<<<<--------- as you can probably tell that is my pick for my rifle

I use it for my all arounder for deer, elk and moose with no problems. While long shot are a good possibility for me, I haven't needed them for a few years but was one of the reasons I picked the 7 Rem Mag. Whitetail I prefer 150 gr Ballistic tip style bullets, but anything from 140-165 will work fine. On bigger stuff 140-175 solid constructed bullet will work well out of the 7 rem mag, just find the right bullet and drive her home.
Optics depends on the funds but I would suggest a 3x9 or 3.5 x 10 should suffice (maybe a 4-12) I prefer 44-50 mm objectives but anything 40-50 should work well. If your looking to save a bit in funds but a decent scope in optics the Bushnell Elites are a darn good piece of glass that won't break the bank. Lots of good options, to many to list from mid to high end, your best suited to either narrow it down or at least give the members an idea how much cash you have banked for glass.
