A friend and I have had a running conversation regarding how to best approach consistent bullet release. Dan shoots 1000 BR and is very meticulous as to how he approaches case prep. We both agree that consistent bullet release is part of the equation for low ES and subsequent tight groups. He believes that leaving residue in the necks of fired brass is the best approach. He thinks sonic cleaning, tumbling or even using a bore brush in the necks is a bad idea. He sizes using a S bushing die and doesn't do anything about the residue inside the necks. He is about to anneal his brass and says he will have to fire every case once to coat the necks with powder residue before using them in a match. I argue that if the necks are clean by using a sonic cleaner or after annealing there is no need to shoot each piece of brass to coat the neck walls. Dan argues that super clean brass is bad for consistent bullet release. I realize that the load might have to be tweaked because of the increased friction but I think that a clean neck vs a fouled neck would cause no difference in potential accuracy. What about running a bore brush into the necks to remove excess residue? What about tumbling brass? Wouldn't these methods also result in consistent bullet release? I think you get the idea. Obviously this is not something most of us worry over with our hunting rifles. Maybe we should? Consistency is important, which approach is best or does it matter? Would love to hear your ideas.
