[QUOTE="MontanaMarine, post: 1021364, member: 268"] Today I put some rounds over the chrono, into a 100-yard target. I fired two rounds of each load increment. Not enough to qualify accuracy, but I wanted to have a second round in case of a chrono error. I put the rounds on paper and will include the 'group' size. The purpose of this session was primarily to check velocity, and look for signs of excess pressure. I will do further accuracy/BC analysis on a selected load. I normally shoot from the ground with a bipod. To accomodate a chronograph, I set up on a table, with a BR front rest, and sand filled rear bag. I set the chronograph out 5 yards/15 feet. Target was at 100 yards, lasered. Rifle is a Rem 700, 22.5" Douglas #7, 1/10 stainless bbl, McMillan A2, SWFA 12X, Badger Ordnance mounts/brake, knob, lug, floorplate.
