[QUOTE="Bullet bumper, post: 921551, member: 17844"] If crimping is improving groups and you don't actually need to crimp then I would look at increasing neck tension from your neck sizing die or if that is already quite adequate , changing powder to a slighly faster powder . Also I would check the bullet runout after seating to see if the seater die is doing a good job . Another thing I don't like about crimping , especially factory type crimps is it works the end of the case more and work hardens it . That increases the chance of neck spliting . I always find that softer necks shoot bettter than hard necks in my bolt guns but that does not mean for sure it wiil do the same thing in all . [/QUOTE]
