Ok, I picked up some 525gr bullets for the upcoming arrival of my new CZ in .505 Gibbs and was wondering if anyone can suggest a starting load? Was thinking of keeping it around 2100-2200fps. Maybe H4831?

That is a cavernous case. You'll definitely burn the powder with that big boy.
It looks as if several powders will give you better case fill than does H4831.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 38000 psi, or 262 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
