I will admit I don't have a lot of first hand experience with the 7 mag and factory loads but I am an experienced re-loader. For deer and antelope many people tend to use the lighter, soft point bullets. This is fine, but I would recommend you stick to a bullet with controlled expansion. the velocities of the 7 mag can do a lot of unneccessary tissue damage with bullets that are not bonded or have a thick jacket. I hear a lot of good things about the hornady line of ammo and personally like their interbond and interlock bullets. You can also find factory ammo with nosler accubond or barnes bullets. In your case, probably the most important thing is accuracy and you may have to try a couple brands or bullet weights to find what shoots best. Enjoy the shooting and good luck in pursuit of the goats.
I'd go with the Winchester 150 ballistic silver tip. I've used 150 grain nosler ballistic tip hand loads and these are almost the same thing.

I've used the 150 gr Nosler Ballistic Tips on deer and pronghorns with great success and reasonable meat damage when shots are properly placed. Used the 150 gr Swift Sirocco on elk successfully too...nearly identical drop chart. Just bought a Savage Long Range Hunter in 7mm so will see what it likes best. Will try the 168 Berger as an all around load.
“You don’t need that” my loving wife stated flatly. Hovering near her, sporting goods catalog in hand, I tried to counter “But look Honey, it holds 2150 cubic inches of gear”, as I tried to give her my best loving look. “Nope, you do not need to carry more gear – you have several packs already… if one of them is not big enough, take two” she stated and then fell back to attacking her Sudoku puzzle. Sulking, I moved back to my side of the bed and continued thumbing through my...
