First off, welcome to the forums! Always great to introduce someone new to the sport! I took two people hunting for the first time this year and it was great to see them have a good time.
I have never personally fired a Tikka, but I have heard good things about them, and the .270 is a GREAT cartridge for white tails.
Well, deer hunting is not rocket science, but there are a few tricks to the trade. The biggest thing that will help your success is to scout out the area you are going to hunt first to try to determine movement patterns. Make sure that when you are out scouting, even well before hunting season, to descent yourself and your clothing, especially the bottom of your boots with a good descenting product. During deer season, carry a small bottle with you so that you can spray down your stand and touch up yourself (especially your boots) on your way out. Human scent can keep a mature buck out of an area for a long time. A deer's first line of defense is its nose, and you can not totally eliminate your scent so you have to play the wind and the thermals as well. I also like to carry a grunt call with me. Since you can't help but to make noise sometimes getting to your spot, you might as well try to sound more like a deer than a hunter.
Basically, do your research and pick a good spot, cover your scent, use good ammuntion in a rifle you have practiced with sufficiently, be patient, and you should be eating jerky and summer sausage in no time!
