for a beginner shooter, i would say a 270 is a great choice. even if your shot placement isn't exactly on target (due to buck fever) it will still have enough force to take the deer down. 130-150 grain would suffice.
as for a scope, either a leupold or a bushnell will do fine. stay away from cheaper brands such as tasco. 3x9x40 will work great for most situations.
as for handloading, not worth the time and effort if you are only hunting 1 or 2 critters per year. as the others said, find a certain load your gun likes that groups well and practice lots with it. some swear by winchester accubonds, my gun likes federal premium.
as for the gun, tikka's are very nice. buy yours at wholesale sports, $620
