[QUOTE="Okanogan, post: 2556063, member: 90397"] I had a similar experience when breaking in my 6.5 SAUM. I chrono graphed all my shooting for the first 200+/- rounds. As the barrel broke in, the velocities and pressure signs increased. Everything seemed to stabilize after about 150 rounds. I backed my charge weights down to the velocities that had originally worked well and achieved the same groups I had early in my load development. It's hard to do load development while your barrel or your brass are changing. It is also worth noting that as you continue to shoot it is possible that the throat can wear and change the distance to the lands. [/QUOTE]
