If elk is on the menu allow me to offer some advice. It’s worth exactly what you’re paying for it, but it’s tough to argue with experience.
Buy a box each of 140 grain AccuBonds and Partitions.
Find some Big Game, work up to 47.5 grains. Use a magnum primers. Try for 2880 fps at the muzzle...
140 out of a 7mm-08 should be an AccuBond or a Partition.
If you want to try TTSX, drop down to 120. And they like a jump, probably farther than you think.
Nothing wrong with experimentation.

You’re right about the Tikka but wrong about the cartridge.
7mm-08.
Deer, elk, antelope, all have fallen quickly (surprisingly so, in the case of multiple bulls) to a single well-placed shot.

Big Game. Use a magnum primer. Work up to Nosler’s max, 47.5 grains. Expect 2890 fps from a 22” barrel.
I’ve used this combo on deer, elk, and antelope.

Shooters Pro Shop wants $30 per bag of 50 for seconds. This isn’t off factory firsts by much. Then add $13 to ship and you’re really close to parity.

It’s max, so work up.
R-P brass
150 eldx
46.2 grains Big Game
Winchester Large Rifle Magnum primer
Seating depth tests in 3 Tikkas found screaming accuracy at 2.156” and 2.183” measured using a comparator, from the ogive.
2790 fps, no pressure signs. Deer and elk.

It’s my understanding that Nosler doesn’t make a bullet that closely replicates another bullet’s performance in the same weight. Same reason they don’t make a 7mm 120 grain AccuBond, the existing 120 BT provides nearly identical performance.
My brother and I use R26 with 162 eldx in our Tikka 7mm Rem Mags with great success. Deer and elk die right freaking now. I actually switched from the 160 AB to the 162 eldx. I’m right at 3k FPS.
We also use the 150 eldx in our 7mm-08s at 2790 fps for deer when we want to avoid a kick...

Based on this article I tried Hunter powder. 59 grains under a 180 Partition was outstanding, with velocity close to 2850 from my Tikka. This load has put elk in the freezer for me. I named the load Hammer.
If your brother wants the exact...
52 grains and a 162 eldx got me bright, shiny ejector marks and 2730 FPS from my Tikka. Easy bolt lift, though.
I get 2790 with the 150 eldx using 46.2 grains of Big Game. Doing the math, there’s very little difference until I get past 700 yards, which is waaaaay beyond my limit.

Big Game. Get some and use a magnum primer. I get 2890 FPS with 140 Partitions and 2870 with 140 AccuBonds. Precision I won’t post for fear of being called a liar.
