Re: Brass Sizing Question

Bumping the shoulder back .001"-.003" = a F/L sizing die. Neck sizing = neck sizing only which does not touch the body of the case.
Redding, Forester and Hornady make bushing dies, which allows you to vary your neck/bullet tension by using different sized bushings. Bushing dies can be had in "neck only" sizing or F/L sizing. You decide which one you want. For bolt guns, many people get a neck only sizer and the buy a body only sizer (From Redding) . For autoloaders, it's best to buy a F/L bushing sizing die, which F/L sizes every time.
Even If you neck size only, you will need to F/L size after 4 or so firing. A F/L die will bump (resize) the body and shoulder. If you want to bump you shoulder back .001"-.003" for your rifle, you set your F/L die to do that for your particular rifle's chamber.
For my precision rifles, I decided to use a Redding bushing neck only sizer. I also bought a Redding "Body" only" die. This "body only"die sizes only the body of the case (doesn't touch the neck) and will bump the shoulder to however you adjust it to size in your press. Fired cases get a sizing in the F/L body only die. They then get neck only sized with the neck only bushing die. After being fired, the cases get neck only sized and fired 3-4 more times. After the 4th firing, the cases go into the F/L body die only again to bring the case back to original dimensions. After 4 or so firings, the brass cases will stretch to the point where they will stick or be difficult to chamber in your rifle.
