22 conversion kits

I also bought a box of .22LR 'Aguila' Super Extra [with label on box 'Eley Prime', whatever that means], 50 rd box @ $5.00. He had one brick of that come in from distributor, and a brick of .22 Subsonic ammunition, that looked like a .22 short with a real long bullet. I didn't think that would work any .22 action I have, so I left that alone. (I don't have any bolt action .22's or revolvers).

I was thinking that the Erma barrel inserts are longer than the Luger barrels because it would take longer to build up the pressure to toggle the action than if they made it the same length as the Luger barrel...

Dave - Does your Erma toggle have a model number on it??? This one says 'SE 08/2'...

Edit: I went back and bought a box of the 'Sniper Subsonic' .22's...Looks like a .22 short to me!!!

(And in the 15 minutes I was gone, someone came in and bought the rest of the .22LR brick)...

This is the first time I have ever seen a subsonic cartridge with a bullet like that. I have a couple of different brands of subsonic .22 ammo here, and the bullet on them looks like a normal 40gr bullet. Interesting!!.

I think these slugs are around 60 gr., which helps diminish the velocity to somewhere in the vicinity of 1000 fps, + or -.

Ely is another ammo manufacturer. I think Aguila gets primed brass from them, or at least uses Ely's formula, probably under license. The various ammo makers' arrangements and manifestations seem a bit incestuous at times...

Since bullet and case of any .22lr share the same O.D, it should be no problem. It's the OAL that matters; I'm presuming that where the cone/taper/roundness ends on of all of their bullets is engineered to appear at the same distance from the rim, and thus will all fit in the .22lr chamber.

Nope, just "Erma" in a circle on the breech block. There is a groove in the top surface of the front toggle link which precludes placement of anything stamped there. Mine is the SE-08 model, immediate precursor of yours, and they are both post-war in vintage.

Ed, the Mini-Mag data on this sheet is for the HP, which my pistols don't seem to like, failures to feed. Different muzzle velocity than the CPRN, too--a bit faster, 'cause it's a 36 gr.

Yes, that is what it says on the box. The bullet itself feels and looks strange; like it has a plastic sheath on it...

I had always thought that rimfire primer was just mixed & poured around the circumference of the shell, but reading on another site, they said that the primer is a string/ribbon coiled along the rim of the shell...

That kinda makes sense. I've taken apart old British .303 cartridges and was fascinated by the cordite 'rope' in each cartridge...Seems easier to manage, just measure a length & cut it and stick it in the case...No weighing!

That's what I remember from taking them apart. The primer seemed to be a dried green crust down in there. Forty years ago I survived the task of scraping it out of a bunch of cases, and the resulting powder, along with the gunpowder, guts from a bunch of small firecrackers, and some crunched up match heads, inside one of those little Bayer aspirin tins, bound up by an entire roll of masking tape, made an interesting device to light and toss out the dorm window, for sure.
(Also prepared a batch of ammonium iodide, which was a blast [pun intended]! The best one, for the show of it, was a small oil can full of equal parts, IIRC, sugar and saltpeter, with contact wires to a broken flash bulb imbedded therein with its filament exposed, and the spout of crimped to hold the wires. The entire device disappeared, and some of the guys in the dining hall reported the entire woods lit up momentarily by the flash, opposite the big room's wall of windows. No one hurt, nothing damaged, fortunately. Amazing how the young mind amuses itself...)

Here's a couple pics of the SE 08/2 Erma 9mm 4"bbl 'kit'...

Maybe some of the other owners could post pics of their kits (other than the 4" SE 08/2)...

(And a big 'Thanks!' to Ed Tinker for making this a stand-alone conversion thread!)

I read, way back when, in Playboy, that an acceptable version of napalm was 2/3 Duz dishwashing detergent and 1/3 gasoline, in a glass wine bottle, with a Tampon taped on the outside...A home made 'Molotov Cocktail'...Haven't had the urge to try it out yet...

The nasty nature of napalm is that it will stick and burn. The dish soap would make it sticky for sure, though I'm not sure if the mixture will emulsify. You could update the recipe by using Dawn, and clean off some oily wildlife with the excess detergent!

I think engineering schools probably contain the highest proportion of students interested in explosives. My brother went to RPI, and had a frat brother who was missing fingers from his high school days, when a timer malfunctioned on a device he was setting off in the Troy High parking lot.
