I tested some loads in a couple of 7mm08 rifles I've been building over the last year or so.
Tested with my 140 gr Nosler partition loads using W760 powder and regular LR primers.
No signs of pressure issues yet.
Using Caldwell chrono
Shooting at 8000' elev may have helped getting these velocities
24" Krieger barrel, 3 shots, Velocity was 2909, 2928,2945 = 2927 avg
24" Lilja barrel, 3 shots, velocity was 2815, 2944, 2940 = 2899 avg
I get 2885 with 140 Partitions from a 22.4” Tikka so I think your numbers are accurate.
The only 7mm-08 I own is a tikka superlite but I think I remember reading that Tikkas commonly have slow barrels. Any truth to this that you're aware of?
I’ve heard this too but if Tikkas are slow, they’re not that slow. I figure 25, maybe 30 fps per inch.
My Tikka is fast, I get right at published velocities for 24in barrels with the factory barrel. Tight chamber or fast barrel, whatever. It's also very accurate. I've used two different cronos to test.
120 BTs and H4895 3080fps, this is the load I use, low recoil, kills elk and deer easily, just well balanced in a light rifle.
Big Game I've gotten 3160 with the 120 BT
Staball 6.5, 139gr SST, I've gotten 3035, 3011, 3015 with max 51gr... and 2989, 3002 with 50gr. In a light gun it really jumped/recoiled, primers a bit flat and ejector marks, bolt lift was fine. Overall I don't like the balance of rifle and load. Dropped down to 48gr and it averaged about 2880fps, much better to shoot.

51.5 gr Big Game with 120 BT got me 3126. Kinda snappy but not over pressure.
