Manners eh series and proof barrels?

Tom told me the biggest Proof they'd do in the EH6 (or A) is the Sendero Light contour, like xtrem htr16 said. After seeing how much 'meat' was left on the sides, I don't believe I'd try a Sendero or bigger in it.....
 
EH6 will not fit a proof Scendaro contour, it will also be too thin to inlet any more once you receive it. The EH6-A will fit a scendaro contour. Don’t ask me why the A fits and the non adjustable doesn’t it just how manners explained it to me. I can’t speak for the other stocks or the scendaro light.

I have an EH1 ordered for a proof Sendero 300 wm build. On the EH1, manners called the barrel contour a proof medium, they said that told them it was for the proof Sendero profile.

EH6A was specifically developed for "Proof medium":

It looks like the proof is in the pudding in the above pictures but just thought I'd ask if anyone else can confirm that an EH6A can support a Proof Sendero contour (not Lite)? Manners just told me it won't over email but if it can be opened up counter to that, I'm in. Feels off that I'd have to open it up even after spending Manners prices on their work though. It's also weird that they have a Proof contour EH6A in the ready to ship section but say it can't support it...
