How many firings are people getting before accuracy starts to drop? With what brand of case? I'm currently upto 4 firings with Winchester cases and accuracy is still good, but have lost a few cases and am going to get some more but not sure what brand

After 2-3 firings you really need to anneal the case necks, some would say after every firing. Brass in the neck becomes hard after repeated firing and working in the die. It’s looses its spring back potential and you end up with variable neck tension and accuracy suffers. You’ll also get split necks. There’s a guy on TradeMe offering to do induction annealing, and I think on this forum also, can’t remember his handle

I’ve had no problems with Winchester brass just get it anealed and check for case stretch. I will probably get some Norma when I replace this lot.

Will look into aneling. Used to use Norma brass and bin it at 4 or 5 firings and get new brass but married with kids now I'm looking for my best bang for my buck haha have tried aneling ages ago with poor results
