Neck Reamers - good idea or reduces lifespan?

I bought a neck reamer for my .308 and 7mm Mag. Seemed like a good idea. But I've noticed that it stretches out the neck, and I'm now concerned this practice may reduce case life.

Any input would be appreciated on if reaming out the neck improved accuracy or something else.

Thanks.

I you are stretching the necks they are too tight for your reamer size. Get an expander just smaller than your reamer. Expand the necks with it, ream, and then outside turn if you want perfect necks. It is not necessary in most cases and can be counterproductive if done wrong or to much is taken off the neck. You neck size on your chamber needs to be taken into consideration before turning also.
