What is this?

Bought this off eBay on a last minute auction from the UK, round is inert, no powder and primer is spent. Casing says "IMI 308 WIN". Looks like a 5.56 round in a 7.62 casing or .223 in .308. Can anyone figure this one out? Seller couldn't provide anymore info on it.

Accelerator . 5.56 in a sabot . Pathetic accuracy in any gun i've used them in .
 
its a sabot .308 round probably used in a gun with a lower calliber. dont know if they are legal ???? anyone know?
 
They're legal, but Remington stopped producing the Accelerators because they never sold well enough to make them profitable, and they were never accurate enough to be used for what they were sold as (small-game or varmint rounds).

It was shipped from the UK as inert and opened/cleared by Customs Canada so I'm guessing that these are legal but what do they know? lol
 
IMI = Israel Military Industries, so its not a Remington. Same basic idea though. FMJ bullet? I don't know if IMI marketed such a load, or if it is made up. Perhaps SDC would be able to say.
 
I'm sure that this particular round was produced by a reloader, but the same idea has been tried a number of times around the world. In my cartridge collection, I've got a couple of examples of the US trial SLAP ammo that was tried along these lines, but it never worked out in the 7.62 chambering. The 50s worked very well, and are now an issue item, but the 7.62 sabots kept fragmenting in the bore, and they had several instances of the tungsten penetrator trying to go through the side of the barrel. I've sectioned one each of the 7.62 SLAP and SLAP-Tracer, and I'll post a picture of them later.
 
Accuracy with these was dependant on matching the correct twist rate of the 30 cal. bore to the 224 bullet. Same as any 224 bullet. If you are shooting a 12 twist barrel in your 308 you are restricted to 224 bullets no heavier than 55gr.
They won't shoot as well as when fired out of a 224 centerfire barrel but are capable of one inch groups at 100yds. if reloaded with care. The big issue after selecting the right bullet weight to match the 30 bore twist rate is bullet concentricity. If the 224 cal bullets are not centered properly in the sabot they will leave the muzzel like a badly thrown football and not shoot well. However if the extra care is taken to check bullet runnout and the bullets are properly alligned in the sabots they will shoot reasonably satisfactorily.
A handloader can take this extra care but a factory round that has been bumped around for monthes probably before it finds its way to your rifle is not apt to have the 224 bullet properly centered and hense the poor accuracy reports.
In Canada you can get these sabots for reloading from Blue Mountain Sports in N.B. 1-506-468-2919
 
Here's a shot of a couple of the SLAP rounds in my collection; left is a 7.62 SLAP with a tungsten penetrator, right is a 7.62 SLAP-Tracer. Despite the aluminium base-disk in the sabot of the SLAP round, the sabot still wouldn't hold together reliably.

Killed my first Coyote with one. Big SOB too.
Killed my first Chrony with one. SOB

The color of the sabot in the pic looks like a Remington original. All the one's I've reloaded were grey in color. Someone likely pulled it out of a Remington Accelerator and stuck it in another case.
