Are there any local smiths who can bore a 40 S&W out to 10mm? Thought I'd check here first before sending my 405 and 16-40 out.
Going from 40 to 10

have you taken into consideration the additional pressure of the 10mm vs the .40?
I honestly thought when I read the title of this thread it was going to be on the maturity of the election protesters. I really did. 
As to the original question, might be too far away but Jack Mortimer in Havre De Grace is good. http://www.jacksgunworks.com/

37.5 kpsi versus 35 kpsi. Not that big a difference really.
The difference between 40 S&W and 10mm is really just OAL and consquently the size of the pistols chambered for it (9mm v 45 ACP size). Load a 40 S&W to 10mm OAL, and it'll do everything the 10 will with brass that's much more readily available. In theory, 40 S&W brass is stronger than 10 due to the small primer pocket.
I am getting ready to section an assortment of 10mm, 40, and 357 SIG cases to do a case wall thickness comparison.
I would also look in to getting a conversion barrel rather than reaming the 40 barrel.

Barsto uses the same barrel for their 40 as they do for their 10. Lost of folks have done this with their Paras. The revolver is long enough, and it's a heavy 5-shot revolver on a K-frame sized frame. I'm not really worried, I'm not going to be putting a steady diet of nuclear loads in a 2" steel framed revolver.

But that would be more of a Water Cooler post
I'll call Jack next year and see if he has the reamer. See my first comment on this post. Barsto seems to have stopped selling their 10mm conversion barrels

in the para is there enough room(dimension wise) in the mag for the 10mm round?

With the cylinder, I have almost as much travel as a Glock 29. And it gives me options that just the 40 doesn't.
The whole idea sounds like a good reason just to buy another gun
I'd love a 610, but have you priced one lately?
Wish I still had mine. Of course, I'm looking at the Kriss Vector 10mm carbine 
The frame is the same as the 45 ACP version, and yes, I loaded up a full mag with 10mm ammunition and it fits

Now that you mention it

Someone had one on Virginia Gun Trader for the same price. It sold before I saw the ad
