I was wondering if anyone may have suggestions to help with the cause of this pattern. It was shot with a Browning BLR Iin 6.5 Creedmoor. 147 ELDM with H 4350. The first 3 shots were one after the other. With the 1st being in the center 2nd in the upper and 3rd in the lower. Shooting began with the barrel warm to the touch from the summer heat and additional shots from before. After the first 3 shots a break was taken to allow cooling . During the 4th-6th shots additional cooling took place that was random while I delt with kids and dogs removing a warming trend. But the last 3 bullets followed the fist 3 in order making 3 different groups into a 1.1 inch group at 100 yards. Although the first 3 shots were fired in a rapid succession, the last 3 had cooling in between shots. The 6th shot had a good 5 min or more of a cool down. Curious if any would have some insight. Thank you.
