Making a jig to hold 50 bmg brass and wanted to drill a hole to match the shoulder taper.  Anyone know the angle of the shoulder in relation to the centerline of the cartridge?  Since the cartridge is tapered I cant just take a measurement from the outside.  Did some google searches and wasnt able to find what i was looking for.  Hoping someone in here just happens to know.  See picture:      Thanks!

No pictures are showing but according to the Hornady reloading manual the angle of the shoulder is 15*44'.
