Wow, that is a lot more Weatherbys than me. I too have a 7Mag, . Killed a some axis and a few hogs with the 140 TSX. Shoots well for me too. That said, I have not bought factory ammo in a long time.
I used the 139gr Hornady factory load. It always killed well. I also had a near lifetime supply of factory 160gr Partitions. I ended up giving them to my father in law, who I sold a another 7mm weatherby to.
