It can have meaning when you check the diameter to the proof if the difference is great it could mean thin walls or if a type of gun was traditionally 729 bores and it's now 740 might indicate wall thickness problems.so bore diameter might be important

Most of the light game guns, and most vintage doubles, from various internet dealers I observe have wall thickness no where near .040, with most advertised as under .030. Many are under .025 with reproofed 2.75” chambers. No thank you.

So 2.5 on a side is the deal breaker?

Depends on where on the barrel, but generally .025” barrel walls is a deal breaker for me.

Because you are worried about denting/repairing or because you think there’s a potential for a random burst at that thickness?

Most light game guns were made with thin tubes, .025" or less when new. You really need to look at the original bore diameter and barrel wall to understand what you have and how safe it is. I have no issues with a gun that is thin out towards the muzzles as long as it has plenty of wall thickness in the first 9" or so and it's price reflects the barrel condition.

And never buy a gun from someone who won't let you have time or shipped to a double gunsmith who has the tools and knowledge to do a proper evaluation or avoid the hassel and go to a gun dealer with tools and knowledge and stands behind his product .there is much more to a proper gun evaluation then 30 90 ?

My first concern with vintage guns is safety. I’m with SKB on this in regards to location of the thin spot of the barrel. If it’s .025 towards the muzzle, no problem. If it’s .025” at the end of the forend where my hand is, no go. More dealers are disclosing the MBT, but they don’t say where on the barrel the thin spot is. That’s what you ask when you call them up. These tolerances are simply my personal policy, YMMV.
