Some good points, this is a start. Ultimately the future will have the manufacturers giving more than just bc/sd/weight/velocity. They could provide a few other numbers with that and then when you spit your charts out there's a few more columns on the back end showing what to expect on the terminal side of the equation like penetration depth, expansion ratio, energy release ratio and it could mirror all your distances chosen to show the efficiency window etc. FBI has their system to help them choose ammo terminally...hunters don't have this. We have the in-flight data and SD and we get to subjective it from there...not good enough for the 21st century imo. Manufacturers who get on this will be able to drive sales and innovation more on terminal performance than just in-flight performance. It's the future as it's a gap right now.
Be nice to show why the 6.5 Creedmoor essentially rolls the .308 to the 30-06 capabilities up into one cartridge/bullet combo. Or why the .223 with 77gr tmk's is such an apparent overachiever. Need to be able to compare. The answers should lie in the finished bullet, AS WELL AS the 'internal trajectory' from impact to the finished bullet. We will figure this out.
If in the night some ideas come to you, dig up the thread and add to it. I've got the concept and some possible new measures in mind with SDRR and ERR, and the other night I even wondered if spin is a measurable to explain the bombs that go off inside critters or not? Ie; x-amount of rpms over x-amount of inches travel? Still sort of preliminary really. Not sure why we wouldn't measure every thing possible and then figure out the formulas that show best what to expect compared to any other bullets etc. Which measures are the most effective and to be standardized and built into calculators etc.?
