Any time you neck down brass it's a good idea to properly and completely anneal it first. Also, this is one of the few times that neck turning is required for cases to be used in factory guns. Be advised that if you turn necks with a hand held turning too without first reaming the neck inside diameter with a trued tool like a lathe reamer/turner, the pilot of your neck turning tool may be off center, resulting in cases with skewed necks.

If you have neither the equipment or knowledge required to do these two necessary steps, do not be surprised if your new brass does not work well. There is a very good article on annealing at 6mmbr.com. Forster makes a very good lathe type neck turner/case trimmer/reamer at a reasonable price.

The 6mmbr.com site can be a very slow download.
