Best die to size the neck and bump the shoulder?

[mattri]

Looking for a die to size the neck and bump the shoulder back .002" but without working the case too much.

Thinking about having Lee make a custom Collet die based off of some fired cases.

I've always liked the collet neck sizer, and have the time for them make a die to my chamber.

If I go this route I'll probably use a body die to bump the shoulder back from time to time.

Ideally I'd prefer one die to do this but the full length sizers seem to size the body way too much.

Thoughts?

Sounds to me like you want consistency with very little brass movement in your resizing every time, which is a good desire, from which I suggest to have a matching die and use it every time.
My recommendation is to have a custom F/L die made to match your chamber, and you will get everything you want every time you size and reload the case.
Bumping a couple times, then body die, then more bumping, then body, etc., etc.,.... is not making the exact same ammo ever time, and is depleting of the brass' elastic memory - IMO.

Good Luck

If you want to resize the neck and shoulder to head length only, Forster makes that die --Bushing/bump/neck die or a name like that. I have 2 of them and they work fine.

Mattri -

Howdy !

I've read where LEE is currently not doing any " custom " work.

Hornady makes a dandy shoulder bump/bushing NS die, and they accept Wilson bushings.

Forster bump die and a set of Redding comp shell holders and you are in pig city.

Harrell's Full Length Bushing Die !

If they have the caliber you're using. Call.

Every caliber they sell is not listed on their internet site.

Get Jim Carstenson at JLC Precision to either build a die or custom hone to fit. He can use a redding body die and convert it to FL bushing with perfect body sizing for under $100

IF you don't want to work the brass too much, then go to a tight-neck or minimum-neck chamber. And, Full Length Size. Half measures will only bring on a series of never ending headaches.

do a search on this forum for 'JLC' or 'JLC precesion' for an article.
jim is a very quiet fellow. he wont talk your leg off.

Great replies thanks.

I still use forsters BB NK die for a couple calibers and their use is essentially to bring the necks down in two steps (without sizing the case) as I don't like to size the brass more than once in a FL die if I am needing to bring the necks down more than .005" of what they currently are.

This can be helpful when using a SAAMI chamber and you still would like to skim cut your necks for concentricity , as you will find in order to achieve a given neck tension you may have to size the necks down as much as .008" , ultimately this would require sizing the neck in two steps.

I personally like to leave myself a bit of clearance in all directions of the case and it's relationship with the chamber , be it trim length , base to datum , dia. at the base , dia. below shoulder junction , and the neck walls..

There was a time when I played with only neck sizing , partial neck sizing and for me it led to coming rite back to FL sizing at one point or another... The problem with that was by the time I did notice I needed to FL size the brass needed A LOT of sizing in one step.

I should note that I have had some rifles that when shot with mild target loads would seemingly shoot endlessly without FL sizing using Wilson dies , however when I stepped on the gas on those same cartridges they would show signs of pressure via sticky bolt etc . When in reality the load was still acceptable pressure wise but the brass was in need of FL sizing.

I keep a log of all my old targets (some of them not nice lol) and I can see that if there's something I've changed it is visible on the paper to go back and compare.... Calculated FL sizing has been one of the single most improvements to both accuracy and case life for me according to this.

Last night I was doing a bit of surfing on youtube searching for a Video of Boyd Allens use of the PMA tool adjustable lock ring (which I've now just received thanks Pat) when I stumbled onto a video of a fellow claiming to show the ins and outs of benchrest loading techniques .... He had the rite equipment such as good quality dies and even so much as a fancy instant indicator die from redding.

Whats interesting is he showed the steps on how the instant indicator die would show him how much he has bumped the shoulder etc. and he sized a .308 case in his redding FL die that was according to him "Screwed down as far as it would go" (he was also using hornady LNL inserts but that's for another story lol) When he took the sized case and put it into the indicator die he had found that he had actually lengthened the base to datum by .003".... He seemed befuddled by this but shrugged it off as fine because that is as far as the die will screw down.

He started out fine by knowing the dimensions of his fired brass and also knew that he wanted to size his brass so as to get a specific amount of bump , where he went south was when after FL sizing the case and he found it to have actually lengthened it he dismissed this as "That's as good as it can get because the die wont go any closer to the shell holder" .

When in reality what that told him was no , that is not as good as it gets you've actually just stumbled onto the fact that you either need to try a different shell holder or have one ground down (by aprox. .004" as he already knew that's how much the shoulder moved forward during sizing) Or have the bottom of the die touched up by that amount because the shoulder portion of the die is too high up to make contact.

It also tells him something else , when you size brass it doesn't magically disappear , it goes somewhere... In his case it went the only place it could and that was up towards the shoulder and then stopped when the shell holder could not allow the case to go up any more.

The point being that if you have precise measurements of your fired brass you will know what EXACTLY is going on with your sizing process no matter what you choose , be it neck only or FL.

Good luck.

Ps: I'm going to give a shameless plug to Pat at PMA tool lol , ordered the adjustable locking die ring and it was at my door up in the frozen north in about 7 working days.. A beautifully crafted piece

Body dies have the same effect as a FL bushing die with the bushing removed. They size the body, and can be set to bump the shoulder. If you just bump the shoulder and size the neck, and shoot reasonably warm loads, you will find out why bump dies are generally not used in short range benchrest. Case heads swell, bolts get tight, and if there is a variance in bolt close effort within a group, it will be enlarged. That being said, if your rifle has a factory chamber, the combination of a Collet die, and properly adjusted body die can give very good results. Bushings do not do their best work when fired necks are quite a bit bigger than sized. Also, I am not aware of any neck die, that can bump a shoulder. Obviously Forster makes a die that does both, but they do not refer to it as a neck die, but rather as a bushing bump neck sizing die, to make the difference clear.

The WTC die can be utilized as a neck die, and also bumps the shoulder.

The Forster is a neck die that sizes the neck and bumps the shoulder - it does not touch the body at all.

I have a Forster BB NK die in 6.5x284 that will indeed do a very slight amount of sizing at both the .200 line and just below the shoulder junction when setup to bump .002" on a particular rifle... That told me the chamber was oversize and the measurements of the brass post firing confirmed it.. So to say that it will do something is relevant to what you're working with I would say.
