[QUOTE="Danny1788, post: 1364817, member: 19965"] [ATTACH=full]84363[/ATTACH] This is overly exaggerated but the top picture shows why “I” don’t dial in on the bore of both sides of the barrel. The bottom picture shows why you only dial in on the breech and the I like to go another 2”+ further in and dial this area in. You have no control of what the bullet does when it is in the barrel it will follow the bore. All I want is the bullet to leave the case strait and strait lined up with the rifling. On another side note make sure to use some type of shim or I use small brass rods in the four jaw chuck to the barre can pivot in the four jaw when dialing the bore in. I start at the chuck with the dti as far in as I can go. Then pull it back and adjust the outboard side. It takes practice but it’s alot of fun to chamber your own rifles [/QUOTE]
