RHINO Report post Posted September 22, 2016 try using a concentricity gage. Sometimes they are tough to find the sweet spot on seating depth. I start .010 jammed and the back off .040 then .080 and the .120. You will see that one of those will be dramatically better than the other. Then I will go in and out from there. My rifle loved them jammed and then really loved them jumped over .120. Share this post Link to post Share on other sites
