[QUOTE="jarnold37, post: 1821378, member: 29241"] I too am missing something because my little brain is trying to understand this from a practical standpoint and not mathematical. I know, I just showed my lack of perspective. However, if the cartridge case has x lbs of rearward thrust, it seems that amount of thrust will be equal given that the bigger case head dissipates the thrust over a larger entire case head meaning that the result is the same rearward thrust only spread over a larger surface. The sum of that dissipated thrust is the same as a smaller case head with same thrust only concentrated in a smaller diameter. A 20 ton press punch, 3/4" diameter exerts the same energy as a 1" diameter punch only concentrated in a smaller area. [/QUOTE]
