Discarding sabots - ever used on small arms? Login/Join

308 Winchester “Accelerator” on left; handloaded 0.358 caliber bullet in 44 Magnum case on right. The handloaded discarding sabot rounds never performed well for me. The sabots sometimes did not separate from the bullets and recovered sabots were usually severely deformed, indicating that they disrupted the flight of the bullet when it left the barrel. The seller of the sabots claimed good success with his loads, so I don’t know why mine were a failure. There are of course always many variables with a project like that and it’s possible things would have worked better for me if I had found the right ones.

Thanks for the info, all. Smile

Looks like an idea that has been tried, but with practical issues in execution; the devil is in the details.

Very interesting.

To echo what Sigfreund said, that's more or less the experience from the InRangeTV video I referenced (sample size of only 2 rounds, though). The one round keyhole, likely because the sabot broke up.

Seems that sabots work well for tanks, but not so well for small arms.

My understanding is that ceramic plates work by being harder than the bullet, so the bullet shatters on impact, but the also-common polymer plates work by "catching" the bullets and performance is velocity-dependent.

I suspect a 55 grain bullet going 4000+ fps out of a 30-06 would zip right through a polymer plate.

Of course, there are plenty of other ways to get a bullet going really fast.


And you would be incorrect. Steel plates were prone to failure at higher velocities. Higher velocity rounds were a reason that ceramic plates were invented. That and weight. Even if you took a hit from one of these rounds up close, it is highly doubtful that a quality ceramic plate would give. Adding any distance and you loose a ton of stability on these types of rounds.

Read again - I was saying that I didn't think it would matter as much for ceramic plates, but that it might with polymer plates.

There are a lot of polymer plates with ceramic strike faces, but there are also plates that are just a solid block of UHMWPE.

My reading is just fine. It is your post that is incorrect.

Can you provide a reference for UHMWPE plates reliably stopping MUCH faster projectiles than the NIJ standards test for?

Velocity certainly seems to matter since military body armor standards test for "V50," the velocity at which 50% of the projectiles penetrate the armor.

If nothing else, any piece of armor is limited by the amount of energy it can absorb, and higher velocity means more energy.
