Annealing Brass With Different Numbers of Firings

[IDHUNTER]

I have mixture of brass that has a different number of firings on them. If I anneal all of them will they all be consistent or will there still be some variation between the ones with different firings?

And just to clarify, it's all the same kind of brass (Norma)

Annealing, if your process is consistent, will set the hardness of your brass to about the same value. The number of firings being different isn't good but bullet insertion Force should be more uniform after annealing. I once noticed a big difference in bullet pressing force within a batch of once fired RP brass. Before I loaded a larger batch I annealed them all and the variation in force went down.
