[QUOTE="J E Custom, post: 2000243, member: 2736"] Anyone that reloads and likes extreme accuracy (Little Bug Holes) needs a chronograph !! The reason a chronograph is needed, Is the chronograph is unbiased and doesn't know when you are having a bad day. Everyone has there own way of using a chronograph while load testing, and here is mine. First I select the bullet style and weight I would like to use based on the barrel twist. Second, I look at load data that has powder charges that are near maximum pressure and near 100 % case density. Then I load in the middle of the powder charges listed using the same primer listed. Now I am ready the test using the chronograph. I don't worry about the accuracy at this point because I am looking for a stable/consistent load velocity. The lower the SD's the the better more the components are compatible with each other. Once I find a low SD load (Consistent combination) I can then change one component or measurement (like bullet seating,) at a time. I like and use the magneto speed because I start looking for the best Load first and then If I think it may effect the accuracy I will take it off. Most of my rifles have heavier contours and the Magneto speed has little if any effect on the barrel and the accuracy because of it's weight (Ounces). This process of looking for one thing at a time has reduced the number of rounds needed to arrive at an accurate load to less than half, and normally Will take less than 25 test loads. I also have a Oehler 35P to chronograph while checking or zeroing point of aim and giving velocities at the same time if needed. By using a chronograph for load development, It is not a hit and miss operation and It tells you the effect of any change you make, with out the human factor. J E CUSTOM [/QUOTE]
