muzzle pressure calc?

[cohunt]

anyone have a way to calculate the muzzle pressure of different length barrels? is there a software like quickload that does this? or do they only calc. the chamber pressures?

Google it because I found a write up on it when playing with aluminum muzzle brakes. It's around 1k psi for a 300wm @ 26" according to this guys experiment

I found a good chart for the 223/5.56 as they have done quite a bit of pressure testing at gas ports and muzzles but for the 300wsm there isnt much data available that i can see
