Thanks for the pictures.  Here are two views of the Bren Ten (The first original 10mm designed) barrel...



When it comes to support I also think about the brass casing design, I need to do a cross section of the different makes of brass to see if one brand is thinner than an other in the web area.

We can call that one Delta Medium-Lite

Look close Intercooler, it appears to be a lot, but actually it is less than the thickness of the extraction rim...

It just looks loose all around. Maybe some feeler gauges would really tell more of a tale.

I think the looks there are deceiving. I bet it will handle any hot stuff someone was brave enough to put through it.

I am not that brave.


edit:  To clarify, my fear is for a collectible gun like the Bren Ten, not for me.

Just eyeballing the pics, I can see why my Barstow barrell never had a smiley. I went through 2 Glock barrels due to  large smileys with factory ammo.

Bar-Sto and KKM seem to be consistently good.  Old style Lone Wolf are usually good, but then sometimes they varied (they seem to lack consistency, barrel to barrel).  I've seen differences in Storm Lake barrels, but never with less support than KKM and Bar-Sto.

In terms of chamber support I consider my Storm Lake barrel to be exceptional which was special ordered just a few months back when they could still be ordered factory direct.  Here's a pic of mine;




The most exceptional factory barrel in terms of chamber support that I've seen comes from Kimber as seen below;
