[QUOTE="Deleted member 46119, post: 1301358"] I think what THEIS is getting at is: What is the maximum body diameter of the brass casing an RPA action can take, example. BMG is .804 14.5 Russian is 1.057 60 MAchine Gun is 1.142 20mm Vulcan should be 1.142 as the 60 Machine gun is necked down 20mm Vulcan If that is the question the answer depends on the barrel tenon size. I only know a couple big actions and they are not BMG sized, they are 1.2x16 threads. 1.2 - .804 = .396/2 = .198 wall thickness, Not enough. 1.2 - .740 = .46/2 = .23 wall thickness, OK. So to base a round on say a 14.5 Russian 1.057 + .3 wall thicness * 2 = 1.657 minimum barrel tenon diameter. Lets round that up to 1.6875 - 16 with a 1.25 length. Am I going in the right direction?
