.243 Lapua brass questions
anybody here shooting the Sierra 107 grain bullets in a .243 Winchester? Here's what I'm seeking. What is your exact measurment after seating a bullet on the case neck O.D. ? Getting ready to have a reamer ground, and kinda want to do a no turn neck that still fits the case neck pretty good. Maybe .0025" to .003" larger.
Next question; Has anybody here had a reamer ground with a throat made for the 107 Sierra and the 105Amax bullets? If so , what throat specs did you use, and how did it turn out?
