What unusual/nonstandard calibers do you load?

[Rule3]

Most unusual... this one.

25mm Hotchkiss/Puteaux round. Custom made dies and custom made solid brass projectiles. Each bullet approximately 7/8 pound [6125 grain]. Propellant charge approximate 1/3 pound [2300 grains]

Shoot them in the French Puteaux SAL 37 anti-tank cannon.

Picture of loaded rounds, projectiles.

Copper jacketed, steel core factory AP/T, first generation solid brass, base using .50 caliber bullet as tracer element, first generation w/tracer, second generation solid and short range "semi-wadcutter".

Also load 20mm x 138B for the Lahti anti-tank rifle and been know to load a wee bit of .50 BMG

Get outa town!! That is awesome.
Ding Ding! We have a winner here

What was that target in the picture??

 

[cjw3]

8x56Rmm....big tapered case, deep grooves, large chamber, funky action.

There has been a big learning curve with that one but I'm slowly getting it. Maybe.

 

[Cyrano]

In no particular order:
25 ACP
30 Mauser and 30 Luger
8X50R Austrian
8X56R Hungarian
7.5X55 French
8mm Lebel
6mm USN
8mm Nambu
8mm Mle 92 French revolver
11mm Gras
455 Webley
50-70
Maybe a few others I've forgotten.

 

[Homie]

Here are a few of my wildcats that haven't been mentioned yet:

.219 Donaldson Wasp
6x47
.243 Super Rockchucker
.25 Gibbs
.30 Gibbs

Good shooting.

 

[Andy Griffith]

I figure the oddest I load for:

7.5 Swedish/7.5 Swiss revolver cartridges
.41 Short Colt
.41 Long Colt
12/14 Gauge Greener (12 gauge necked down to 14) How many fellers load for it? Most people rechamber or rebarrel the guns.
All gauges of shotguns in brass hulls, with exception of 24 gauge- I don't have a gun for that.

Until it was stolen, I reloaded for my T/C Contender in .30 Herrett, a shortened .30-30 case that was more efficent in the shorter Contender barrels. Awesome rounds, very potent.

I hope the creep who stole it has luck finding ammo for it as it was never commercially produced--had to make each and every rounds.

 

[Grinder]

Only the .356TSW

 

[KSCowboy]

Well I kinda got the need for speed for varmints.

17 Hornet
17 Mach IV
17-222
22-284

Rounds out my wildcats. Shoot the 17-222 the most as it is my always in the pickup truck coyote gun. Just saws crows in half, I love watching the head half fall out the front of the tree and the back half fall out the back of the tree.

 

[deanodog]

45AR for 25-2

 

[fredj338]

I think fredj338 wins the prize!

In addition to the usual handgun cartridges, I reload:

.25 ACP
.32 S&W for a Lemonsqueezer bicycle gun
.38 S&W HBWC's for several Lemonsqueezers, a Victory, and an I-frame Terrier
.45 Auto Rim
.455 Webley for a WWI 2nd Model HE.

You gonna send me that Webley?????

 

[imashooter2]

The most esoteric caliber in my collection is the 7.62X51R.

 

[raisedin99]

416 Rigby for my Ruger 77 Safari

 

[Driftwood Johnson]

Howdy

45 Colt
45 Schofield

44 Russian
45-70

[yaktamer]

.43 Bubbenstein Improved

 

[ptk]

.41 Action Express: .41 magnum bullets, 9mm Luger shellholder, very hard to find or make brass, in my Jericho 941 semi-auto pistol. The pistol has parts (barrel, recoil spring, mags) to convert between 9mm Luger and .41 AE. I leave it as an exercise for the reader to speculate where the number "941" in the pistol model name comes from

 

[haggis]

7.65 French Longue (1935A, 1935S)

[HKSmith]

You gonna send me that Webley?????

Sorry Fred, but I think Alk8944 outdid you!

But just so you know what you're missing out on, my .455 has the officers name and regiment engraved on it and I have extensive documentation of his service record and medals - makes me feel very historical when I shoot it.

 

[colt_saa]

Ones that are not too odd
17 Remington
9x23 Winchester
45 AR
45 Win Mag
50 Action Express


A little more odd
10MM Magnum
300 Whisper
357 Maximum
357/44 Bain & Davis
357/45 Grizzly Winchester Magnum (waiting on dies)
475 Wildey Magnum

 

[Shuz]

In my IHMSA days, I used to load for the 7mmTCU in a TC, and for the 7mm Ugalde(same basic .223 case necked up) for an XP-100 Remington. I still have the capability to load for this cartridge and still have the TC in 7mmTCU, but I haven't shot it in over 10 years. My how time flies!

 

[TSQUARED]

The most unusual calibers I reloaded were 8x68S for a pre WWII German Mauser, 360x 2 1/4 in. NE in an old Alexander Henry single shot and 40-70 Peabody What Cheer for a Peabody-Martini single shot.
