Two suggestions.
1. Examine barrel with a borescope. There is a $50.00 one on amazon that so far is working fine for many. (I like mine.)
2. measure and record the bullet to lands seating length and select a bullet that will do three things.
A. be within 30 thousandth of the lands, B. Fit in the magazine, C. go at least one caliber (.264) into the neck.
For me there were three bullets that I have that do this: Sierra 120MK, Sierra 120 Pro hunter and Speer 140 Hot core, all three give excellent accuracy in my firearms.
