're careful you could pull a bullet, replace the smokeless power with Black Powder, I'd guess 3F but I'm not sure, replace the bullet and see what velocity you get.

I don't know what the velocity is but it will put a small dent in pine bark from 10 feet.

IIRC, it was 1.5 gr of fff under a 29 gr externally lubed heeled lead bullet yielding about 600 fps.

IIRC, it was 1.5 gr of fff under a 29 gr externally lubed heeled lead bullet yielding about 600 fps.

That sounds plausible. A 29 grain bullet going 600 fps has 23 ft-lb of kinetic energy.
A rule of thumb that I have developed from studying black powder velocities is each grain of powder generates about 15 ft-lb of energy and that fits the 29 grain bullet at 600 fps almost exactly.

The 15 ft-lb per grain of black powder rule of thumb is not a hard and fast rule. Revolvers typically only deliver around 10 ft-lb per grain of powder. Large bore rifles and muskets may deliver as much as 17 ft-lb per grain of powder.

CotW says the .22 Short was loaded with 4 grains of fine black and a 29 grain bullet.

I don't know of anybody doing any shooting with BP Shorts but there are a few experimenters in .22 Stevens Long (.22 LR) with 4.5-5 grains of FFFFg or Null and 40-45 grain bullets. They are getting up to 1100 fps from a rifle, just like standard velocity smokeless.
