[QUOTE="Alaska2006, post: 1350740, member: 92741"] Okay folks I have a question for those schooled in the use of the Kestrel 4500 with AB solver. I have verified my MV a few dozen times and verified drop at 300 yrd, 600 yrd, 1,000 yrd and yesterday verified at 1,766 just a shade over 1 mile. Problem I have is my drop at 600 yrds (much easier to deal with environment) gives me a verified drop of 9.68 MOA this is with Berger 215 hybrids/ 300WM with MV of 2,930 fps. elevation of 5,350 above SL, ambient temp. of 59 degrees, Baro PSI 25.56. My verified drop at 1,000 is 22.72 MOA. for 600 and 1,000 the kestrel solver is very close with actual drop less than 1.00 MOA . Problem is when I stretch out to 1,766 my Kestrel claims dial up to be 56.48 but my actual required dial up is 58.51. How do I get a bit more accurate shot solution at long range, or is this within reasonable expectations? I do have a couple other issues to resolve for my LR shooting. My reloads work very well but at these distances 20-30 fps change in MV is very noticeable. I have a great load worked up but need to work on narrowing my ES. Even with that some of the loads running a bit faster 2,945 ish still had greater drop than my shot solution was offering. All MV is verified using lab radar. Any help will be greatly appreciated.
