It seems someone has capitalized on the idea.....
www.jkmshells.com/ (http://www.jkmshells.com/)
Add a shotgun primer and a .22 pellet, and reuse the shell.
Wouldn't lead pellets cause lead build up in the barrel?
Any other thoughts>?
-
Not sure how accurate that setup would be.
-
I'm not either... seems like an AR (for the .223 version anyway) would have a very fast twist rate for a pellet
-
pellets are .005 to .008" smaller than a .22 barrel so they will not be very accurate. Go ahead and try it and give us a report.

I have no intention to... I don't own a powderburner and probably never will, but I was just curious. There isn't much around about it, though.
-
I'd like to know the legal issues behind this myself. Certainly not an air rifle.
Charles

I think it would count as a powderburner, because it is..
-
Factor in the additional risk in handling shotgun primers. (Yes, there IS a risk - read almost any reloading manual.) I have seen cartridges which utilize a primer and wax or rubber bullet for larger calibers, but not .22's. Most of those try to use .22 rimfires in a conversion casing. That idea has been around for ages. Pellets just don't seem to fit well. Pedersoli has a little break-open that uses shotgun primers and small shot but, frankly, it's kind of a high priced joke. I seriously doubt these will do better (and that ain't saying much.)
-
I wouldn't think the lead pellet would lead up a .22 barrel any more than a lead .22lr round.
I don't know that you could really call it a powder burner either, as what is in a primer isn't really powder. Gun powder doesn't go off if you smack it hard (what the firing pin does to the primer), whats in the primer is some compound that explodes when smashed. I'm not a chemist, so I can't say what is in there. I do know that at some point primers contained mercury, as they sometimes throw in mercury free primers in the advertising.....
-
Would this idea be similar to the Daisy VL?
Nathan
-
Kind of. But it uses existing primers and a reloadable case fired from a real gun instead of everything dedicated to the VL system
-
I don't know but I'm certain a regular airgun would be quieter than that set-up. I've shot at a shotgun primer with a pellet in my basement and the "Bang" was alot louder. The only other times my airguns were louder than a .22lr cartridge going off is when there's detonation.
Btw....don't try this folks....the primer from the empty shotgun shell flew back (Didn't know they did that....) and struck, broke skin and bruised my left wrist. Two or three inches higher and I would've lost an eye!!!! I have a tread in the "Old GTA" with a photo of the damage.
-
Sounds like those primers can be dangerous!
-
They are. You'd think they put off a spark, but they put off a mild explosion. Really loud if primer isn't in a shell..
-
Please, no talk of shooting primers. This has been discussed on several forums and is, basically, dangerous. Primers can be dangerous to handle and fragment if exploded outside of the cartridge/gun they are intended for. Inside most primers is a little piece of metal called an anvil that the firing pin strikes to ignite the priming compound. In an unsupported primer, the anvil has been known to blow back.
These gizmos do not turn a firearm into an air rifle since they don't use air to propel the pellet. They are closer to .22 CB cartridges.
-
I think these have an edge in velocity over .22CB but that's because they're lighter... but still not too useful

I know it's dangerous. I did it once, never again

For what it's worth, the compound contained in modern primers is lead styphnate.
The old ones contained mercury fulminate.

Shotgun primers have enough force to do some serious damage. They have enough force to push 1-1/8 oz of shot and wad out 25-30 yards with squib loads (a shotshell accidental reloaded without powder)
I reload for trap and skeet. Sometimes you get a bad, or crush a hull while reloading. Pressing the new primer out to reuse it is very risky and I don't like throwing a live-primer hull in the trash.
I safety bad reloads by firing just the primed hulls in one of my shotguns. I've had sparks come several feet out the end of a 12 gauge barrel. And shotgun primers are as loud as a 22 rimfire.
Then there's the shrapnel.
As RedFeather said, inside each primer is an anvil with pointed corners that can and does sometimes come out. In addition, primers have a disc inserted in the open end to keep dirt and moisture out. That disc comes out every time and can do some damage ricocheting around.
And burning powder is often not the only determining factor. Some States and local laws use the term "firearm", not "powder burner", because there is "fire" causing expanding gasses to propell a projectile. Primers are considered part of what makes that fire. Firing a shotgun primer in a gun where discharging "firearms" is illegal will very likely get you in trouble.

There seems to be an unending supply of idiots who design ridiculous, unnecessary items for all the other idiots that will buy them. An $80 springer will probably out shoot these things out of the box, and be more cost effective because you won't be buying his modified casing(w/2 dimples in it) for $18 bucks and additional $$$ for the primers. Of course, you'd miss the experience of the AH-HA moment you'd have when you realize that you had made an idiotic purchase. ;D ;D ;D

This is a more elegant solution to a primer power pellet rifle, but still not worth it considering the ARs available in the same price range.
-
That is the doofus gun I was talking about. Elegant, perhaps, in the way that Winona Judd is beautiful. For $350 you can do a whole lot better with a small caliber muzzle loader that actually is a gun. Might as well, since that Pedersoli will be in the same class, legally, most places.
-
Might as well get a marlin or ruger .22....
-
My $.02... Centerfire is just that, a firearm. I would not encourage the next generation of air gunners to experiment with primers of any size. I have a friend that lost 4 fingers and a thumb and partial loss of one eye playing with a blasting cap, thinking it was harmless without the Dynamite. Granted that's alot more energy that a primer, but that one mistake changed his life forever.
-
Primer Follies. Got to CCI or another home page and look up the safety rules for primers. I once posted them on the Yellow and they sobered some folks up. Primers are not cap pistol ammo nor are they percussion caps for muzzle loaders. Mishandled, you can get primer cap chain explosions, etc, with all of the associated burns, missing digits and shrapnel. Why they make primer sorters and other safe handling devices.
Back on topic, this is not a new concept. Sort of like taking a BB or CB cap and deconstructing it, which is to say going back to around 1850. Why bother? What you will end up with is a firearm, so best check your laws.
Oh, and one more thing just came to mind. If you are using these in a firearm, best be sure that the pellet actually left the barrel. Othewise, the next time you load some full house ammo, Hasta la vista, baby!
-
Since I actually shoot an AR-15, I can see the appeal of a set-up like this. You get plenty of trigger time for practice without burning through 5.56mm ammo at 25 cents a pop, and can practice in your basement or garage, something you can't do with a .22LR upper conversion kit. It would really appeal to those in the AR-15 community that either shoot competitively, or are practicing because they feel there will be a &^^&-hits-the-fan event in the near future when they will need to rely on their firearms for survival.
-
How accurate do you figure that will be, given the twist of your AR? Cumbersome for a long session, as well, plus you will need good ventilation. And special attention to pellets lodging in the barrel.
As to the "balloon going up", etc. If that ever does happen, at least where I live, making every round count isn't going to be a problem since I doubt I will be around to squeeze the first one off.
-
Why won't this subject go away??? Is it because the subject is stupid?. Or is it because it is dangerous? As Stated , primers are not toys. They are dangerous. Especially when not handled properly. The idea of knocking a primer out of a shell, any shell, and inserting another inorder to fire a .22 pellet shows someone is not thinking seriously. People that reload ammo use presses and dies designed to accomplish this feat. To try and do this by hand using who knows what is just asking for a serious injury. To yourself or someone nearby. Make sure your health insurance is paid and up to date as I don't want to pay for someone's stupidity . Heed the advice of others. This is a bad idea.

Yeah, it's getting to be long in the tooth. The original post was about a cartridge that takes a shotgun primer and pellet for use in powder burners, so they weren't suggesting knocking out primers (really, really BAD idea, BTW) or such. Midway has 209 primers for between $27 and $47 per 1,000. So it's not that cheap if you shoot a lot.
-
Redfeather, I didn't say I didn't think this is a GOOD concept :-) The accuracy would probably be horrible, and reload time would be a PITA.
