Quickload info, Please!?

Can someone tell me the pressure at the muzzle for a supersonic load out of a 10" barrel? Let's say a 125 NBT pushed by 17 grains of VV-N110. Just wondering how it compares to something like a 16" .223, or a 20" .308. I would really appreciate it!

According to quick load the muzzle pressure would be 7863PSI, chamber pressure would be 45895PSI and a velocity of 1937FPS

Those numbers look like they're for a load loaded to mag length.

Everything depends on your COAL. Loaded to 2.150", which is what I have to load to in my short-throated M1S chamber, chamber pressure is a little over 56K, muzzle pressure 7573, muzzle velocity 2021, out of a 10" barrel.
