Well guys this is the second time I am trying to type this, the first went to never never land in cyberspace. AND I am typing on a small old laptop since my old desktop finally gave up the ghost.
I have decided to post this here because it is built around a centerfire receiver (or you could use a shotgun reciever).
I just recently received my new carrierless primer holder for my Huntsman and tried it out with the only shotgun primers I had on hand right now, some old Remington #57's.
They worked but as I looked at the fired primer I got to thinking, and that as we all know can be a dangerous thing.
The fired #57 shotgun primer looked like a short .22 cartridge with a primer in the center, Hmmmm, very interesting...
Out comes a .22 LR Sportster and in goes the fired primer, except for learning to be careful to prevent the primer lip from getting under the ejector lip when laoding it fit well and then ejected fine.
Step 2, now it gets more interesting, take the .22 rimfire barrel off it's frame and try the barrel on a couple of rifle frames and a shotgun frame, it would not lock up, but I have a "few" more frames to try it on. Thinking of the experiment that Larry just did by firing his 32-20 with no latch installed gave me confidence, and this was only a primer right?
Here I go, I loaded an unfired #57 Remington Shotgun primer in the .22 LR barrel on a centerfire (or shotgun) frame, pointed it in a safe direction, and pulled the trigger.
BLAM!!!, about a foot of white flame coming out of the barrel. What a great noisemaker and what a great show at night... and by the way, the fired primer ejected great...
BUT, as they say on TV infommercials, Wait!!! There's more!!!
now for the good part, or the crazy part. My mind is reeling with ideas, how about loading a .22 caliber lead pellet ahead of the primer? A primer fired pellet gun. I have saved some fired .22 Caliber colibri bullets I have recovered, I may even try those.
I do not know if there is a brand of 209 Shotgun primers that may fit in a .22 WMR chamber but I would sure like to find out which 209 primer is the smallest diameter.
What I have found and done is fire a #57 Remington shotgun primer in a .22 Rimfire Sportster barrel, mounted on a Centerfire (or shotgun) frame. A true Frankenrifle, comprised of rimfire, centerfire, and shotgun compatible pieces, and now I am going to get some air rifle .22 caliber pellets to complete my creation..
Remember, have fun and be safe....<><....

P.S. - is this a sign of cabin fever or just a warped mind?.....never mind...by the way, did I ever tell you about the zip guns and rocket lauchers/bazookas I would make as a kid? Powered by my own home brewed black powder of course...
