Brass sticking in chamber.
« on: May 01, 2018, 06:39:35 PM »
Been reloading for a while now,Starting to have troubles with my .300 win mag.Brass goes in just fine but after firing sticks every shot.I ran this brass thru my fl die 5-6 times as is to see any tight spots.you see the clean brass ring toward the belt.is this a sign of pressure or a sign that it is hardened and springing over size?

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.

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

No need to get butt hurt about it.

How much were you bumping the shoulders? 5-6 firings is pretty quick
Kindly do not attempt to cloud the issue with too many facts.

Seems a bit close to the case head to be separation, but possible.
Looks more like just where the sizing die ends

I bring the die down touch off(cam like)on the case holder and run.

I only size until it chambers and that’s how my brass looks too, slight change in color/angle where the bottom of the die is. Tough bolt lift sounds like a case of overpressure though

That load doesn’t seem overly hot. Are there any ejector plunger marks on the case head? Primer flowing or cratering?

Do you have a headspace comparator?

Just scrap the brass; that looks like a good warning sign of case head separation if you keep shooting it.

Do you anneal the cases? They could just be getting work hardened and don't have as much "spring" to them any more.

:yeah:  I had this happen recently and 2 or 3 other cases were ready to separate. 300 WM cases seem to get stretched after several sizings and they get thin in that area.
