I bought some accidently (thinking they were 45-90) Can I use this to make 11mm mauser cases? or am I better off trying to sell/swap them? Anyone using this brass?

I'm not using it, but I think you would be better off selling it to one of the BPCR shooters and finding something closer to the size you need.
I could be wrong, I don't have my books here but I don't think the dimensions (case head dia. and rim dia. and thickness) are even close on those two cartridges.

The rim & case head near rim are close, but it tapers after that very gradually
The .43 Mauser case measure 0.510" at the base. The 40-90 SBN measures 0.500" at the base, close, but still bulges the case if used.
Some shooters have been making .43 Mauser brass from either 7mm Mag or 300 Win Mag brass.
Machine off the belt, and headspace off of the shoulder rather than the rim.
You can adjust the sizing die until you obtain the desired results by incrementally pushing the shoulder back until the bolt closes.
There's a couple of threads posted here on CB, you might want to use the search function and look them up.

CCC is the old Connecticut Cartridge Company. They did at one time make a lot of unavailable brass cases. But sometime during the Vietnam War they stopped with brass for older guns and started making cases for the Gov't. Seem to remember them getting a contract for 30 M1 carbine brass. Would probably have to anneal that old brass before using it. Frank
samari46 has it. CCC Connecticut Cartridge Company, I had their 433 Egyptian brass for a Remington Rolling Block, delivered by the US Post Office, like the 433 Egyptian cartridges loaded with black powder and lead bullets ordered through the mail (no Internet until late 1980's). Brass was extremely heavy through the head and lower case walls. They did get a 30 Carbine contract when Vietnam heated-up, early to mid-sixties for their specialty brass. Case head was unusual, kind of like some of the turned brass cases.
GONRA's memory (?) recalls that CCC Connecticut Cartridge Company
odd caliber brass was from initial lathe turn fabrication.
Read that this requires 2X usual drawn case wall thickness.
Check it out...
BTW I was able to fire form 2 of these cases to 11mm Mauser using 700X & cream of wheat (no annealing done)
