Do you have some brass that chambers to compare?
Usually brass sticking in the chamber is a sign of pressure, what is your load?

How much were you bumping the shoulders? 5-6 firings is pretty quick
Post by: BULLBLASTER on May 01, 2018, 07:07:33 PM
Bend a paper clip with a short 90 at the end and straighten the rest of the clip. Run the clip to the shine and you should feel a little valley there. Brass is thinning and will get a separation there and a stuck remainder of the case. Discard case, usually caused by over working a case.Seems a bit close to the case head to be separation, but possible.

Looks more like just where the sizing die ends

Is it time to buy new brass?Is my load to hot?only recently started this load i think brass has fired this load 2 times now.the load is
81 grain h 1000 180 grain nosler BT.3.340 coal.

No need to get butt hurt about it.I bring the die down touch off(cam like)on the case holder and run.

Post by: yorketransport on May 01, 2018, 07:25:10 PM
Do you anneal the cases? They could just be getting work hardened and don't have as much "spring" to them any more.

I really hope the primer was still in there when it came out of the chamber, otherwise I think we found your problem! :chuckle:
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?
Post by: yorketransport on May 01, 2018, 07:50:49 PM
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.
Show off......... :chuckle:

you got me here lol.i resized it about 6 times to get clear interference marks and the primer was pushed out. :chuckle: in my book under my notes i have average of 3108 fps. 10 shotsas it came out of the chamber.yes i have headspace comparitor,no cratering.

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!

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.

Brass looks like it needs annealed. How much are you bumping shoulder - .002 ?Can i anneal the entire brass?

Annealing is designed to soften the brass where it gets work hardened. Elsewhere, the brass needs to remain hard or you risk catastrophic case failure.

So i went and checked and between the 4 diff. case holders for the .300 are diff. thicknesses depending on the brand.
Moral of story put your case holder in the die box and store it there when you get the right one for your rifle. :tup: We are machinist and he has ground his to the exact .002 under his rifles head space.Always learning.
Thanks for all replies, without them i would not have come to this.If i was checking with my head space gauge i would have caught the problem before also.

Need re size to 2.268 :tup:
Post by: BULLBLASTER on May 03, 2018, 06:10:30 PM
I anneal all of mine every firing. But every couple firings is probably sufficient
Post by: Biggerhammer on May 03, 2018, 09:21:52 PM
Neck and shoulder should be heated to 750 ish degrees. Putting them in water isn’t necessary.
Exactly, the water thing is just time consuming. Once you load for your rifle enough, you can feel the neck tension lesson up. That’s when you need to aneal. With my .300’s and my loads, I aneal about every three firings. When I do, I aneal all of the brass at the same time.

Put drill on slow, brass in socket, center shoulder on flame 2" out, angle brass so flame goes along shoulder angle. 5-6 seconds in flame, gently drop on crunched up aluminum foil to avoid denting or dump in pan of water.
I use metronome app to count out exact seconds.
Test your time - turn off all lights, count how long it takes for brass to just barely turn red at all - this is max time.
You will see brass turn kind of shiny from tip to 1/2" below shoulder. This is when you stop.
Try it ! You can test with a punch to see your progress.

Isn’t absolutely necessary but does a consistent job and is easy to run. I just fill it up and let it go.
I don’t have a picture of the machine on my phone but this picture is some 6mm creedmoor rounds I annealer and necked down from 6.5 next to some 243.

I have a giraud tool machine.they don’t appear to be very consistent. Colors run down at different lengths. My hand annealed brass is more consistent than that. I would expect machine annealed brass to all look identical.

I think what you are seeing is just the angle of the pic and the cartridges not being lined up very evenly. For instance the one on the far left is back slightly making it look like it's a different sized case all together. I promise you every single piece that comes out of that annealer is perfectly identical. I've run thousands of pieces of my brass through it and it's on point every time.I have a giraud tool machine.they don’t appear to be very consistent. Colors run down at different lengths.

Could just be the angle of the pic. I’m happy I have the experience to not need the machines and For the price of those things I’ll stick with my torch and fingers and put the money in components instead. Pretty nice of Chris to share his toys.has nothing to do with experience and everything to do with ease of use. I did it by hand for 15 years and could do it by hand for the next 15 but machine is easier no if ands or buts about it. And yes chris is a generous friend :tup:
