Help me pick my new dies for 7mm Rem Mag

[Timbco84]

Hello, I'm using a RCBS Rock Chucker Press currently with standard RCBS FL dies. I'm having a problem with the expander only opening my case necks up to .281" which is a little to tight for my neck turning pilot to fit in for one, and I'm not sure, but that seems like excessive neck tension for a .284" bullet, Please by all means correct me if I'm wrong.

I'm looking to purchase a die or set of dies that will allow me to...
1. Push the shoulder back .002" after firing, this is a hunting rifle and I need the peace of mind that my rounds will chamber no matter what.
2. Size the case neck to a given diameter that will allow me to control neck tension and use my neck turner (looking like a bushing die of some sort).
3. I would also be interterested in what to expect consitancy wise loading Nosler accubonds with the standard seater die my FL die came with. I am loading to an ogive measurment for specific set back from the lands, not Case Over All Length. Is my seater die going to fit my needs or is there a better alternitive out there.?

Also, I know forster makes a "Bushing Bump Neck sizing die", my question is this, if your sizing the neck and just pushing the shoulder back, is this die going far enough down the body of the case to control where the brass being pushed ends up? Is this basically a FL die that has the ability to shove the shoulders back farther than your typical FL die?

Thanks for the help.

Becuase you're planning on neck turning, and like MikeBooshay stated in your turning thread, unless you know what diameter your neck is reamed to, you may be setting yourself up for failure. My point, stay away from Redding type s dies, their bushing is beveled and could result in cases with the dreaded donut. And because you've turned the neck's once, you may be done. I heard Forster's are more forgiving, don't know firsthand.
Hopfully someone else will chime in.
Don't have a clue what this "Bump" die is all about either.

Redding FL bushing could be an option.. I'd just keep on using your standard seater.

The type s bushing works for me. How much you bump simply depends on how far down you screw your die. You can get a set of headspace(bump) gauges or use your rifle to determine how much you want to bump your shoulders back. I like to set my sizing die so that I have just a little tension when I lower the bolt. If the bolt falls easily into place IMO I'm working the brass to much. I think if your expander ball is bringing your neck to .281 it is doing its job just make sure you chamfer the neck so you don't damage the bullet jacket when seating. For a .284 .281 gives you .003 neck tension I would recommend .001 or .002(for super precise long range) but .003 should be just fine.

Your FL die is going to size the case neck to fit a bullet, which is too tight for a neck turning mandral. You need to buy an expander die and the correct size mandral. Sinclair makes the one that I have, and K&M makes a good one. The dies that you have should do fine, this is not their fault. I don't know how to post links, but Google accurateshooter.com or Varmintal and search for their info on neck turning. Lots of good info there. Lightman

I ordered a K&M Expander so I'll see how it goes when that shows up. You make a good point about my current dies. I was trying to make a 3 step process a 2 step process...not going to work that way. Your right, those links you posted are filled with awesome info, I will be passing those along. Thank you.
