I maybe about to show my stupidity here but hey, won't be the first time.

I've always full-length resized. But I'm going to stop full-length resizing and go with just neck sizing. But part of the sizing process has to do with the case getting deprimed. How do I accomplish depriming if I only neck size? Seat the depriming pin out MUCH further?

Thanks.

Yep. I'm hoping you already know that you have to use neck sized cases in the same rifle they were fired in. In almost all situations this is true.

Nobody, Buy you a regular neck sizing die and it will punch out your primer just like your full lenght die does. Put your full length aside and you might need it sometime. When I started reloading, I full lenght resized and I quit too., When you shoot your casing in the same gun You don't need to full resize. Carl L.

That is the wonderful thing about shooting sports. The ready-made excuses to buy more stuff. :grin:

Back in the old days some people tried what was called 1/2 neck sizing. This is done by backing your sizing die out of your press a distance equal to about 1/2 the length of the neck. Then screw your decaping rod in till it pushes the primer out. You will end up with a step on the neck of the case. This sizes the case less and only half of the neck. We might want to ask what are you wanting to gain by neck sizing?
If you decide to go with the neck sizing there are three ways to go.
1. the collet type die from lee
2. regular neck dies from a lot of die people
3. bushing type neck dies
Each of these has it's own pros and cons

I sortof do what yankee described. I do a lot of loading for an m-14 and a garand. I strip the bolt and rifle down then use my chamber and bolt as a sort of case gage. I take a hadful of brass and back off on the sizer some then start sizing and trying and moving the die down a little at a time till the bolt closes easily with no friction then I lock the die down. It is very important on any sem auto to make real sure the bolt can close easily but then you don't want excess play either. That will over work your brass. The way I do it there is no excess room for stretch but also the case is a guaranteed fit each and every time.

Ok, thanks.

As I mentioned earlier, I'm going to neck resize only. Is it ok to put some sort of magic marker on the neck of the case in order to see how far down the neck the resizer die is going? That magic marker stuff is VERY adherent and I don't want it building up on the inside of my die.

Thanks.

Just use a magic marker. It comes right off with hoppes. Really you should be able to see what has been sized. Just took a hundred cases down .002 and that could be seen.

I prefer to "smoke" my brass with a wooden match.

Hello Nobody,

I see no problem here. Just dip your case neck in graphite before neck sizing. It will produce a white ring around the neck that tells you how far down the neck you're going when sizing. I remove the primers as a separate operation. Lee sells a punch and base set that allows you to tap them out from inside. The reasoning behind all this is that a case that's been fired in your rifle should be virtually concentric when you remove it from the chamber. The secret is to keep it that way. Best wishes.
