My 200 LRX are in the mail from Midway.
The challenge is seating depth. That will tell you your charge weight.
Alliant lists a load for a lead based 200grn bullet using Reloader 25. I believe the rule is take 10% off the min lead load and use that as a max load for copper and start at 90%.
But seriously, as we now know. At least one manufacturer is using QuickLoad to give answers. Combined with the data from the Hodgdpn and other manufacturers data you have a reasonable load.
I could give you what I will try but instead recommend that you purchase QuickLoad and a Hornady LnL gauge or other method to check max COAL.
If you know your COAL, know what powder you want to use, can't afford QuickLoad (as in it's bullets or QL) then PM me.
There is also Ammoguide and Reloadersnest but they only have lead loads.
