When to anneal.

I've got a bunch of several times reloaded brass that I have been neck sizing and I am contemplating having them annealed.
They have all been decapped but would I be better sizing them before annealing or after?

Thanks

Anneal then resize.

Anneal first then size

You get the benefit of less springback, which can be as much as 1.3 thou on unannealed brass

And your first resize after annealing is your best chance to measure your true neck tension

Yeah anneal then resize. i once did a test to see if i got any better results on target and i couldn't see any (annealing last before seating). I did notice bugger all neck tension which isn't a great thing as some
felt different as i seated them (harder / softer). I get a more consistent feel if i had full length sized after annealing.

The bit i hate is chamfering. Its needed but that is the biggest contributor to neck tension variation IMO.
Try a batch not chamfered vs chamfered and record your MV. I put it forward that it makes it worse

Get a Sinclair holder. Whack it in and run it thru your 18v drill. No drama.
