Llama Bob - With all due respect what you are saying is not grounded in physics at all. First the 348 Win holds 75 gr/H2O, while the 444 Marlin holds 69 gr/H20, by all accounts that 6 gr/H20, not 10 gr/H20.
Had you bothered to actually read what I wrote rather than running straight to this blather, you wouldn't have missed a key part: "with the bullet seated". Only case capacity not occupied by the bullet is useful.
It's still physics, you're still wrong, and that's really all there is to it. It's OK if you want to be wrong of course - that's your problem. TKO is a made up number that has nothing to do with the power of a cartridge.
