What unusual/nonstandard calibers do you load?

I load for a 6.5X220. AS the name implies it is a 6.5mm bullet in a 220Swift case. I started experimenting with this around 1980. I launch these bullets from a 14" contender with a 2X7 Burris scope.
 
Haven't seen this one listed yet:

38-55 WCF

Just started reloading it, still working out the bugs
 
Unusual?

.41 Mag (?)

.257 Roberts

.250-3000 (.250 Sav.)

.375 H&H Mag.
 
400 corbon which is a 45 ACP necked down to 40 cal. rather interesting in that it'll take in many 45 autos with a barrel and recoil spring change while all else, to include magazines, remains unchanged
 
7.62x54R is as weird as it gets 'round here. Son #2 got a Mosin Nagant and we did some work on it. With our 150gr Sierra bullets and a charge of BLC-(2) we are able to get 1" groups at 100 yards.

That is about as odd ball as I care to get. Wanna talk about some 45 Colt Linebaugh loads though, I'm up for that! haha :)
 
Only three that someone has not already mentioned:
12,17X44R and 8X58Rimmed Danish and 7X57R
One that only one other has listed:
7,5 Swedish Nagant
Ones that various folks listed:
32-20
44-40

Did not notice anyone mention 16X65, 16X67, 16X70, 12X65, 12X67

.44 Russian has been my limit. I'll be reloading 9mm Auto Rim (.38 S&W brass trimmed to 9mm Luger length) for use in my M649-3 Convertible once it gets back from its trip for modification.
 
I have about all non-standard: 38-55; 38-40 32-40; 32-20; 44 Russian; 44Colt; 44-40; 44 S&W Spl; 45 Schofield; 45-70; 30 Luger; 375H&H; 25-06; 32 Colt; 38 Colt; 41Colt; 41Mag; 9mm Ultra are some of my reloads. There are others plus the standard 9mm Luger, 38 Spl, 45 acp, 45 Colt, etc. It a great part of my hobby.
 
My most unusual reload is the 7mm-08 Remington.

The 8 mm Peabody Spoonbill. Parameters set fourth by Jeff Cooper himself.
 
.30 Mauser (for a Broomhandle), 7.62 Nagant (for a Nagant), 7.62x25 for Tokarev's and a CZ-52), 32 S&W (for several topbreaks) 38 S&W (for topbreaks as well as some 1970's vintage J frames, and a 1938 vintage M&P, (9 Largo, for an Astra and a Star), .32-20 (rifles and revolvers from an old M&P to a Browning 53) .38-40 ( for a Win. 92, Colt new Service and a Ruger Blackhawk), .44-40 (for a Win. 92).

8mm Lebel (for a Lebel rifle) 8mm Kroptaschek (for an 1886 Portugese service rifle), 8X50 R and 8x56R (for the Steyr model 95's), 11 mm Danish (Rolling Block), .43 Spanish ( Rolling Block), 7.5 French (MAS 36), 7.35 Carcano (for two ex-Finn Short Rifles), 6.5 Carcano (several carbines and rifles), 6.5x53R ( Dutch carbine made by Steyr), 8x52R (Siamese Mauser), .25 Rem, 30 Rem. 32 Rem ( For Rem. Model 8's), 7.65 Arg. ( Belgian, Argentine and Peruvian Mausers), 6.5 Jap and 7.7 Jap. (Arisaka's).

I am sure there are others. I didn't include stuff like 8x57, 7.62x54R, and some others because its not really odd anymore. Not like it once was.

My first experience with weird calibers was 7.62x39 for an SKS a relative picked up in Vietnam. There was no ammo available commercially so I pulled the bullets from 7.35 Carcano Italian military ammo and formed the cases by moving the shoulder back, upsizing the mouth of the case and modifying the rim. Back in the early 1970's there was a glut of 7.35 ammo dated 1938 and 1939 so it seemed easy enough. Of course since the brass was berdan primed and and an odd sized berdan primer to boot, it was only good for one firing and in those days I had to use what I had. Those 7.35 bullets were used years later to load ammo for 7.35 that I formed from 6.5 MS or 6.5 Carcano brass. I still have some of those pulled bullets but I mostly use cast in the 7.35's just for plinking, but I have also swaged down .308 and .310 SP's for hunting.
 
Depending on how you define "unusual" or " non-standard"==I'll just say these are ones that I have found empty slots at gunshops-IF there is even a space for them. Most have been named already.
