Well I am building a .460 Rowland using an NP-44. I heard from a trusted source that the Norinco 1911s hold up well to the high-pressure, high-performance round. Just curious what max loads CGNers are using and if you have any advice towards the cartridge any information is appreciated!

Brownells used to sell the barrels too, might still be able to get them from them. Mine is built on a Norinco as well, one of the non marked ones Canada ammo brought in a few years ago. I've only tried Higdon Longshot in it, with 200 and 230 grain bullets. Haven't shot it much, but I think I was getting around 1300-1350 fps, but the primers didn't look very good with those kind of pressures. Definitely backed off a bit from there. The 460 Rowland website had load data that I used, and that's where I ordered my barrel and brass from. Rusty wood, a site sponsor here, also sells the brass.

You can save time and money and just load a strong pistol like the Norinco to 460 Rowland levels using Starline 45 Super brass and published 460 Rowland loads. The 460 Rowland has the same OAL as the 45 ACP, but the cartridge is lengthened not for strength, but to prevent it from being loaded in a non Rowland gun. People have been loading strong pistols ot these levels for many years with brass being the limiting factor. 45 ACP brass is too weak, and until we saw 45 Super brass arrive, people modified 308 brass to make "45-08". Search on "45-08" and "460 Rowland" and you'll see several useful threads.

P.S. I like using 11.0 grs of Longshot with a 230 gr FMJ for ~1300 fps. No brake on my gun, but a stronger recoil spring was needed. The brass gets flung very far, so a deflector or catch is a good idea. The novelty will wear off quickly, like owning a 300 RUM, all the more reason to do it the quick, easy and inexpensive way.

I see what you mean by using 45 Super brass.
HOWEVER - It is the same length as 45ACP. Murphy would load some in my regular 45 pistol. Not good.
45 Super brass and 460 Rowland are both readily available and about the same price, so I will use 460 to prevent a Murphy.
That's a lot of money (~$400) to spend to prevent something that easily prevented, e.g. only load what you'll shoot up in one session, colour or mark brass, or just be careful and segregate loaded ammo. I have milsurps in 6.5X55 that shouldn't shoot the same ammo as my commercial rifle and I have no difficulty keeping that straight, and many people have 45-70's of various strengths..............
If someone must use 460 Rowland brass, running a 12 mm (15/32" might work) Chucking Reamer into the chamber a few thou would be the most inexpensive path to follow, but then the barrel is no longer usable for 45 ACP.

I have a kit on order from A z t e c h Armory. Brass has been a struggle so far. I have plans to buy a bunch of .45 Super brass as well. Most of my shooting will be with the super. I am actually selling my only ACP so mixing ammo won't be an issue.
The Rowland shoots regular 45ACP ammo, so long as it is not wimpy. The round strips from the mag, under the extractor, which holds in onto the bolt face.
.45 ACP, +p and Super will all shoot from the Rowland kit. Likely need to switch to a lighter spring for ACP and +p but it does work. Since Rowland brass is only slightly more than Super I am back to just loading Rowland for my gun... Power Pistol and AA powder of any kind has always been a struggle to find for me so I am stuck with Longshot which I have a great deal of. A measly 1300+fps with a 230grn bullet will have to do I suppose. I'm looking forward to this project.
I am presently working up loads for a precision rifle in 45 acp/super.
It is in the savage 112-J target rifle. One pile of fun!!!
230’s going 1425-1450 with Longshot and another powder. Silly rifle shoots 1-1/4 MOA or less at 100. Often times well under! Now to get to a gopher field!
Love the 45ACP cartridge! Fun all around!

I'm bumping my old thread to share some info...
At some point Hornady changed the profile of their 230grn XTP. This new profile has a much longer cavity, that means you need to seat deeper than the shoulder in order to fit it in the mag. I now have a lot of bullets I don't have much use for.
All my load development was done with the old bullet, but I only had one box. I guess I will try loading up a bunch of Super ammo... The XTP just doesn't do well at ACP velocity. That can be also said for most .45 JHPs though.
