[QUOTE="bigngreen, post: 1036446, member: 13632"] I use the calibration tool a lot to fine tune, it's key to NAIL all your other inputs, my 308 is a great example of the tool working, I put targets up at 100, 300, 1030 and 1535 yards then shot them based on the data from when I zero'ed. My 300 and 1030 were a little of, a minor tune to the zero high put the 300 dead on, then I ran the calibration tool for 1030 which lowered my MV by 4 fps from what I got from the magneto. The 1535 was also of a little so I ran the correction in the second range which changed it just a touch, I'm saving the range 3 for dialing in once I pass transonic. This took little time and some ammo and careful inputs and it has yielded first round hits at 1535 yards on a target rock that is just under 1 moa, with a 308 Win! We did a very similar procedure dialing in Broz Terminator but using the custom drag and in such a chambering we took it beyond 2000 yards running about 1/2 MOA with NO calibration, but you can see that at some point a little tune may be good but it's at such a range that getting a day with the right conditions to put it on paper to 3000 yards with confidence of what your seeing just is not happening.
