annealing sequence question

I sure hope you do...I’ve never annealed either...but that’s exactly where I am with the steps. Everything is bright, shiny, shortened, and sized...and I bought camping propane bottles and 2 self-lighting torches today.
 
I agree with SF. It's a good idea to FL resize and trim after annealing. It's not a "rule" and if you've done it the other way, it likely won't matter a wit. But annealing may lengthen the neck slightly, will leave the chamfered case mouth very soft, and,theoretically could give you a little droop at the neck-shoulder nexus, so a post annealing resize and trim is like why the Irish wear two condoms: to be sure, to be sure.
 
Sizing, expanding work hardens brass. Doing it last would make more sense?

I do not anneal. Use a bushing die and work the necks less.

Heh. . . well, I'll admit to NOT annealing before sizing to 300 BO. The form step from .223 body to 300 neck is really pretty small; I will certainly need to anneal necks after a couple loads, but not on forming.

In general, anneal before sizing. If you anneal after sizing you'll have dangerously low neck tension; you need at least a little tension for handling resistance.
 
Sizing before or after annealing doesn't work harden the brass enough to make a difference in neck tension from what I gather. I have been annealing after every firing in the order of the OP. YMMV
 
I started annealing when I noticed my 300 win mag cases necks were cracking after the 3rd firing many years ago. Had read about this procedure from a magazine and didn't know what I was doing but would set a propane torch on the table and rotate a socket wrench with a 6 inch extender through the flame. I would count to 3 or 4 and dump the case out of the socket wrench. The socket kept me from annealing anything other than the neck and shoulder. It helped. I would anneal before resizing so my cases would be soft.
 
I am not sure it would make a big difference if you anneal every time, but I too anneal before sizing when I anneal.
 
I anneal before sizing. Makes the process run smooth. I anneal every cycle to keep every thing the same. Depending on what neck tension your running a fully annealed piece of brass may cause the buckling in the neck/shoulder area.

This is my sequence

1 deprime
2 clean (SS media)
3 Anneal
4 size/trim
5 reload

Here's a couple of my annealing machines in action:

This is also my routine. I've got an older Ken Light BC1000 and in Ken's instructions he states that he preferred to anneal before resizing. In "theory' the dimensions shouldn't change after annealing, but sizing afterwards does give the brass a chance to work harden to the same consistency.
