Most Obscure Caliber?

[DRoberts12345]

I have a 37 x 85 shell and projectile. Sure wish I had the gun to go with it.

.22Winchester Auto for my dad's old '03.

10mm magnum is the rarest caliber I have, a close second would be 445 supermag.

You have an Automag IV? Neat, I once had one. I actually have owned or own a few of the guns chambered for cartridges mentioned. I've had chances to buy 357 Maximum Rugers and Dan Wessons but I passed.

5MM Remington Magnum

8MM Shotgun called a garden gun.

I think you mean the 9mm shotshell I think it comes in rimfire and centerfire versions. Unless there is an 8mm version I'm unaware of. Winchester made the model 36 I occasionally run across them. I have a Remington chambered for 22lr shotshells with a smooth bore.

As far as what I own, .32 S&W and .38 S&W.

These are black powder originally, and I reload them as such. I have purchased the .32 (pricey) in smokeless and see that SG Ammo currently has .38 currently available, but I wonder what modern ammo would do to these old top-break revolvers.

I had 20 rounds of 8mm Rem Mag, but never found anyone who owned such a gun. I ended up giving them to a fellow calgunner who said he could pull and use the projectiles to load for his Mauser.

I have dug up some casings around my place that appear to be .38 rimfire. Maybe one of these days, I'll dig up the gun.

When I find the odd box of 32 S&W for $15 or less on a gun show table or languishing unsold at a gun shop I buy it. I can always fire it in my 32 longs or magnums or my circa 1909 Iver Johnson. It is probably a black powder era gun but 32 S&W smokless factory loads are very mild.

I also pick up 38S&W when I see it cheap. My rule of thumb is when you see calibers like 32 long or 38 S&W priced similarly to 9mm Parabellum ball ammo buy it up. I picked up a pile of 32 long last year some as cheap as $9 a box out the door. I have a Enfield revolver I'm looking for a S&W Victory model made for Australia or England to keep it company.

Nothing particularly unusual, but the least common calibers that I own are .257 Weatherby (Mark V Lazermark) and 416 Remington Magnum (Winchester 70 Safari Express).

[I Swan]

Both those calibers are available on Gunbroker. When you can't find a cartridge on Gunbroker you know it is rare!

Another vote for 8mm Nambu.

[onelonehorseman]

22 short (black powder); first metallic cased pistol cartridge; used in the S&W #1 top break revolver ca. 1860's

Also, S&W 500 Special; Corbon made them for a while but it looks like they stopped.

No, he means 8mm. There are 9mm flobert primed shotshells for garden guns but, there are 8mm centerfire shotshells for other garden guns. I own a .22mag smoothbore Marlin garden gun and a Rem 121 .22lr smoothbore Routledge designed and marketed to shoot a clay sport called Routledge instead of being marketed as a garden gun.

Rounds for the piece in my avatar, .32 extra short. I have the arm, but no rounds.
