Something to note and keep well up in the front of your thoughts is that if there -is- a problem with alloy or the state of hardness, and the gun hasn't been used much or enough to develop such shortcomings, they won't show up as problems in x-ray or dye tests.
That and a test isn't a guarantee that a gun won't blow to bits under an overcharge or pressure spike.
All a test like this will do is show if there's signs of decay or damage that would show up in an x-ray or dye test.
That's it.

And something I'd like to note is a huge swelling enthusiasm to shoot my bore rifle and my 450 since this afternoon.
I sold a french double tonight to fund a strain guage pressure transducer kit, I'll be ordering that tomorrow and marrying it to one of the laptops out in the shop. Hopefully that will come together as soon as the woodwork is done too. Even if the pressure guage system isn't calibrated, they tend to be rather consistent, and can be used in conjunction with a chronograph to read and calculate for such things as muzzle timing and massaging the pressure curve.
I have some homework to do tomorrow morning before I get out to do chrono work with one of my revolvers.
fun fun fun...

So, to the point.
The shop I used for my testing today is

QC Services

Thier phone number is in the book and I'll leave it off this posting to keep the evil spybots from dragging it into a call list.
Find that on the web.

The guys cleared a pallet of alloy steel aircraft ejection seat gas manifolds out of the X-ray machine to make way for my barrels, they do quite a bit of aerospace work, no room for a screw-up with that part...

I had asked them if I could pass thier information on and if they would be interested in looking at other guns, they noted they'd be happy to take more of this kind of work.
No stinking liberals there. Not at all.
