Since you have been on this topic for awhile, I decided to truly look into the runout on all of my .243W cases and found that my best cases to work with are my resized to .243W, Norma .308W cases with my actual Lapua .243W cases coming in as a dismal 3rd place contender behind my resized Lake City brass. I started using my Lee Collet Neck sizer again but what I found very disappointing had everything to do with the "Offset" inside the case necks on the majority of the Lapua cases. My BR acquaintance is shipping me his case neck reamer but I am wondering if it is really worth the effort. My range is good for 300 yards but I do not shoot past 200 yards and my Weatherby is as accurate as they come. I'm going to use the reamer on a batch of 50 cases but anticipate little to no improvement over the unreamed cases. What say you on this Geoff?![]()

I had my daughter shoot this group at 200 yards using the 25 yard slow fire pistol target because of how well the nice bright red center shows up in the scope. All the cases pictured are the unreamed Lapua cases...
