Brass sticking in chamber.

[Oh Mah]

sorry, no i have never got into the annealing as of yet.

The brass needs replaced. Look for all signs of pressure on the new brass. Fired way over 20K of .300 Win Mag. Not a typo “Way over 20K”. It has been my favorite chambering since 1986. I have shot out barrels chambered in .300 Win by Krieger, Pac-Nor, Schnieder, Mike Rock, Obermeyer and several factory Rem700 Sendero’s. A factory Sendero if it isn’t overheated and abused will easily go over 3K. I started shooting a 25-.284 about the same time. The .300 Win Mag barrels way out lasted the 25-.284 barrels.

as it came out of the chamber.yes i have headspace comparitor,no cratering.


ok i will scrap the brass and get some new. 

I really hope the primer was still in there when it came out of the chamber, otherwise I think we found your problem!

81.0gr of H1000 with a Nosler E-Tip is a pretty hot load. The solid copper E-Tips hit pressure a lot sooner than cup and core bullets because of their extra length the different material. Do you have a velocity for that load?

When I hunt I shove a hand full of .300 Win Mag cartridges down the front of my briefs. It’s extremly liberarating in a “Right wing” sort of way!

[Oh Mah]

when i do get into the annealing its only the tip right?Is it different with belted brass?

[Oh Mah]

@Biggerhammer--How can you tell if your extractor is going?

[Bofire]

check your head space.

[Biggerhammer]

I’m not going to read through the whole thread.

Is it a Rem700?

[Oh Mah]

yes

[Oh Mah]

check your head space.
Carl

do you mean with a go no go gauge?

[Bofire]

yes, with all the ideas you have been given, it seems like everything is checked except the rifle.

If brass is sticking. It’s not a extractor problem. It’s a brass issue. With a factory Rem700 bolt/extractor. You will destroy it with sticky cases. I have replaced several Rem700 extractors on Factory Sendero’s when I pushed them too hard. All my customs have Sako or Sako style extractors.

With the Sako extractors. A guy can’t incinerate a primer, have a ton of smoke roll out of the bolt and it will still eject the cartridge with a ample amount of force. The same load  will destroy a factory Rem700 extractor.
