I read into everything when I first started also, bullet setback, pressures etc..btw you should check some of your loads after clambering a few times. Just to know what your loads are doing.

If it has a cannelure , I’m putting a Crimp on it. How much. You will have to test for your rifles.

To me after testing I would put a small crimp on all my 55/62 gr range fodder/556 loads.

My more precision like rds I did not usually. Although I did with some Nosler 77’s that had no cannelure.

Of course I’m talking ARs, no way would I on a bolt gun.
