Annealing + Trim Brass — Which Should Be Done First.

[kennicka]

I am with the majority of the responders in that I size and trim after annealing. Lots of good answers here!

I think, at least in my case, the whole thing revolves around sizing. Annealing, should always be done before sizing. You want the brass soft enough for the sizing die to do it’s job. Then trimming should be done after sizing. Sizing generally expands the case, so you would not want to trim a case before it’s sized. This would mean that annealing would be done before trimming, at least in my mind.

I trim dead last

Lot of good and different answers which to me means nothing is concrete if it works for you do it. And I dare say that I bet a few after reading may alter or try doing it different just to see. Which I hope is a positive for this thread
keep it coming

Start with a fired case, squeeze it down, expand it.
Annealing before or after sizing might depend on how much you are squeezing down the neck (FL die, bushing die, body die) and then expanding the neck or just sizing the neck with a LCD.
Different methods work the neck/shoulder differently.
