"When you have a 2 +1 group the OAL is too long. It needs to be seated deeper.
Begin with a 1/4 turn on your seating die for medium heavy profiled barrels and half that, 1/8 turns for light "whippy" barrels.
This will not work for everyone but it will work for many by the reports I get back from people who try it. You need to shoot say 3 groups to begin with to see what you have and learn how much "you", influence the group."
I printed out John's (AussieGunWriter) reloading tips he shared a few years ago and they have been reliable for me.
