Gunsmithing Bartlein AMU contour?

AMU/MTU contour. A lot of times people are talking the same thing. The MTU stands for Marksmanship Training Unit. That's our #7 contour.

The AMU has been buying that contour and a slightly smaller contour that is basically our #14 contour but with only a 2" breech length and .900 @ 24".

They also buy different variations of the MTU and Palma contours as well.

Again though I think your thinking of the MTU contour that is our #7.
