But, also right, they can't hit crap with it.
Anyway, that's what the official survival thinkers thought, so enter the service auto as shotgun:
Approach No. 1, left, is a straightforward loading of tiny shot in a cardboard capsule, heavily crimped with two grooves aft of the case mouth. The point is to preserve the sharp mouth on which the round head spaces. This example is head- stamped Peters .45 A.C. (no "P")
Concept No. 2, center, employs a redesigned case, longer and necked to provide space for the shot. The seal appears to be a waxed or plasticized cardboard disc. The shoulder is abrupt, but still a long way from a precise, tight fit to the chamber stop, and I have a feeling that the engineers were in a bit of a hurry and decided, what the Hell, the extractor will hold it well enough; heresy but most probably workable. This one in head stamped "R A 4."
We'll get to survival round No. 3, right, in a moment, but first an editorial comment on the others: I suppose that if I'd dumped my Corsair in a Samar jungle I'd rather have had a handful of official government shot shells than not have them. On the other hand, I wouldn't have put a lot of faith in their (and my) ability to get me fat on the succulent Basilan flying squirrel. Or much of anything else. Anyone else who has wasted too much time playing with shot loads adapted (maladapted, to be correct) to rifled pistol barrels understands. About the best you can say for the entire line of thought is that if your stalking skills challenge Natty Bumpo's, you might kill something small to eat once in a while.
And now to No. 3. It IS TOO a survival load. It helps you survive the dreaded feeling, "What on God's green earth am I supposed to do with this junk I found while tidying up a shop cabinet last opened before Monica stained her dress?"
Why, I confirm that they'll actually go bang in an old .22 bolt gun and then I'm all like, hmmm. I know, I can glue a .22 Crossman pellet to the front of it and have my own wildcat! The .22 TMR Power Load Special.
I was crushed to discover that I had no .22 pellets but, unstoppable, I subbed a Daisy BB. Even though the prototype you see is the only one in existence, it will soon be tested with full confidence that the .177 projectile will exit the barrel.
Further than that deponent sayeth not.
