Can discarding sabots be used in revolvers?

I am curious about technical aspects of using .22 and .30 caliber bullets in a .357 revolver. Would a 40- or 55- grain .22 projectile stabilize properly? Would sabot clear the forcing cone OK? Any other concerns?
 
The only concern I can think of with a properly designed sabot is to use enough crimp to allow the powder to burn properly with such a light projectile. You might run into backed out primers for the same reason. Remington got around that with their Accelerators by heat sealing the plastic sabot into the case.

It is not often recognized, but when a cartridge is fired, the pressure in the primer itself tends to force it out of the case, then as the main charge burns, the pressure forces the case back over the primer. If there is not enough pressure to do that, the revolver can hang up.

Some years ago a company (unfortuneatly I can't remember the name) offered sabots which allowed usung .357 Maggnum bullets from .44 Magnum cases. It seened to work allright although the accuracy was mediocre. Occasionally there would be a very wide flier probably due to sabot didcarding problems.

Have tried sabots in Ruger Blackhawk. Put 38 158 gn swc in hornady 45 caliber sabot over light charge of HP-38. Bullets remained stabilized at 25 yds. The sabots were found at about 20 yds. Only tried 6 of them, didn't chrono them. The sabots used up a lot of the case volume, and they were acceptably accurate and extremely pleasant to shoot.
 
My only concern is their legal status. Here in FL, I don't think DS small-arms ammo is lawful to possess.

Don't give me a "smarter" gun.
Make me a smarter shooter :D
 
I see 30-30 Accelerator ammo and 50 BP sabots, as well as sabot slugs for sale here. I expect the only legal no-no is placing "AP" bullets into pistol rounds.
 
I am in the process of loading Hornady 35gn V-Max bullets in a 30Carbine B-Hawk. For your 357 project the biggest concern I would have would be getting the sabots. I can get the 30 cal sabots, I can get the BP sabots, I can even get the 50 cal SLAP sabots, but I have not seen any 357 sabots. I imagine the 40gn bullets would stabilze, the 55's might be kinda dicey. I heard that the Colt Python had a faster twist than standard 357's and so it might work better with the 55gn bullets. If you can throw them fast enough, 55gn bullets should work OK with about a 1:14-1:16 twist. IIRC the Python has 1:14. Semper Fi...Ken
 
I asked at the local reloading shop today and they said that if I can find ANY sabots other than 50cal to let them know. Where are you buying yours?
 
I was not happy with the flimsy polyethylene sabots available for BP and handgun use. The polyethylene ablated badly in the bore, and often separated or went nonconcentric prior to leaving the bore.
I had a local screw machine shop make some up out of MDS loaded Delrin (acetal).
The Delrin is much harder than the polyethylene, and the moly gives it great surface lubricity.
They did the body, and I cut them for separation with a single edged razor blade in a small arbor press.

I was able to achieve ungodly velocities out of standard .45 acp chambered weapons lofting 125 grain HP .357 bullets. The first batch were coming out of the barrel at very high speeds, up to 1800 fps.
I loaded some faster ones, but the first sabot out of the barrel with them sepatated and hit the chronograph, destroying it.
Doh! Good thing it was a borrowed chronograph...
Accuracy was combat adequate, but not bullseye match quality.
