9mm ammo ballistics

Question
I would like to know the velocity and or energy of a 9mm 147 grain winchester sxt load from a 3.5 inch barrel or 4 inch barrel if 3.5 is not available please.

Answer
Donald,

The following are approximates. There are many variables that can/do effect any supposed "exact numbers".

Taking only your listed perimeters into consideration:

The 147grn. has a muzzle velocity of about 900fps. and a muzzle energy of about 320.

At 50 yards it has a velocity of about 940fps. and an energy of about 290.

Thanks for the question Donald I hope this helps.
