I own three 7mm-08s in the following guns:
1. Remington BDL SS DM
2. Sako 75 SS
3. Tikka WH SS
I have not yet shot the Tikka WH SS.
In my Sako, for some reason I cannot cycle Federal Premium 140 Nosler Partitions. In fact, I have the hardest time just trying to close the bolt. This ammo cycles fine in the Remington, which shoots it MOA or better.
As for the Hornady LM, there are two bullets available, the SP (I think BT too), and the SST. Both my Remington and Sako shoot both (if I remember correctly) MOA or better, but I do know that they both shoot the LM SP better than the SST - 3/4" MOA or better, and sometimes half-inch groups if I do my part.
