Cause the bolt extractor  is screwed  up  take it to gun Smith they can send to factory or fix.

This !!!!

 

As simple as fixing the bolt extractor. No big deal really.

Should be an easy fix. And Remington very much still makes ammo for the 7mm Rem. mag.

i think he's talking about 7mm RUM. ultra mag is way less common than a smaller 7mm mag.

x3.

 

also not sure what's so bad with this post? At least it's guns and stuff. For certain we have for more wild and odd stuff posted here.

Not a gunsmith.

If the extractor is at fault, why would it cycle 1 brand of ammo and not others?

The lip at the base of the cartridge may be slightly thicker/thinner with that particular brand. Allowing the extractor to work??

Makes sense.  Didn't know the tolerances were that tight on the extractor?

They shouldn't be.

Hence a problem there. Probably not extending far enough to grip and expel the cartridge, or are worn down to where they won't grip. Could be gummed up with crud, and just needs a good cleaning??

Honestly always start with a good cleaning, take the bolt all the way down and clean it. It being a 7Rum there is probably only a box or two through the gun altogether so who knows.

Not all brass is the same, there ae small variances lot to lot, brand to brand.  It can be a stacking tolerance issue, something makes it "just enough" too big/too small and causes a problem. 

That said, just because what he has works, doesn't mean more of it will. Vise versa for what didn't work.  It could also be bullet type/profile related, COAL related. 

I have a bolt rifle with removable mags. With brand "X" mags, this magazine feeds "XZY" bullet just fine, but doesn't like "123" bullet. They other brand "X" mag likes 123, but not XZY.

So who knows.

Yep Probably a combination of factors contributes to this issue. It could be due to a variety of reasons, such as the firearm being slightly dirty or the tolerance levels of the gun itself, as well as the specific type of ammunition used. For instance, Remington firearms are designed to perform optimally with their own brand of ammunition, which often involves close tolerances.

Yes.....and no....

Firearm companies make all their guns to allow for slightly different tolerances in ammo. Even custom rifles have this. I've had Remington rifles shoot better groups with Winchester ammo, and vice versa. 

The very first thing your buddy needs to do, is strip and clean the bolt assembly and see if that helps?

Yep but they all try,     companies do try to make it so their ammo works best with their guns even if it doesn't always work out that way.

Or at least they advertise it that way sometimes to get you to buy  their ammo

besides the normal cleaning, work over the chamber with a good chamber brush. a little rust/fouling there with make extraction difficult.  Doses it have extraction difficulties extracting unfired rounds?
