Seems to me that the explosive in all 209 primers seem to contain the same stuff in the same proportions if their MSDS sheets are correct: lead styphnate, barium nitrate and antimony sulfide plus copper, zinc and iron.
It also seems that there is a direct correlation between how "hot" a primer is and the diameter of its flash hole; the "hottest" primers seem to have the largest flash holes and the "coolest" have the smallest.
And, by the way, the primer is just one component in the list of factors that determine peak chamber pressure. Too many variables to give a simple answer.
There is no way to tell. Use the data as written and keep your fingers crossed. Different primers will act differently in different loads. It's a crap shoot! If you have data, use it. If the data does not include your primers, get the right ones or find data that does. Ask the powder companies or send out some loads for velocity AND pressure testing. There are different compound mixtures and primer configuration that may determine how they work in a specific application. One primer may give high pressures in a load in a tapered hull and develop low pressures in a larger capacity straight walled hull. You have no way of knowing unless you have reliable data to support it.
