[QUOTE="swampbug, post: 3064191, member: 115992"] OK, just trying to get to the bottom line of what you are saying. I understand what you are saying about the difference between hardness/interference/tension. People can tend to use the wrong words for the same issue. Questions for clarification 1) Are you saying that using different size bushings have no affect on bullet impact. If it does affect impact, why so. And given that you have to have a neck bushing, what is the proper size? 2) It's generally accepted that repeated firing/sizing causes brass to harden over time which is a bad thing for consistency/accuracy. If the purpose of annealing is to return the brass to the original metal state/hardness, why is annealing every time a dumb thing. 3) I get that if you have a custom chamber with tight neck clearance (not SAAMI) the brass neck is being worked less and hardens at a slower pace. A) how do you know when it's time to anneal (20 rounds firing, 30, 40, 80?) B) Annealing also affects the shoulder area for headspace sizing. That sizing is only .002 or less. Are you saying that it's not necessary to anneal bc the shoulder movement is so small? 4) tight neck chambers are not a reality for 99.99% of the people reloading. Even competition shooters avoid tight necks because of potential bad issues with tight necks. So if you don't have a tight neck chamber, and annealing does actually return the brass to it's original state of hardness, why would you not anneal every time? This discussion would obviously be better off over several rounds of beer. [/QUOTE]
