How many obsess over runout? I never measure it.
Quality dies set up properly will all but eliminate case run out. How many use " Competition " seating dies that costv150-200.00 or more. How many BR or F- Class guys use " Competition " seating dies, none that I know there's a reason. They all use Inline dies. Why because when you take the seating stem out and drop the bullet in it starts into the neck almost perfect as close to it as you can get. The other reason is changing seating depth at the range.
Take one of your loaded rounds seated with a " Competition " die like a Redding measure the runout now seat one with a Wilson inline die now measure runout its why I and most I know dont even bother anymore measuring it.
