There are lots of numbers out there if you are inclined to do the finite element analysis and math modeling.

Or you can do as I used to do – keep adding Varget until the primers and cases exit the chamber separately – then back off one grain.

Just kidding.

It drives me nuts to see reloading data that uses both units. Come on powder companies, stick with a unit that can be converted to another. I don’t care if you use MPa, at least that can be converted to psi,

If you do a search on line one can come up with a formula that provides an “APROXIMATE” correlation between the two units. I have found that useful for comparative purposes but not for precise measurement. I suggest anybody interested read the associated explanation very carefully.
