It doesn't seem to stretch all that much compared to rifle brass. For casual shooting, .357 brass will wear out and need to be discarded before it will get too long to reload.

Re: trimming 357mag brass
As I understand, the only real reason to trim them is to guarantee consistent crimps. Even then, it is usually trim them all once, and they are good for the life of the cartridge. Most of us don't trim straight walled cases. I can live with crimps being a little inconsistent, as long as it is somewhere in the canelure.

Re: trimming 357mag brass
I have been given once fired brass with mixed head stamps. In that case, I did trim each of them just to make the lot uniform. But, I don't normally trim them.
I organize my cases (from factory ammo that I bought) in their original groups of 50. Then, before I reload them, I re-adjust the Factory Crimp Die for each lot to maintain a consistent crimp across the inventory. It works for me.

Re: trimming 357mag brass
I'm kinda new at this, but for me I've found that if i separate brass to spec [1.280] +- .002", load them first and any shorts ones I readjust die to get a crimp.
Anything much longer i trim, I hate to crush cases

Re: trimming 357mag brass
I as well sort out the shorter cases. I use them but I like to be close when seating bullets rather than having some in the case farther than others. I only trim the longer ones back to what I have the most of. Al

Don't worry about getting older and still doing stupid stuff. You'll do the stupid stuff as always, only much slower. Hold my beer and watch this.......
