    I have alot of 3rd fired 7mm mag winchester brass that had terrible neck tension issues when i seated the third load. IF I were to anneal all of these case necks would it fix the problem of erratic neck tension? What are the benefits. Would my time be better spent working a day of overtime to pay for a couple hundred norma cases.

    thanks

    Good brass is getting harder to come by these days so all the more reason to anneal them.

    The main reason we anneal is to make the brass last longer and minimize neck and shoulder
    splitting that could damage the chamber over time.

    It also makes neck tension more consistant.

    It is not so much about saving money but loading better ammo.

    Good response, but there is more. If you are using a sizer die with expander button, that could cause ilnconsistency. I would anneal them, expand them and turn the necks very slightly. Then get a good bushing die, with bushings sized a thou in each direction from diameter of a loaded round. That should solve your problem.

    Thanks, I have a good bushing die and tried lots of things but it didn't seems to matter. I have more new Win brass would I be better off annealing before even loading it or wait until its fired and the issue arises?

    It comes from the factory already annealed and ready to load. Most company's polish it before shipment, Norma being the exception.

    Jeff hasn't chimed in but we both have Bench Source rotary annealers. We consider them a bit easier to use than Ken's but it comes down to personal preference. Graffs sells the Bench Source and they have their own website as well.

    The Bench Source don't require a specific wheel for each caliber, one nice feature.

    I just bought a benchsource annealer about two weeks ago. The thing is awesome and easy to use. I hope that the machine will last a long time without anything breaking on it. It really takes the "no fun" out of annealing.

    There is really nothing to break other than the stepper drive and it should last for years. IMO, the Bench Source is better just because of the lack of multiple tables. I think the only option is the 50 cal table....I don't shoot 50's so no reason to have one.

    I might add that I anneal straight walled magnum pistol cases too, but only ocassionally.
