Resize, Prime then Trim? Or is that wrong

[DMW1116]

I trim them prime because my trimmer uses the primer flash hole as a guide. I messed up and primed some 30-30 before trimming and rather than chance depriming them I bought a Lee Quicktrim die. That worked but the lock stud and trimmer is faster and consistent but with less flexibility on case length.

Hello - this will be my first batch, so please bare with me!

I have some once fire .308 brass that I have already resized and deprimed. I have not measured the brass (awaiting delivery of calipers) and my primers were delivered today.

Would I be able to prime this resized brass then trim (if required following measurement), or am I better off waiting to trim the brass then prime?

I have not gotten round to buying a manual yet. I will be getting one prior to loading any powder & bullets for sure.

Thanks all.

Trim them before priming and clean the primer pockets, then tumble polish, then prime, and load, that's what I do.
