Question about my reloading process

[Not_A_Llama]

Unless you can guarantee that the brass you recover is from your guns, I would size, then trim. Especially with the shoulder-indexing designs.

I tumble rifle brass twice. The first time to clean it up before sizing. The second time to clean off the case lube and brass shavings from trimming. Media does get stuck in the primer pocket but a quick look and a stab with a flash hole cleaner takes care of it. This is also a good time to inspect the case for damage.

Pistol brass gets cleaned prior to sizing and that's it. I inspect each case prior loading it into my machine.

I do the same, just never liked the idea of leaving the lube on the case. If you use bigger media, they don't get stuck as much.

I just added a case trimmer to my reloading equipment. When Should I trim my brass? Before or after sizing?

I always trim after sizing.
