Good evening!
A while back, though not too long, I started a thread about pistol vs carbine. I also promised to include data when I worked it up. You can find the original thread here: http://www.thehighroad.org/showthread.php?t=810127

Anyhow, I actually got somewhat higher velocities out of the carbine than I expected, but judge for yourself; will attach the final two files with another post. The "Acme red RN" are 115 grain HiTek coated,bullets made by Acme Bullet company; they are about 20 miles from where I live, and I can't say enough about their customer service; I had an issue with some of their 124 grain RN- not their fault, I was loading them a hair too long for the carbine and the owner invited me up to the shop, gave me a tour, and between us we worked out what was wrong with my loads.He even gave me a number of samples to try; for instance, a FP 122 to try instead of the 124 in the carbine, a RN 145 to try alongside the 147 FP I have used with great success, and some more of the 115 and some 185 SWC .45 to try instead of the 200 SWC I had been using. Do yourself a favor and check http://www.acmebullet.com/index.php?route=common/home
to compare prices; some of the best around that I've found.
I'll submit this, then another to attach the other two files. the things to look at:
ASR is the Aero Survival Rifle, 16.25 inch barrel; XD is a Springfield XD, 4" barrel, I used Blue Dot and W231, and the Acme 115 RN and the Extreme plated 115 RN. All were loaded with Sellier & Bellot SP primers

Excuse me? what exactly do you mean? You have a formula?, or you'd like me to work on one?, and, if so, I'm racking my brain trying to figure out what powder ME is, because I'm pretty sure I don't have it.
 
If you mean "Muzzle Energy,
This works better for me, my dad came up with it...
take the velocity(fps) and divide it by 1000.
now square it
multiply that # by 2.22
multiply that by the bullet weight in grains
This is the muzzle energy on Earth.
