Thread: How hot?

How hot and safe would you call this?
Have laddered up to this point twice was going to go more till got better slap an sticky lift but I forgot till I was there and seen was same as before.

No sticky lift or extraction
1.5thou head expansion over new brass unformed, this case has been formed and fired twice now at that load.

Little man didn't want to let the go. ..
So people add you $1.50 interested to see that's all so don't be shy

Primer cratering, ejector marks. Possibly some leakage around the primer and 1.5 thou CHE? Not sure I entirely get the question.

It could settle on that load as the case has formed properly. If it chambers easily without sizing or trimming and shows no obvious signs on the third firing, she could be sweet. May not be in a few months tho.

What sort of extractor Abe?

SlopPy firing pin hole. Made in America?

It's Remington 700 bolt are bit sloppy in the pin hole
Sako extractor I put in it as well not that flat tho is flattering off would only be gr or 2 away from sticky

Chambers easy as again, no gas leak just looks like it in the photo.
Here's a photo of one 6gr less. . ..

Looks similiar to a few of mine that i got in load developement so im also interested. I had no cratering or sticky bolt lift whatsoever, this was the only pressure sign.

Note my brass is a lot dirtier haha, should probably tumble them one of these days...

Only since this is all new lol.

Little things are easy to get wee slaps when is right near the edge, moisture in chamber little hotter day, longer strings getting things hotter when they sit in there etc

Where is the RE off the REM gone

Neckshot, the head stamp is partially gone and the loads are not hot? You sure about that? Lapua brass to.

Loads not hot ??!!????

Dude, if that is what is happening to your brass your loads ARE way too hot. Lapua cases are generally harder/tougher than most other makes. (i.e. - good.)

Brass swell into the plunger ejector hole, then getting sheared off as you rotate the bolt face on the jammed case.

the primer 'cratering' is caused by the EXCESSIVE pressure pushing the firing pin tip back as the cartridge discharges, during peak pressure.

These are the main fixes for these conditions:

1. reduce your powder charge or neck tension, or take the bullet out of 'jam' condition.
2. Go to a custom action or bolt with a reduced diameter firing pin tip.
3. use primers with a harder 'cup'.
4. Increase the force of your bolts mainspring.
5. Norma brass is notoriously soft compared with other makes, reduce your loading intensity.
6. Go to a stiffer/bigger custom action that is better able to handle the higher pressures.
7. Reduce your loads. velocity for velocities sake is not always a good pursuit.
8. All of the above.


(9. ensure your medical/income protection insurance is paid up if you want to keep pushing the limits of a bit of brass that is the main think separating you from 60,000+ PSI of 'nasty'.........)

File a few thou off the firing pin!

my Remington does the cratering too.(on pretty much any load)
the edge of the primer is still round, not flat. the extractor mark could be from soft brass.
I also had factory superformance ammo put extractor marks on cases, but probabley not the bright.
I don't think its too hot, but the extractor marks suck. check the velocity isn't too high.
if it wont last five firings, maybe it is too hot.

but im fairly new to re-loading.

Were all the cases fired like that or just the odd one?

That's only one mate, I need to ladder higher to get better signs an know this combos limits
An will see when I fire the other 5 loaded to this charge again an check speed to the 2 ladders I have done as well

but is it getting a better MOA as you go higher?
