[QUOTE="MontanaRifleman, post: 850137, member: 11717"] It is simple to do yourself. Here's how.... First you calculate the area of the throat which is, Pi x radius squared. The radius is half the cal or bore diameter. 3.14 x (.1285x.1285) = .0518 Then you get the case capacity, which I get from Ammoguide and divide the capacity by the throat area. 80.3/.0518 = 1550.2 [/QUOTE]
