How thick are your necks after this?

He might be asking why you felt it necessary to anneal the brass.
If it was unfired, there would be no need to anneal. If it had been fired in a normal chamber you'd be close to size already. Even in a TNT, you are only talking about .020" or so.

I always had better luck sizing up, not down. You do have to neck turn the lapua 243 brass.

Re: !st try at making 260 brass

I am not turning necks I dont need to. I shoot a 140g Berger VLD the necks are all .297 or less.

I am using LC match brass in one rifle and lupua in the other both 308 necked down.
