[QUOTE="pwrdbycotn, post: 1136176, member: 29096"] Hmm, well a couple thoughts and questions come to mind. 1. Why does the chrono have to be 100% correct? Isn't the only thing that is required to be correct is the known bullet path? Since this is a hunting website I feel as though this is the only thing that truly matters since we are shooting at live animals and not just paper. 2. Can't the chronograph numbers be adjusted easily based on that known bullet path? If the numbers can be easily adjusted, then isn't a chronograph just a tool that is used to give a good starting point for making scope adjustments at various ranges? 3. Is there a chronograph made that is guaranteed to be 100% correct, 100% of the time? If so, is it remotely affordable and where can it be found? 4. Asking me about how other people verify their chronograph is correct doesn't really belong in this thread. I started this thread asking about adjusting muzzle velocity changes in ballistics calculators to match verified bullet paths vs possibly changing B.C's to achieve the correct drop. I was also surprised that the numbers had to be changed so much to get it correct. It took me all of 10 seconds to change those numbers so I'm certainly not laying awake at night fretting over whether my chronograph is correct or whether the software used is giving me the correct drops. I have better things to do and more important things on my mind than to worry over useless drivel like that when it takes all of 10 seconds to make it right. 5. Apparently the adjustments made to the muzzle velocity were the correct thing to do because tonight my G7BR2 called for 6.6 minutes up and I dropped a whitetail in his tracks at 506 yards.
