CORRECTION ! CORRECTION !

I just noticed Hodgdon's pressure is listed as C U P. Not PSI.

If you want to know the correlation between PSI & CUP, our EINSTEIN (SERIOUSLY,not mocking) Denton has the mathematical forumla. on 'shootingsoftware.com'. I googled psi vs cup and brought it up. He has 6 pages and IN THERE is a formula. He has a great treatise on this subject.

I found what I needed.

Thanks Denton
