Got an AMP annealer and want to make sure i understand steps and frequency.

I deprive and clean brass first....then is it size, any prep, then anneal? Or other?

And how often would you anneal, and does that differ by cartridge or brass brand? I have 3 cartridges....6.5cr with Lapua brass, 28N with Nosler Brass, and 280AI with Nosler Brass. I currently FL size bit am considering neck sizing only until brass won’t chamber.

Any input is appreciated.

I anneal after cleaning, then FL resize. It will give you more consistent base to datum results. I do not neck size, as I see no advantage in it.

I FL resize, tumble, trim (if needed), chamfer in/out, anneal, then load.

I want consistent neck tension when seating a bullet, every time. I do not want to work harden the brass in the least before I seat bullets.

I anneal every time. Again, for consistent neck tension as the last step before I load.

It has worked well for me.

As much as I hate to admit it, annealing Everytime produces the best ES and SDs, and prolongs the brass life the most. While it may be difficult to detect, there is a degredation of brass consistency via work hardening with every shooting. I say I hate to admit it as I swore I would never go through that trouble every loading and I lost a bet with a guy who proved it's value to me. I'm a little hard headed that way!

If you do not have an AMP annealer how do some of you anneal? I am curious if one could anneal with just a propane torch??

Research Salt Bath method. Appears it would be a better process in maintaining temp than flame method.
I just started using the salt bath method and once you get your salts up to temp, it is very quick and very consistent. The problem I have with a torch is that the temperature can vary greatly on this brass. Torches are fine for heavy metal that changes temperature slowly, but the difference of a half a second on light brass could vary the temperature by quite a lot. Maybe it won't matter, but consistency is what we are trying to achieve.

I'm using the Ballistic Recreation salt method. It's pretty slick, doesn't cost much and once it's up to temp I can do 50 cases in about 5 minutes or less.

I was/am under the impression that one should anneal before sizing so the brass is the same hardness when sizing???????? I do anneal every time.
