Annealing after necking down and neck turning

If a case were necked down and then neck was turned and then necked down a final time, would the cases need to be annealed afterwards?

Its my understanding that the case I have in mind is necked down, necks turned and then one more neck down. I would have thought after the neck turning and before the final neck down that the brass would need to be annealed. I was told no but I thought otherwise.

Any guru's have thoughts?
 
I don't but I know some that do.

I neck down 6br brass for my tight neck 22BR. About 2nd firing I run inside neck reamer about all I do.
 
Brad,
Haven't done it,but here is my thoughts...
If you are starting with new brass, it's already annealed . So I would do the size,turn,finish neck and shoot it.
Then anneal it and shoot it for x many times you feel and repeat.
 
Not a guru on this and I agree with Tim but would only add that there is different quality in brass.
If this brass is Lapua and knowing your refined taste in brass it probably is

I doubt it is necessary but if it is another brand it won't hurt either.
 
Well I wasn't sure if necking down then neck turning was working the brass too much and then a second neck down. It was being worked three times before it's fired.

No, it's not Lapua brass, wish it was, but they don't make anything that would work for this. It would be Nosler brass.

Just wondering

This is still a project in the works, trying to get my ducks in a row.

Neck turning WILL harden brass necks - I lost a lot of cases from it when I was young. Took a while to figure out where the splits were coming from on new unfired but loaded cases. Plus you are sizing down in size twice.

When you are done making it, anneal it.

Wehen you are done making it, anneal it.




I was hoping you would reply Cat

I was thinking turning necks would harden it. But wasn't sure when I should anneal it. Sounds like that's the last step.
Thanks for your input

MY THOUGHTS ALSO, as much as it cost and as hard as some of it is to find I don't like losing one single piece.

Unless your turning for a certain diameter you only want to take off enough to clean them up about 90%, good brass only takes about .0005/.001 to clean them up.

NEVER ENOUGH


I'm kicking around some 2014 ideas, seeing how it take forever to get barrels, stocks, etc.

Figured I need a challenge, yeah right.

The cutters for neck turning are not like lathe cutters, with knife edges.

They are round plugs of carbide that the brass neck is "pulled under" (so to speak) and the excess is scraped off. This produces a lot of squish to the brass and that work hardens it.

When I first started turning case necks, I did a few thou for a PD trip. When we got there, there had been a lot of poisoning and so I brought back a lot of loaded cases.

So I left them for "next time", and when next time came, about 35% had split in a "T" shape - the split went down the neck to the base of the bullet, and then around the neck, following the base of the bullet - so the split looked like a "T" if you marked it with a pen.

I tested the necks that hadn't split and they were brittle.

So, now I anneal all cases that I turn.
