Metal God,

The 175 SMK handles the transonic zone quite well, what really will 2700 fps give you that 2650 won't?

Alliant shows a max charge of 47.7 grains of PowerPro 2000-MR gives a velocity of 2,720 from a 24 inch barrel. There are those who are convinced you won't get long range accuracy from a ball powder though.

Machine guns are awesome until you have to carry one.
