For your 06' anything in the 150-165 grain class will adequately take out any deer.

I hand load them for my father in law and his specific rifle ( a sporterized 1903 A3 .30-06) likes the 168 grain. Specifically the Combined Technologies "lube-lox" coated ballistic-tips. Your going to find out that every rifle no matter what the make is going to have it's own likes and dis-likes when it comes to ammunition. Get yourself a few boxes of different brands and weights and spend a day at the range. You will be able to determine which will perform the BEST for you and your rifle.
