[QUOTE="Jumpalot, post: 1906058, member: 4867"] I used to use a chronograph but quit about 5 yrs ago as I could never get them to match with what my ballistic apps proved out. I had an Ohler 35 and used a Magnetospeed. I can usually "guess" what my load should do and put that into the ballistic app. I'll shoot 500-600 yds and make adjustments then shoot 900-1100 yds and make more adjustments if needed to fine tune my drops. My last rifle took less then 10 rounds to get everything dialed to hit from 200 yds to 1200 yds. which is as far as I'll shoot a 7lb 6.5 PRC. Used the same process on my 338 Edge and have had 1st round hits a few times to 1780yds. I understand wanting to see data that shows ES and SD but I can see if a load is showing vertical dispersion without a chronograph. A pretty popular gunsmith that is on this site built a gun for me that was giving me fits. It was grouping well but the numbers looked bad. He told me I can chase numbers until my barrel is toast, or find a load that shoots well and then just go shoot. I've personally given up the chronograph game but enjoy reading what others experience and learn from it. I hope you figure it out. [/QUOTE]
