Thread: Resizing inconsistency - Am I missing something

You can have the best dies, press etc, but if your brass isn't consistently annealed (or not annealed at all) you will have inconsistency in your sizing process. It might not happen in the start of your brass life but will show itself later after multiple firings.

Just another variable to consider. There are quite a few youtube vids about annealing and sizing consistency

Thanks mate I thought that may be a factor, been looking into the AMP Annealer but can’t afford one atm. I’ve watched just about every video Erik Cortina and F-Class John post so am definitely all the way down the precision rabbit hole 😂
