Problem after annealing

[josebd]

.308 Lapua Brass,after I anneal the brass then full length resize with my Forster die,it seems like after a few it starts scratching outside the neck on the brass,I can clean and polish the neck,does good for a while then starts again,anybody else run into this?necks are chamfered inside and outside.

Sounds like a rough spot thats picking up brass, building up and scratching

My experience is that your necks are to soft. If you do not remove the brass from the neck area of your die it will only get worse as you continue to size. I at first thought that it was caused by carbon on the necks, but, later determined that it was in the anneal.

I was annealing after each firing,do I need to wait till after 2 or 3 firings?

I would clean the die also. Check all your cleaning methods, die and brass. Sounds like you have something caught in your die. That would be my start to figure it out.

I had scratches on brass caused by the dies. Fixed dies, no further problem.

I have cleaned and polished this die 3 or 4 times,with 0000 steel wool,spray b12 through it to clean it out,then flitz

How did you fix the die?

Are you cleaning the brass or at least the necks before sizing?

 

[Iowa Fox]

What are you using for lube on your brass & necks?

I have had the same scratched necks and fouled dies when running NEW Lapua brass through a die. To stop the problem, I put New Lapua cases in a vibratory tumbler using walnut media for 4-6 hrs prior to sizing them. Or, tumble them until the annealing color starts to fade and the necks won't scratch or foul the die.
I now, also, tumble cases for a while after annealing and haven't had any problems.

Thanks guys

Tumbling after annealing will cure this. Get the die cleaned or polished up too.

 

[josebd]

I have cleaned,polished the die twice, I can see some vertical scratches on the neck of the brass,but real faint, can' t feel with finger
