[QUOTE="Mikecr, post: 2970783, member: 1521"] That's true. I have nothing against frequent annealing, but I suspect a lot of reloaders get the impression that there is an improvement -for sure. I don't want soft brass. I want the hardest brass I can get. Then with minimal clearances and sizing, it stabilizes & lasts forever. MY best die is my chamber, which my hard brass springs back from. On pressure raising: You may notice that new brass produces lower MV with a given load than fully fire formed. This is because new brass expansion acts to limit peak pressure, where fully formed goes right where it's been(against chamber walls) quicker , absorbing less energy. While this may seem counter intuitive, the fact is: even hard brass wants to go where it's been. Softer brass expands even easier than stretched hard brass, absorbing even less energy from peak pressure. This in itself is not a problem, but a difference, and once you choose and develop with that difference, you're a slave to it. Hopefully everything around that works out for you. It doesn't actually work best for everyone. Try convincing this guy that he should anneal: [URL unfurl="true"]https://bulletin.accurateshooter.com/2023/12/sunday-gunday-amazing-record-setting-6-bra-1000-yard-rifle/[/URL] [/QUOTE]
