ME is mass x MV x MV, so drops very rapidly in short barrels.
My first choice would be the short barrel ammo in a short barrel for controllability.

I knew that, that's the main reason why I posted this thread as I know that the barrel length will make these rounds perform differently. I was wondering if Speer chose the 180 as the short barrel weight due to more ballistic gain due to short barrels or what. For all I know, the short barrel ammo could be the same as the original 180 with the rough velocity from a shorter barreled handgun.
