[QUOTE="J E Custom, post: 847660, member: 2736"] +1 I have a chronograph and still have to shoot different distances to verify drop and BC of the bullet. The bullet makers BCs are seldom perfect (Always on the high side) Shoot your load @ 100, 200, 300, 400, 500, and 600 yards using the same aim point(I use a large piece of paper with the aim point at the very top and start shooting 3 shot groups at 100 yards. then I back up to 200 yards and repeat the process. Continuing one to 600 yards. You can then measure the drop at each distance and if you use this drop and compare it to your loading manual you can get close to the velocity of your load. Velocity may vary due to the actual BC of your bullet but it will be close. I use my chronograph more for load development than anything else. J E CUSTOM [/QUOTE]
