[QUOTE="Teri Anne, post: 2303849, member: 118816"] Well there ya go. Variables happen and for the most part are out of our control. Temps, barometric pressure, elevations above MSL, Air density (and this is important) as well as the possibility of either powder scale or chronograph errors are all things that enter into the equation . As an example, I took my favorite rifle out with my favorite hand load to the range on a bright sun shiny day with the temps in the high 80's. Chrono says X number of FPS. Next time temps in the 60's, chrono says so much less. Want to take those temps even further down into zero temps and you now have even more variation. Each and every shot is different. None will be exactly the same as the one before it. Changes in load data, temps, altitude, barometric pressure and the list goes on all have an effect on each round fired. There is no correlation between round 1 and round 20. Each will be a tiny bit different but if you are careful, remarkably somewhat the same, but different. [/QUOTE]
