Why would you want to know???
I am an educator and I teach chemistry and physics...so by default,
data tables,
charts and
graphs fascinate me. When I start working with a firearm, the first thing I do is consult the data tables for that calibre and develop a load plan for that firearm based on the published load data.
As I look through my load tables for my .32 calibre that I made years ago; I see that an 18 grain load of 3fg, behind a .311 round ball is ballistically very close to the published data for a .22 LR. My standard hunting load of 32 grains of 3fg behind that same round ball is a little hotter than the stated data for a .22 Magnum.
I have a few loads for the .32 Calibre Maxi Ball...But I never used the my chrony to collect data on those loads. Published data would give me a ball-park of where my loads are sitting as far as velocities and energy.
I've shot my .32 for many years. And I've developed a set of loads for the rifle,
but how do my collected data sets compare to the published data for the .32 calibre?
