case head seperation help

[scratchmark]

well i guess im offîcially a handloader. today i opened my 25-06 after firing and the only thing ejeted was the bottom 3/8 of the case. any best practices on removing the rest from the chamber?

Broken case remover or sometimes a tap of the right size will snag it.

You might try cleaning it real well and filling the stuck case with cerrosafe, let cool, then knock it out.

Thanks, Dinny

A lot of times a tight fitting barrel brush or mop will remove it.

My first try would be a good soak with CLP and 10 minutes in the oven at 175 degrees followed by 1/2 hour in the fridge or freezer if it will fit and then running an O ringed jag - one of those tight fit to the bore - down from the muzzle hard (with a patch to help catch the case mouth) That should do it.

tight bronze brush on a quality rod

Please dont try running a tap into it.......the tapping action to snag the brass puts more outward pressure on it and any tweak out of line or cut to deep and you have just scored the chamber walls.
Ive found these results in several rifles through my shop, and its always a disappointment  .
The best first thing is to run a good, new stiff bristle oversize jag up into it. The new tips dig in a bit and the bristles dont like to reverse themselves. Very often that pops the case loose. If not, lets talk about it some more.

If your 270 brass is all the same vintage as the broken piece you might want to buy some new brass.   Could also be a headspace and/or hot load issue as well.

thanks for all the great ideas. BB, ive otten alot of brass from different sources and some is resized 270. so pinpointing a vintage issue would be tough. barrel fits tight and headspacing seems to be o but the did open upon fired on this round only.

well the cleaning brush worked perfectly, just popped it right out. looked at the other brass that was shot and all looks well. So , im wondering if the gun popping open created a temporary headspace issue resulting in seperation. this was the only shot where that happened and cant say whether i checked before hand or not.

You may want to sit under good light, and with a magnifier if possible, to inspect all your brass at the point of separation. You might detect some that are looking a bit iffy. For instance, a substantial shiny ring indicating overstretching and resizing right there, etc. An old 'inner inspection' trick is to bend a feeler tab on a paper clip to reach down in there to feel for that thinned spot. Some say to toss any that have it. Ive saved some with a bit for low velo/low pressure loads, though YMMV.

SM,
 
Is all your 270 brass the same HS?  270W is a fairly high pressure cartridge and if you are mixing HS brass you might have had a high pressure situation.   Also, if you have a pop open from an overpressure event I would check the lockup of your gun as you might be in the market for a shim.  Hopefully, your problem is just from worn out brass and Mr. Crank has provided the help for inspection of your cases.

good deal.
glad that came out so easily.
the rest of the problem is
likely just as easily fixed.
good luck

I tried that and it worked good, then I tried a large Safety Pin stretched open, and 1/8" of the tip bent 90*.  works really good for me.

the point really lets you feel any anomalies. 

I had a large bunch of 303Brit, and 7x65R to go through, and it was a snap!

A guy does need to have 'feeling' left in his fingers, through........... . When doing things like this I like to close my eyes, it seems to help me visualize.
