I’m not grasping what that would do.
Wouldn’t that keep the extractor from engaging as well?

No, it will add a few thousandths to case length. If it closes you have excessive head space.

3 pieces of blue painters tape cut with a razor around the case head. Four and it was squishy but could close with the FA
At no time did the extractor pull the round back out. Each time I had to tilt the barrel up and let it drop out.

Your case is .005" short, not an issue. IMO.The 450 rim is larger in diamter and thicker then a 458.
The Hornady factory ammo may be over pressure?
Compare the fired case diameters to SAAMI.

Yikes.
Do you have calipers? What do 4 strips of painters tape measure out to?

I do but I’ve done left the gun dungeon. I’ll go back down in a few when the kids go to bed.

curiosity got the best of me. 4 pieces of “unsquished” tape came to .061.
The “belt” on the stuck case came to...

High pressure causes brass to stick in the chamber and puts "belts" on brass.
Maybe try some Rem or Win. ?

I think with the failure of the extractor to grab the rim, I’ll send the upper back.

Yeah I was fully expecting that to happen when trying to get it unstuck. With my luck I’m really surprised it didn’t happen. Had my compressed air can ready to freeze the case if it did.

Hornady has a knack for making straightwalled pistol brass shorter than spec. Check specs against your cases. I suspect they may scrimp on brass for other things as well. It’s one of the reasons I quit buying from big red.

The bolt (extractor) is from Midwayusa?

The extractor position could be set back to deep in the bolt. There is a photo of that also.

Sounds like the really screwed the pooch on the chamber. .061" headspace would cause a bottleneck case to blow the case head.
I'd definitely be seeking replacement or refund.

Chamber maximum 1.710"
Case trim length minimum 1.690"
Different bolt= different headspace.

I think you are going to have to reload for that rifle. Factory ammunition is way too hot for your chamber and barrel. And that is the bottom line, not some bogey man about case length or cartridge case protrusion. Whenever a factory new case looks like a belted magnum, after firing, that is a pressure problem.
The belt location reflects just how much of the case head sticks out of the chamber. If the case head did not protrude, you would have to use a ramrod to extract cases, because there would not be enough room for an extractor to grip the rim. You are lucky Stoner designed a particularly strong locking mechanism, for its weight, and that the case brass was good. Things would have ended up a lot worse had a case head blown.
I would call Hornady and fuss at them. Factory ammunition should not be causing these problems. Maybe you can convince them to send you 1000 primed cases, which you could then reload, with a reduced charge.

Slamfire,
You must have a collection of the most awful and alarming pictures of mayhem and kabooms of any THR poster on firearms and brass. Either you lead a very exciting life testing stuff to destruction or you have mad internet researching skillz.

I think 243WinXB has more.
I just collect them because I can use them to illustrate a point.I try not to create any of my own Kabooms!
