Default Sabot for 357 Pistol

Hello learned friends,

I own a Westlake 357 Pistol which is of UK manufacture.
The pistol is, under UK Law a muzzle loader.
The cylinder is loaded just like any Black Powder revolver but it is proofed for Nitro therefore classed as a Section 1 Firearm.

As I now want to experiment with some different ammo, I would like to know where to buy 357 Sabot's that would carry smaller bullets like .30 or .25 size.

If anyone could point me in the right direction it would be most appreciated.

Good luck finding what you seek. The smallest sabot that I know of is the .36 caliber Grey sabot from MMP.
They will hold bullets .311-314"......essentially .32 caliber bullets of 71 to 100 grains. Problem: ".36 caliber" muzzleloaders are really .375"..too big for your gun.
Also...there are a number of other significant issues associated with what you want to do. Here is a post detailing some things to pay attention to if you do find what you need:
To shoot what caliber? .32? .30? .22?
Sabots are used to shoot a subcaliber projectile. I haven't heard anything about this for the .36 caliber revolver.
It may be offered for the .36 caliber rifle, which would make more sense. In a revolver? I see problems.
Historically, sabots have been made of wood or some kind of plastic. Either would lack the "stickiness" of lead to remain tightly in the chamber as the other chambers created recoil.

The idea of sabots is not new, dating at least to the 1870s. I seem to recall experiments with the .45-70 service rifle using a wooden sabot loaded with a lead .30-caliber bullet -- something like that.

Anyway, cap and ball revolvers have pecular challenges that cartridges lack.

For one thing, you cannot crimp the projectile into the revolver's chamber, but you can crimp the brass case into the bullet, to prevent shift during recoil.

Also, the seated lead bullet seals off the chamber, preventing flame from reaching powder charges behind each seated projectile. I don't see wood or plastic being nearly as effective as lead.
Perhaps the manufacturer suggests filling grease grooves in the sabot with lubricant, to prevent this. So now, yet another step in the process of loading a cap and ball revolver.
There are already plenty of impatient shooters who want to eliminate steps, not create more, in the loading of their cap and ball revolver.

Most cap and ball revolvers have rudimentary, non-adjustable sights.
Using a sabot means using a projectile that weighs significantly less than normal. Consequently, such a light bullet would strike far below the point of aim. Lacking adjustable sights, this would create a sighting problem.
Considering that cap and ball revolvers typically place their shots high, though, this may not be the problem it appears.

I haven't heard of any sabots being produced for cap and ball revolvers. I wonder if someone unfamiliar with combustible cartridges hasn't seen those, and thought they were sabots for cap and ball revolvers?

But getting back to your original topic: Nope. Not heard of this. And I don't see a need for it, either.
