Thanks for the info.
nksmfamjp I have to respectfully disagree with your statement that bullet diameter is the only factor that results in a kill.
I found this site on testing of the new .327 SP-101 and found it interesting that the little round has alot of velocity.

Article states:
Federal is offering three factory loads for the .327 Federal Magnum at this time; a Federal Premium 85 grain Hydra-Shok hollowpoint at 1330 fps, a Speer Gold Dot 115 grain hollowpoint at 1300 fps, and an American Eagle 100 grain jacketed soft point at 1400 fps. These velocities are advertised as being fired from the 3 1/16 inch barrel of the SP101. I only had the American Eagle load for testing. It chronographed at an average velocity of 1374.9 fps at eight feet from the muzzle, so corrected to muzzle velocity, the Federal specifications are dead on accurate.
I also liked the real world testing of using Meat (pork shoulder) to check the penetration of the round.
Article states:
Next I moved on to testing the .327 Federal Magnum for penetration. As mentioned early on, I am a believer in penetration above all else when it comes to a cartridge that will be used against flesh. The .327 Federal Magnum is marketed as a defensive revolver, so it had to be tested in flesh. Since shooting live humans is illegal, immoral, and distasteful, and fresh cadavers are hard to come by out in the woods, I rode into town and bought a whole pork shoulder from the local butcher. I told him that I wanted the biggest one that he had. It weighed just over twenty-three pounds. Again, I used only the Federal factory American Eagle 100 grain load for this test. I had three reasons for this: I wanted to use a load that is available to anyone who buys one of these revolvers, most people will carry their defensive handgun loaded with factory ammunition, and meat is expensive. Taking aim from a distance of ten feet and aiming just inside the shoulder blade, I fired into the pork shoulder from the end. The American Eagle jacketed softpoint bullet fully penetrated the shoulder. I had hoped to be able to stop the bullet and see just far it would penetrate the meat, but sixteen inches was the entire length of the shoulder. The entrance and exit holes were very similar, with some cratering around the entrance. Opening up the shoulder, about seven inches in showed a large amount of cavitation and tissue damage. Seven inches is about optimum for this. Measure into your chest about seven inches and you will see that there is a lot of important stuff in that area. This damage started near the entrance, peaked at about seven inches, and then tapered into a channel of about one-half inch diameter through to the exit. I am very pleased at the performance of the penetration test.
So all in all I think the new ammo is perfect for a lightweight CC that can get the job done.
I don't look forward to the taking of a life and if the little round will disable the perp and allow me to escape unharmed that's all the better. Besides, if the situation requires me to finish the job then there are 5 more rounds in which to do so.
