Is this my FL die or is it really headspace separation?

I asked this question before " Any sign to be alarmed? Headspace separation? ", but this is new rifle and I haven't seen anything like it, so I would like to ask your opinion on this, is this headspace separation I'm observing? The chamber on the rifle just been redone and this brass was only fired twice and last FL sized.

Kinda does look stretched but that could be a photo problem. Maybe get a paper clip, straighten it out and put a little crook on one end. Use it to feel around in the inside of the case near the base. Odds are you can feel a difference in the internal wall if the thing is getting ready to fail.

If I write with the marker over it I can feel bump, but that's outside. Previous chamber was very hard to turn and it was scratching brass like this:






with this new chamber I have no problem cycling bolt. By the way my FL size die made by Redding, its their bushing FL die and I only bump shoulders 0.001".

Just shot 40 of them, checked everyone inside with paper clip, nothing inside, it must be my Redding die, but I'm only sizing half of the neck and slightly bumping shoulders. Could be chamber differences, my chamber is 6 mm BR Norma and on Redding box states 6mm BR Remington, but I was buying "Redding Type S Bushing Full Length Sizer Die 6mm BR (Bench Rest)"...

I see nothing that looks like you're heading for a seperation. And, proper die justmemt would stop it anyway.

boomtube, what would be proper way? I can lower it, but that will bump more then I need in the shoulders, moving it up will not resize it.

Jinx, I don't know how much you are moving the shoulder upon F/L sizing but if you have to set the shoulder back very much you maybe should switch to neck sizing which will save your brass from an early demise. I had to go this route on a custom chambered 264Win. as I couldn't even touch the neck with the FL sizing die until the shoulder was pushed way down, and I can only assume that the chamber was very over-sized. And people wonder why I really don't like belted magnums, as they are headspaced on the stupid belt instead of the radius of the shoulder. You never know what you will end up with on a custom barrel/chambering with them.
