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?
