Hardest part was learning how to properly
headspace a barrel. Do it wrong and possible kaboom.

More like a failure to go into battery, causing a failure to fire or
failure to extract, causing a double feed jam.

He's talking about the AR-15 he "built", and there's really nothing to headspace on one. If the barrel and receiver are properly machined to spec, it has the proper headspace built into the design. When it becomes important is when you are fitting a more traditional barrel and receiver together, and are doing the machining yourself. Let's say you have a Mauser 98 action, and you're building a 30-06 with a Shaw barrel. Then you have to check and machine in the correct headspace, and even then it's not hard to do.

Another fabricated Fat Harry story?

Barrels in sporting rifles don't headspace themselves automatically, and
it is worth taking a few minutes to check it. If JackOff wants to take
the chance of a kaboom, it is fine with me.

You still have not said where the kaboom comes from. If the headspace
is too large the extractor might not grab the rim, causing a jam or
the firing pin might not hit the primer, causing a misfire, worst case
a hang fire but they are very rare with modern primers.
If the headspace is too small the bolt won't close. No boom at all
there. A bolt action usually will not shoot until the bolt is seated
and a SA has a disconnector.

I suppose all you gun fanciers are waiting for Fat Harry's learned
response.

Ask your limited experience buddies...

What happens when excessive headspace makes the casing split, the gas in
the chamber is not sealed, and the gas is vented into the breech.

Define excessive, oh learned one.

Excessive..."too much." Got it, imbecile?

It's no surprise that you can't express the acceptible variables
in terms that are meaningful to your audience. You need to do
more googleing and get more insight into the subject you pretend
to know.
