[QUOTE="dok7mm, post: 1554697, member: 90080"] If you just shot one round of each charge, they won't tell you much, compared to the average velocity of 3 shots. Several things could influence your Chrono numbers on one shot....... like barrel condition or temp and the fact that one fireforming will not usually expand your brass fully to chamber dimensions. I would suggest firing 2-3 foulers and then shoot groups of at least three rounds for average velocity with the same wait between shots. I don't bump shoulders until after 2 firings, unless the brass won't chamber. This way, I just have to set up my die adjustment one time. [/QUOTE]
