necking up or necking down?

I have opened some case necks in the past (neck up).Generally speaking here is it easier to open them up or is it easier to neck cases down?Either way is roughly .2 so quite a bit either way.
 
I have never tried it. But I think it would be impossible to open brass up two tenths of an inch. Do you mean .02 or .002. That can be done. But not .2 Tom.
 
The farthest I ever stretched brass was .045. And that took two steps. And thinned the brass a bit. You might be able to go .1, but I think that is a LOOONNNGGG way. Tom.
 
I would have to say as a general rule,although I'm sure that someone will disagree, that it is easier to neck down,size it and fireform it. Necking up you will have to step the neck up in increments as the expander won't just slide in and out(don't forget to lube) without putting enough pressure on the shoulder to tweek it,depending on your brass (some brands are thicker than others as well as some calibers are thicker than others). Which brass are you thinking about necking down? And which calibers are you speaking of exactly?
 
Young,you got in there just before me.What I am playing with is .25 WSSM up to .358.Or .284 Win shortened to remove shoulder then neck size down (several steps) to hold a .358 slug then fire form.What would the brass serviveablity(sp) be like.It is also easer to come up with a .473 bolt face.
 
Going down is considerably easier, and has a higher suyccess rate. If your brass is too thick then you can turn the necks and trim the brass. Tom.
 
Ummm, not really. I understand the lenght and diameter now but it would make things alot easier for us to help if you would tell us what exactly what it is that you are trying to do? I would have bought a .357 rem. max. Sorry for my ignorance of Indiana deer regs.

Easy Easy I'am just thinking,With some help.And I appreciate yours.Alot of guys are building a 35/wssm.I just remember the headaches,And trying to think of an easier way to something close.I really didn't expect someone in Az to be up on Indy deer regs.As far as exactly what I'am doing.I'am just asking a question maybe someone can answer and maybe they can't.Opinions? suggestions? Welcome.
 
Just necked up 100 cases for my 358 wssm,
Not a single failure.
It is easyier to go down in size then to neck up.
When I go up from 243 wssm to 358 I do it in 6 steps.
Takes me about 1 hour to do 100 cases and that includes neck turning.
Question is you were thinking about necking down what?
They are shooting another 358 using reformed wsm brass but the case capiticy is less.
 
And also get the federal brass because the winchester brass is terible.
Let me know if you need any help.
You can also buy formed brass for D Tech.
Good luck getting Dies this late in the game.
We just got 3 sets that we have had ordered from hornaday,
took them 7 months.
 
Not this yr maybe over the winter.284 win cut off at the shoulder.You would be necking down a straight wall case from .475 or so to .358.I have never done this,but don't think it would be that bad.
 
Mrgunslinger how many dies to size the cases? What is the cost? What is the cost of the D tech form cases?No failures in 100 cases,That is impressive.
 
I use the sinclair international expander die with different size expanders.
Your talking about $175 or so for the set up plus $175 for the sizeing and seating dies from hornaday.
Not cheap.
The 358 wssm is worth it,pushing a Nosler 225 gr Accubond at 2700 FPS is really going to put the smack down on deer.

Those sound like the handgun cartridge regulations for Illinois. I can't see the reason for a minimum bullet diameter of .357! Are you sure those are the rifle regulations? If they are, I think I would get at lever action, chambered in 357 Mag. I have heard that in Illinois, they may, at some point, allow rifles in straight-walled cartridges. If they do, that will be my choice.
