[QUOTE="toddc, post: 740239, member: 4566"] I use one to check theories and check ES but thats it. I also dont ever believe a chrono over a drop or spread. Only real issue which isnt really an issue is that you will never KNOW a real velocity. Of course since 2 chronos never agree and I cant get a cop and a radar gun to stand in front of me the point is moot. There can be a huge downrange data diff. due to the barrel. HUGE. Ive had 4 edge barrels. All shot within 5 fps of 2850. 1.25 moa elevation difference from worst to best at 1k. 1 needs more spindrift and windage than the other 3 and 1 needs less with 2 in the middle. May seem weird but it is what it is. And this is logbook data not my faulty memory. [/QUOTE]
