I just had a 264 win mag built with a custom lija barrel for my godfather. Ive been working up a couple different loads for the rifle, and have noticed something I've never encountered before. Although accuracy is excellent and velocity is acceptable, Inserting a bullet into a fired casing is quite difficult. Im assuming the reamer has a somewhat tight neck. This rifle won't see many rounds, therefore id like to hire someone to turn the necks on 100 pieces of brass. Appreciate your help.
