Why shoot a 7 mag if you not running it on the edge.

STUPIDITY has no "edge" and is simply to the fhuqking bone,as you obliviously quantify. Hint.

For even more oblivious HILARITY,cite the particulars of your "Edge" rifle and the ammo associated. Then dangle a picture of the Goat Fhuqk,to knock it out of the park. Dare ya'. Hint.

Fhuqking LAUGHING!.............

You sort of missed the boat, here. Headspacing on the belt can cause excessive case stretch through the body, leading to case-head separation, etc. Creating a false shoulder allows the case to headspace on the false shoulder and fireform, so that it headspaces on the shoulder-proper on subsequent firings.

The bottom line is that brass lasts 15+ firings, if taken care of.

Only if it has excessive headspace in the first place (on the belt). Using the shoulder instead for headspacing can help fix this problem.

Not an option for something using a case without a shoulder, like 458WM for example, but the cases in a 458WM with proper headspace will last for yonks, until the neck cracks (typically).

Loading full power 7 mag loads the primer pockets will start seating too easy long before 15 firings.

True, but that's often the case (see what I did there?) with belted magnums.

When you use a neck size die it doesn't touch the shoulder....essentially the case/shoulder is fire formed to the chamber so why the need to bump the shoulder unless you're having a clambering problem ?

Which I never had.

If you can just barely tell that the pocket is looser than virgin when seating a primer, then the case is still good to go.

One way to approach it is to only bump shoulders when chambering starts to get tight. Another way is to bump every time in order to increase consistency in case dimensions from firing to firing.

People were loading deadly accurate ammo before bumping the shoulder was ever thought of....the 7mag is a belted case and doesn't head space on the shoulder.

That's only one aspect of consistent dimensions. The other is feeding reliability.

It does if you savvy extending your brass life.

A Forstner neck size shoulder bump bushing die only touches the shoulder and the neck most dies people are bumping the shoulder with are also sizing parts of the rest of the case some.

A few years back I got into neck bushing dies....I'm now shooting a 300 wsm.
I have two micro dial seaters a Forster and a RCBS Gold Medal Match....I really like the RCBS....I have 3 sizing dies for the 300 wsm an RCBS Gold Medal Match neck only bushing die a Forster shoulder bump neck bushing die and a Forster full length die. With those 3 sizing dies I can do most anything to a case. On the bushing dies I'm not running an expander button on either die.
They're all pricey but when it comes to dies you get what you pay for....most of my loaded ammo is running .000 run out a few measure .0005 on a Sinclair digital concentricity gauge.

There is some benefit on the initial fire forming to keep pressures in and around 50 000 psi or low 'node'.

This tends to harden the case head thus prolonging primer pocket integrity.

I have started doing this with match brass and it appears to be helping so far, I shoot some mid range matches for the first couple of loadings at the lower pressure/ node.
