Larry is correct. Your case photo shows only the normal rub of an FL sizing die.

The "bright ring" that is the incepient indicator of a head seperaton occurs after firing, not after sizing.

None of that means you AREN'T getting excessive case stretching, only that what your photo shows isn't of that type.

Most, if not all, head seperations are the result of repeated excess shoulder set back when FL sizing, not high pressure or excess rifle headspace, as such.

Your chamber dimension looks a little big at the back. If you have good brass it will be like that the whole way around. If the brass is thin on one side it will bulge more on one side. I had a Savage 25-06 that was worse than that, I used to pitch the ones that bulged on one side and neck sized. Groups didn't seem to mind it.

It's already been covered but that's pretty much normal. My Glock rounds all look like that as do my rifle rounds. I don't load hot. Factory ammo is dang sure not hot.
