.50 Caliber Special Contours

50sp47The chart below has a listing of special .50 caliber programs that we have made in the past. Although listed as .50 caliber contours intended for the .50 BMG cartridge these can also be used for smaller calibers using the bigger diameter steel blanks such as the .338, .375 .408 and .416 calibers.

A CAD drawing of these profiles can be viewed as a .pdf file by clicking on the orange designation in the left column. We are also adding the weight (in pounds and with a .510″ groove diameter) for the profiled blank along with the CAD drawings.
