Resizing as last step undoes benefits of annealing?

Ideally I'd prefer not to anneal, or reload for that matter.
According, to the man at AMP, annealing the same case twice (as long as it cools in between) has no detrimental effect on the brass.
If that is the case then your statement above makes perfect sense.
Yes, but the issue is the scaling that annealing causes. FL resizing AFTER annealing helps break up that scaling, and gives more uniform neck tension.
Yes, and that seems the accepted way of doing it. But, taking the scaling out of the equation, a second anneal (after all the sizing, neck expanding, TTL,) should equally give a uniform neck tension, no?
I'm not being contentious, just interested in the whole discussion.
I note that in another thread, a reloader is seeing very sooty case necks and a lack of obturation is suggested as one reason.
Whilst the AMP data suggesting that re-sizing after annealing gives consistent neck tension, might annealing at final step better ensure case obturation?
I'm heading in that direction with my .223 which also has sooty cases.
I'm hoping that a one time annealing further towards the head than normal may allow the case to expand out and close any gap.
I do not even think a guy with a deer rifle needs to worry about annealing unless he is working the brass hard to re-form one case into another involving multiple processing steps .
Scores where not improved across the board when folks started annealing to the point that could be cleanly seen .
A case that lasts 10 firings derstalking , varminting and especially lamping - without loss , its a minority !
Far better imo you reduce the work via moving the brass the least amount and neck sizing with a bushing that gives just enough grip rather than a std FLS die one fits all with that awefull ball expander prosess of the factory die. Bumb the shoulder if and only if needed.

Agreed. Neck tension is apart of the accuracy equation, of no doubt. But not usually discernible except at extreme ranges; far beyond normal hunting ranges.
While obturation can be caused by overly hard case necks, usually it's a low powder charge, with hard case necks just adding to the symptom. IME anyways...
very very little in long range target shooting has much at all to do with shooting deer to be fair , its mainly folks comming from target shooting who think different . Personally i have done both but i have done much more hunting for far longer . Target shooting helped me with wind reading thats about it!
I still prefer using chamber type hand dies in an arbour press and a few other things i learnt along the way but Annealing is way the most needless ( and costly) thing in the loading room of a deer hunter .

For my OCD I only anneal my 300prc lapua after each firing then resize then clean trim if needed and repeat .Its just my way and my results down range !it tells me not to change my spots lol.
Pos' its way over the top but what other sport allows you free time in the shed alone. Bliss is a reloading bench
6.5 creed was to be every 3rd firing but as I have lots of once fired brass Lapua its still not there yet .
Cheap brass is just grass fodder like PPU in the .270 well I won't cry if I lose a case out of the high seat all that gets is clean fill repeat.

In all honesty if you (personally) can not demonstrate a difference in accuracy between the two methods then it is an exercise in mental masturbation
The case life may be marginally better, but occasional annealing is fine to preserve brass elasticity for the masses

As someone who has spent time competing and stalking / shooting other quarry . IMO and experiance , while a reasonable expectation on a case use would be ten ( depending you can get more or less even far less ). Your generally going to loose a case used on your targeted quarry before it gets near to 10 firings . out lamping its going to be a far shorter time . So give the decision to anneal serious thought as it has its cost in time and capital .
Ok its been over 15 years since i set foot on an official range and few at that time anealled ( those that did tended to sit the cases in water , heat the shoulder neck by hand torch). How much have scores actually increased i wonder ? I dont recon its really deterrable in competition , be very surprised if its better by 0.25moa , itself of no real relevance to the hunter / modern long range hunter (often refered to as " the p.poor stalker " LOL .
