I have had the benefit of greater accuracy with neck sizing previously fire brass (in MY bolt action rifle)than full length sizing.Unfortuantely, I was one of the few idiots who thought that the same would apply with my AR. It did not take me more than a few loads to realize that chambering issues will occur when only trying to neck size for a semi-auto. Lesson learned.
My question is this.If I want to use a neck sizing die to get greater concentricity and less runout, is it ok(are there any negative side effects) to neck size my .223/5.56 after I full length resize them? I know it's another step, but I am willing to do it if it would give me better accuracy. What do you guys think. Am I wasting my time for minimal results?
Thanks,

No need to go to such contorsions, Redding has a die that will do just that in one operation. Not only that, it uses neck-sizing bushings, which can be used with or without a TC expander ball. |

What kind of neck sizing die?
The reason I ask is that if it is a regular neck sizing die with an expander ball and a regular full length die with an expander ball then you are working the neck brass 4 times more with each loading than with a Lee Collet or bushing neck die. Annealing will help but your brass will develop neck splits sooner and the bullet grip will be affected with the neck brass harder from overworking.
Also if you are doing this to lower concentricity then you need to throw all the expander ball dies away |

"What do you guys think."
I think I don't know. But if I wanted to know, I'd try it. I think. ?? |

Woods, my neck sizing is a Lee Collet.
Ranger 335v, I don't know and try not to think too much, therefore I'm just going to do, and see what I'll know. |

coop, With out going to a custom die. I'd call forster reloading have them take a full lenght, die take out the expander ball and make the neck the size you want for your neck tension. $35.00 for die and $10.00 to cut it to the right size you want.
If you full lenght your cases your going to have to expand your necks as your going to have way more tension on them than you need to start with. Then you steel have to neck size. It all depends on how much you want to put in to this for better accuracy. |

Fantastic!
Then all you need is a Redding Body Die in your caliber. The body die will size the case body and push the shoulder back just like your full length die. It will not resize the neck which you will do with the Lee Collet.
With the Lee Collet / Redding Body Die combination you can neck size when you want to and full length size when you need to. It is a 2 step process but you will not have the expander ball in the full length die jerking your neck out of concentricity. The Lee Collet has a floating mandrel which does not move the neck alignment during the sizing process. |

| I am of the opine that accuracy comes from a good barrel, and I have a thing about accurate rifles that shoot one inch or better and put most loads to the same POI..Hard to come by, but over the years I have kept the ones that do..I full length resize all my hunting loads, and my test have shown that I gained no practical advantage in brass life or accuracy by neck sizing only, on a hunting rifle..Very little on a bench rest gun but that very little can make a difference in bench rest competition so its a good idea, however a good target rifle should a have 0 tollerence chamber and be reloaded with a hammer push die. My 6x45 could actually be reloaded without running it thru a die as expansion is so little. |

I wouldn't neck size after fl size. Why?.... If you shot a case out your rifle that case is form to your chamber. Measure the shoulder and base for reference. Then in this case you would just need to neck size, because this case is form to your chamber. But check for case length. After awhile, you probably need to fl size. But keep in mind.... When you neck size you case is form to our chamber. Make sure those case are not dirty or sticky because you will have a hard of a time. But this neck size is better or bench rest because your not out in the dirt hunting. Try this method, if doe not work I have another solution.

| Its best to try neck sizing in all calibers you load for, but keep in mind that hunting loads, particularly dangerous game loads should always be full length resized..There is very little practical difference in accuracy between the two from a hunters standpoint. I usually resize my varmint loads and target loads, never my hunting loads as function and reliability comes first and foremost. Also after a number of neck resizing you get over sized brass and need FL and then begin your neck sizing again, but depends on the guns chamber so that may or may not be. |

Although a person can be completed, but it takes time and effort can not afford to hurt, so it is best to find a bunch of like-minded Friends of the base to work with.

Germán Salazar had an article a few years back about two step sizing. He's a benchrester, so may not be pertinent to all of us, but his focus was concentricity.

I still FL size hunting ammo, calibers where I have multiple rifles (like my varmint stuff), or auto-loaders. NK sizing does improve groups for me in marginally accurate bolt rifles, so until I find a better way, or get rid of my duffers I keep plodding on.

Full Length AND neck sizing
