I was just looking at an old Sportman's Guide catalog before tossing it
in
the trash. One item that caught my eye was a .223 adaptor to use a 209
primer to launch a .22 caliber air gun pellet. What kind of energy is
that
going to develop? What kind of muzzle velocity will that generate? It
might be a nice way to practice pulling the trigger and get some short
range
target practice with your bolt action .223, although I would be hesitant
to
use it in an auto.

The thing though is they advertise it for pest control. Seems to me for
short range even a pump air gun would be far more economical. As a kid I
killed a lot of gophers for the bounty with my Daisy 880. Spring piston
guns are so mush more powerful, and now with the gas spring guns on the
market for a few years you don't have to worry about leaving them ready
to
flip the safety and fire killing the spring.

Not even considering the PCP guns. How does this 209 primer propelled
.22
pellet compare to a pellet fired out of a pellet gun?

A "CB Cap", a small cartridge using the primer for propellant; using a
29 gr. bullet has a MV of about 725 ft./sec. Probably similar to the
adapter.

I don't think .22 pellets are anywhere near 29 grains. 11-13 comes to mind.

Somebody just needs to pull a bullet from a CB cap and put this to
rest.

I'll do that if I can find them. I still have a half box of CB shorts
around from my trap line days. At short range they would even punch the
skull of a badger.


I do know that Aquila makes two variations, one of which says "sans
poudre"
