This every time.Unsized fired case is going to stick.
Who are you replying to?I posted a photo a few posts ago of my ground down shellholder.
You might want to read the rest of this thread for information.
Why reinvent the wheel?
My new Labradar shows my Six5 is averaging 2895fps with an 85gr Sierra with 1.6cc of Leverevolution.
I didn't think it would be that high. The primers show no pressure signs.
There are some that think SIX8 or SIX5 is just a cool way of saying 6.8 or 6.5. I've seen several posts where guys have ordered SIX8 pmags and then get pissed when they don't fit their rifle.I was replying to B4llsD33P. I thought it might help if his die was a little short like mine was.
On another point: I searched for Six5 on 65Grendel.com and received many hits.
After reading a few posts it became evident they were not talking about this cartridge (Six5 / 6.5SPC) but the 6.5 Grendel.
Naming conventions may be set but it sure can be confusing.
Just did, and no change.As a test, take one of your fired cases of 1.380 and resize it bumping the shoulder back to 1.375 then lock the bolt back, drop the case in the chamber and release the bolt allowing the full force of the bolt carrier to chamber the case. Then take it out and measure the shoulder set back again.
try resizing a fired case to 1.378 and do the same...Just did, and no change.
There may be some melonite crystals growing in that chamber.May need to polish chamber with Iosso bore paste.
Right, kinda like these "melanite" crystalsThere may be some melonite crystals growing in that chamber.
Never heard of melanite before.Right, kinda like these "melanite" crystals

Did this, no change in size.try resizing a fired case to 1.378 and do the same...
So if a fired case measures 1.380 and a sized case measures 1.378 and chambers /extracts fine, then it sounds to me like you're good to goDid this, no change in size.
I made a mistake in the shot strings in the Labradar (LR) the last time I shot. I forgot I shot a string of factory 308 Win. These should be 2900fps and the LR reported an average of 2895fps.My new Labradar shows my Six5 is averaging 2895fps with an 85gr Sierra with 1.6cc of Leverevolution.
I didn't think it would be that high. The primers show no pressure signs.
No, that would be a neck tension issue. Use a smaller size bushing to get the neck tighter.would this explain the bullet jumping becoming jammed when the bolt slams shut?
