Is there any disadvantage to annealing after every firing?

Not with good equipment and proper annealing practices. Is annealing every firing going to show you noticeable accuracy results, no. Over looking the differences from case to case, I would venture to say accuracy and neck tension losses won't show to be measurably different until after at least 3 firings. But if you want one less thing to keep track of, want all brass always on the same level, and do it inside the proper methods of annealing, annealing each shot may be a good choice for you. One example would be, I may only have 50 pcs of brass for a given rifle that has been fully fire formed. I go out and shoot 30 dialing the rifle in for hunting season. Now I want to load those 30 back up, but don't want the bother of marking them IE (fired 1X since annealed) but rather have all the 50 fresh annealed for my hunts. Annealing each time just eliminated this one variable.

What is an Induction Billet Heater and How Does It Work?

It's not that the seating depth is changing loading to loading. The seating is varying .002 seating in the same batch. I have to go back through and reseat the longer ones to match. I still vary a full .001. I'm accustomed to the seating varying way less than a full thousandth. It usually just shades to one side or the other of the thousandth mark it's on. I'll figure out where I'm going wrong .

Shrek, forgive me for saying this, but I hope you're not gettin' wrapped up around the axle about seating depth. If you've got a good shootin' rifle and have found a decent load for it, I seriously doubt you'd ever be able to statistically measure any appreciable change in point of impact from a .002" variation in land engagement.

Believe, me, I get the OCD kickin' in too, and sometimes, 'little things' can make me wanna crawl up a wall when tryin' to achieve loading a "perfect" round. But after a while, ya kinda figure out what warrants the extra attention to detail, and what gets lost in the 'white noise' of actually shooting. In other words, shootin' a big boomer 7mm at distance, you will likely not be able to tell any difference of a couple thou. in seating depth. There are simply too many uncontrollable variables that will far outweigh the affect of POI change from .002" difference in depth. Heck, a miniscule 1 mph wind call error at long range will affect your POI enough to mask many load inconsistencies. So, for all intents & purposes, you might very well be obsessing over something that will make absolutely no difference on target For perspective...

Again, I can definitely appreciate the drive to make "perfect" ammo, so I'm not critiquing your motivation! Rather, offering a sobering viewpoint as to whether the effort is worth the reward?

To prove to yourself if .002" seating depth variation matters, test them! Take a batch of rounds with c.o.a.l. variances, and segregate them according to your measurement. Of course, you'll want to have previously sorted all of these bullets according to ogive measurement and overall weight, so you truly know what the cause in variance is attributed to. After all, you are seeking "perfection" type tolerances, so take EVERYTHING into account and leave nothing to chance!

Test each group, round robin, at two targets... one for the -.002" short loaded, and one for the set length rounds. Note any differences.
Also, you could shoot a few five round groups, with one round of the 5 being .002" deviant. Have a buddy keeps tabs on which is the 'mickey' when he hand you rounds, one by one. That will ensure that you aren't mind screwing your own results. After five rounds, see if you can tell your buddy which round you shot was the .002" deviant?

My point is: if you can tangibly measure a difference between the two groups, then I'd say ABSOLUTELY address the issue! Rock on, embrace the joy of your OCD, and seat every bullet as perfectly as you can!
If not, then don't sweat it & have fun...
