Some target shooters anneal at each loading but with a hunting cartridge and rifle this is a waste of time. Like others I would see case neck splits at around 10-12 loads on the 7RM and 300 WM. This doesn't happen if I anneal before I hit the fifth load. Average brass I toss after a dozen loads but the better Brass will get a third annealing and may go 20 times for Lapua and especially RWS brass. I have not loaded the 257WM enough to have an opinion but I think I will use the same routine as the brass is so expensive. I formed several 264 PPU with poor results and I will probably anneal the next batch I try prior to forming.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
