Here are the velocities I recorded when I did a shoot off with my friend and how DD5. All of these were the average of 10 shots through my PACT chronograph.
I use a handload with a 178 Hornady ELD-X through my MR762A1, and I regularly shoot it out to 1,100 yards. The average velocity for it is 2500 FPS. A few weeks ago a friend and I had a wild hair up our behinds and we shot out to 1,609 yards. I hit 3/12 and it took 91 MOA up to get there (dialed 71 held 20).
