I found good accuracy but pedestrian velocity with Reloader 17 using 140 Partitions out of a Tikka T3. I switched to Big Game and used Winchester Large Rifle Magnum primers and got slightly better accuracy and significantly better velocity.
I use Big Game exclusively in my 7mm-08s as well as a...
My new load is 150 ELDX at really close to 2800 fps. My nephew killed his first bull this year with this load at 407 yards. 5x6 bull. I killed a 4x4 buck with this load, 30 foot recovery.
Run the figures, it's a surprisingly persuasive killer.

FYI I'm a 7mm-08 homer. I've killed deer, elk, and antelope using 140 grain bullets started at 2877 fps using Big Game powder and Winchester Large Rifle Magnum primers.
Plug those figures into a ballistics program and evaluate the real-world difference 150 fps makes. Zero.

I do it the same way. I color a bullet with a black Sharpie and seat the bullet on an empty unprimed case. I seat gradually shorter until the marks left by the lands are square. That's my max OAL.

Here's the results:
First up, T3 Superlite, 1-8"
25.0 grains, average 2824, high 2827, low 2823, ES 4
25.5 grains, average 2908, high 2929, low 2891, ES 38
26.0 grains, average 2924, high 2927, low 2920, ES 7
All brass looked great, no pressure signs.
Next, T3, 1-10"
25.0 grains, average...
Hodgdon lists 26 grains as max for a 70 grain SPR SP. I loaded 6 each (3 per rifle) at 25, 25.5, and 26 grains, 2.281". I'll shoot over the chrony tomorrow.

I'm looking for some information with loading Nosler's 70 gr RDF bullet in a 1-8" Tikka .223 Superlite. I'd like to shoot out to 700 yards or so and the published BC is .416, which interests me greatly. I loaded 24.5 gr of TAC at various seating depths but got inconsistent results.
I have...
Ballistic coefficient isn't a significant factor until you get out there a ways, more like 600 yards and up.
160 NAB is a great choice. I went with Reloader 26 and 162 ELDX, but I shoot at 600 regularly.
P
Don't forget the 162 ELDX, I'm using Reloader 26 for right at 3100 fps. One buck, one shot, DRT. A big 6x6 bull, one shot, DRT. My brother killed a big cow elk, one shot DRT. No long shots this year but we typically shoot 450 to 550 yards.
