Alright folks, here's the results!
It fires just fine but it does not cycle the action. Most of the time I'd get stovepipes but if it was ever able to get a casing out of the action, the bolt did not go back far enough to pick up the second round.
All of this was expected and fixable with reducing the weight of the bolt.
So far, so good!
I have attached some pictures of the casings. I was concerned I'd see some pressure signs due to the bullet being a slightly larger diameter but I'm not seeing anything that concerns me greatly.

I do see some ringing of the cases about a quarter inch up from the head. I'm not concerned about this since I won't be reloading anyway but it was unexpected.
Diameter wise, the 38 Super is larger than the .351 Winchester. I wouldn't have expected there to be room for this to happen.
I have purchased a 15 round 1911 38 Super magazine for the next steps. Total project cost = $185 so far.
Any thoughts/comments?
