PDWs...and other small arms.

That carbine bullet seems to have tumbled!

Yes, but not very quickly....I think that the contrast with the JSP makes my point very well.

Next question: "How much room do we have for lengthening either the 7.62X25, 7X25, or 6.5X25 to at least the same as the 110 gr M-1 Carbine FMJ bullet?"

That means that either the overall cartridge length will increase significantly, or the bullet will extend a lot further into the case, further reducing performance.
