[QUOTE="cajun, post: 2115357, member: 9772"] 8 There’s always more than one way to skin a cat. Different techniques can also work better for different disciplines. For example prs guys might shoot 200 rds a match. If you need to move your seating depth .004 every 50 rounds thats not going to work very well. I think also there is a resistance among some people to open their minds to a different way of doing things. In your example of moving the bullet .004 every 50 rounds if this wear was linear for the life of the barrel you would be moving the bullet almost a quarter inch. I found this article to be very interesting.
