Hello all!

I have a truly meaningless question to ask but I just wanted to learn a little more about penetration qualities of same caliber bullets. Say one wanted to calculate the penetration of a 9mm FMJ load in say ballistic gel, I will offer two common practice 9mm TMJ RN loads from Speer say the Lawman line and we will use the 115gr TMJ RN http://www.speer-ammo.com/ballistics...x?loadNo=53615 at 1200fps and the 124gr TMJ RN http://www.speer-ammo.com/ballistics...x?loadNo=53616 at 1090fps. Now I know everyone will say to buy, mix , fire and measure and you will have the answer but I was wondering is there some type of calculation were one can add all the info on the bullet and the media to be shot and come out with some kind of estimate?

Thanks!
