[QUOTE="J E Custom, post: 434707, member: 2736"] Lucas. most chronographs sum up all of the velocities and give you- Max velocity, Minimum velocity, Extreme Spread, Standard deviation and average velocity. If yours doesn't then yes you add all of the velocities and divide by the number of shots and you will get the average velocity and other numbers if you look at highs and lows. But the velocities you get will be slightly slower than the actual muzzle velocities because of the loss of velocity between the barrel and the chrony. This loss is not important at short ranges for drop charts but at long distances it can mean the difference in a hit or a miss. Varminator. The Oehler 35p has Three screens and it gives you the velocity of two separate sets of screens that compare velocities (A proof screen against the other set of screens) to verify the velocities and if the two velocities are to far apart it gives you an error message so you can delete that round and not skew/contaminate the other shots with a bad number. And yes it uses the first two screens for the proof channel and the first and last screen for the actual velocity that is why the first set of numbers on the print out are always a little slower than the actual velocities because of the screen spacing on the proof is 2' and the actual velocity screens are 4 feet (If set at 4 feet spacing). This is one of the reasons I really like the Oehler 35p. It checks it's self for accuracy. That's why I set my chrony at 4 feet intervals . my screens are set at 4 feet and I can get the velocity drop from 2 feet to 4 feet and add that to the estamated velocity drop from the muzzle for an "estamated" muzzle velocity.
