[QUOTE="orkan, post: 2482760, member: 25377"] The vertical you're seeing is likely aerodynamic jump... and it can be accounted for. If the wind switches from right to left, to left to right, by any margin at all, it will pull a vertical change. Once I understood that, making first round hits at distances beyond 1000yds became much easier with everything, but significantly so with smaller cals. When I compare the capabilities of my 338LM based cases to that of my 7mm Norma Mag Improved shooting 195EOL's at 3100+... not just on a calculator, but in the real world, I don't miss taking my .30cal or 338's out at all. I would feel MUCH more confident in my 7mm than 30 or 338cal in a 1000yd shot. Most bullets in 6.5 just don't seem to handle conditions well compared to good bullets in other cals. Case in point, yesterday I had a customer here and we were forced to zero his rifle in some pretty rough conditions. 20mph 9:00-10:00 winds. At 100yds, I had to build in .2 mils of vertical and .3 mils of wind to counter the aerodynamic jump and crosswind. Once that was done, walking MOA targets out to 700 was no problem. This morning the wind is dead at 3mph... so we are going to confirm. I expect it to be very centered up. ----------- [URL='https://www.instagram.com/primalrights']Follow on Instagram[/URL] [URL='https://www.youtube.com/user/primalrights']Subscribe on YouTube[/URL] [URL='https://amzn.to/3txlBnp']Amazon Affiliate[/URL] [URL='http://www.primalrights.com'][IMG]http://primalrights.com/images/signatures/sig1.jpg[/IMG][/URL] [/QUOTE]
