A friend did this and I'm also going to try it.....
Take an empty 223 case (or 222 as well) and poke the primer out and install a new primer.

Dent the case neck very slightly so that installing a hand pushed 22 cal pellet from a pellet gun will just stick in the case neck.

This powderless round has accounted for a very large number of starlings and other (crats) small pests in areas where quiet is good.....you can be your own judge as to where this is.....one can even shoot them in your basement.

He clains dime size groups at 100 yards on quiet days and shoots starlings at 60 yards with errie consistancy....

What an idea!!!!!

Hey VapoDog, If I were you, I'd take some money with me to the Range, lay it on the bench and bet he can't do the Dime at 100yds. I'd also bet Starlings at 60yds are about 35yds too far away.

I'm not disputing he told you that, just have doubts about him being able to duplicate it.

Reason why is I used to do that with a 22Hornet. In it you punch out the Primer, do a Full Length Resize "without" the Expander in it and then screw the Expander back in to open the Mouth for maybe 3/16" down the neck. This creates a Shoulder to keep the Pellet from falling on into the Case.

But, when you get to the 3rd Primer Powered shot there is so much Primer Residue in the Bore that the Pellet "Hangs" in the barrel.

Obviously that meant more Fuel was needed and I used WW-231 starting with 0.4gr. I believe by the time I got to 1.3gr-1.5gr the Pellet Skirt was being blown off because the Patterns got even larger. And the loads were very "Powder position Sensitive".

Even tried Promethius Pellets which has a Nylon Skirt and a Zink Core (shaped somewhat like a shuttlecock).

Since the Hornet case is significantly smaller, I'd guess the Residue would be even worse in the larger case.

Try a few and let me know if you can get the 4th Pellet down the barrel without it hanging. And let me know what kind of groups you get at 25yds. Maybe the CCI Primers I was using were just too dirty burning.

It is an interesting exercise.

I shoot a lot of cb longs dime size at a 100 feet A hundred yards I dought it. I sure it can kill starlings put the distance seems way to far.

hi
Stick half a felt cleaning pellet in first,or blob some epoxy in the skirt

Many crows have died in the sub-urbs due to CBs in rifle with trajectory dialed in for that tree ~100 feet from the open window.

They fly 15 feet and then collapse.

Silent death by CB body shot, much more effective than the 177 break action pellet gun, that needs a head or neck shot.


The reason you want CB shorts and not CB longs is the same reason you want nothing to do with .223 silent loads: expansion ratio. Get the peak pressure up and get the muzzle pressure below 2 atmospheres.
