I have a competition 7mm die set and everytime I seat my 168 gr bergers there is a small ring near the tip of the bullet from the pusher in the die... It's not a very noticeable ring but I'm wondering if I'm doing something wrong... Obviously there is too much pressure. Am I not neck sizing properly? Do I need a special pusher for the ogive of the bergers? Why is the bullet pusher denting the top of my new bullets??
