Hello. First, I have never owned a Delta Elite or any 10mm; I'm just not a fan of the round. I will relate what I've observed with a couple of friends who own and shoot Delta Elites.
First, they both love the guns. The time or two that I've shot them, they were reliable and accurate. I was shooting the full-house Norma loads and recoil was sharper than with .45ACP.
It's my understanding that certain factory loads in 10mm are no hotter than .40 S&W and I'd guess that you could shoot these practically forever as the pressure would likely be lower, or at least not spike up as fast as with the forty.
If you felt the need, you could use one of the full power loads for whatever.
The 1911 platform seems to be what's being used for such things as .38 Casull, and other semi-wildcat rounds like .45 Super so I reckon it'd likely handle 10mm. What I would do is determine the factory-rated recoil spring and use one a couple of pounds stronger if the gun functioned OK to prevent battering and would likely use a shock buff as well.
If you handload, you might wind up loading something a bit faster than forty, but not as hot as the hotter 10mm loads such that you could do about everything with that one load and not have to worry about harming the pistol as your handload would be something less than a full-house load.
Best, and again, these are just opinions and assumptions as I do not and have never owned a 10mm. Hopefully someone here will be able to more precisely address your questions.
