I have been looking for some load data for this combo. I found vary little so i will post what i have came up with.
First off i have 2 barrels one is match chambered with a short throught. The other is standered with a much longer throught.
Now the same loads did not work in both.
The match barrel with a shorter COL
80gr IMR8133. Made 2620 fps
82gr. Made 2710
85gr. Made 2917
All shot fair with no pressure but i had a few key hole at 100 yds its a 8 twist same as the other barrel and it has never key holed so figer i have a barrel issue with that one.

Now the bareel with longer COL
Volocity was about the same even with bullet seated out but the 85 gr load that had no pressure issue in the match chamber did in the long chamber it had flatened the primer had bolt face marks on it but still extracted fine.
Morale of that is a starting point for some loading but what workes well for one dose not mean it will work well for all or even another.
Load with care, shoot safe, have fun.
