I think the sabot would be the diameter of the barrel, and so would spin, and would transfer the spin to the projectile.
4000 fps?
2253

I saw some 30-30 ammo on Ammo to Go. It had a sabot with what I think was a .223 round inside the sabot. It said that it had a velocity of over 4000 fps.
Why would someone want a velocity that high?
What are the downsides? For instance, it seems that since the .223 round is nowhere near the diameter of the barrel, the rifleing would not do any good, so the round would not spin and accuracy would be lost.
So why do people want a 30-30 cartridge, that shoots a .223 round, that has a velocity of 4000fps, that might also not be that accurate?

Never heard of it and I doubt a 4000 fps 30-30 round exists.
No polymer sabot could take the pressure.
The .220 swift is the only .22 cal bullet I know of that approaches 4000.
The C.U.P. pressure whould have to be around 53,000:xeye:

Oops. It is 30-06. The 30-30 is 3600fps.
See here, or the link below.

That makes sense that the sabot would transfer the spin.
I don't think the pressure would be any higher. It is just that the same pressure is applied to an object of less mass. F=ma. F is the same. Mass is decreased. Therefore acceleration, and consequently velocity, is increased.

Maybe they make them so you can shoot small game with a big gun and not ruin too much meat?

Faster means flatter trajectory. Less drop for increased range.

Yep, but one downside is it doesn't do very well in cross winds. It's ok for a varmit buster in the field and as a defensive round inside a house for it shatters in flesh real easy. It's one of three rounds in .30-30 Winchester thats able do that.

They are called accelerator rounds produced by Remington. Designed to turn a big game rifle cartridge into a varmit hunting cartridge.
The idea was to extent the usefulness of standard .30 cal. ammunition by using a plastic saboted .22 cal bullet. Accuracy will vary between rifles some like the sabots some don't.

DOn't get hung up on the cool sounding stuff. You pay for the cool too much.
