VERY NICE, your timber is much like that on my Dakota .338WM, which is now in a fine Micky-"Hill Country" synthetic, but, spent the first 15 years I owned it in it's original wooden stock...and shoots so much better than I now can hold that it is kinda embarrassing!
Can't help with loads, as I have only loaded 285 Speer GS, 300 SGKs, 300 HBTs and, best by far for me, 300 NPs. I use H-4350 as I found a deal on 10 lbs of it, but, my highest velocities were with W-760 and I only load 300s.
I got an average of 2625-2650, max. Nossie book with this powder and VERY fine groups from three P-64 Mod. 70s, I had, my old Browning Safari and the Ruger MKII I bought in Oct. 1990. All shot well and "fast" with W-760, the above figures came from the 25" bbl. of my first P-64.
So, might be worth a try in your lovely rifle.
