Title: Need help with sweet spot for BOSS
Post by: Lungbuster on July 15, 2009, 07:50:45 PM: I have a browning A boltII in 300wsm and was curious where to start for the "sweet spot" I will be shooting Fusion in 180 grain. I have looked on their website but it does not list the ammo

We started at the middle of the micrometer adjustments and played a little both directions to see what the results where. I am sure it will be differn't with each rifle and caliber. It definatley tighted the group up thou. It takes time because we would take a shot with the barrel cold then wait until it cooled back down again. We cheated a bit with 2 shot groups for awhile. Have lots of ammo and targets. Lots of time helps too. :)
