I've used 150gr Ballistic Tips on Blacktail deer, and 180gr Ballistic tips on Mulies. I've also used 220gr Nosler Partitions, and that is my favorite load. Mind you, I often was hunting Elk or Moose, and deer was an added bonus. If I were chasing only deer, I'd stick with 180gr Accubonds. They fly flat, hit hard (I've used them in my 7mm RM on deer) and buck the wind well. They are also economical, so you can practice lots. I used RL22 when loading 180gr Ballistic Tips.
edit: Scope will depend on how much money you want to spend. On the low end I would say a Weaver K4 or K6 would do just fine. They can be had for under $200 and are a very good value. On the high end I like Schmidt & Bender scopes, but they are very pricey! There are lots of good choices in between. What terrain will you be hunting in?
