My Remington 700 CDL in .30-06 is 6.5lbs.
That is unusual, the Remington CDLs I have handled felt heavier than 6 1/2 pounds and Remington catalogs them at 7 1/2 pounds. (That is 7 1/2 before bases, rings, sling swivels etc).

The Tikka T3 lite at 6# 2 oz (including sling swivels, including rings with integral bases) in 30-06 is very light, and I would not recommend it for a novice shooter without a good recoil pad and/or a good brake like Vias, or a Caldwell led sled for bench shooting and working up loads. (I personally do not like brakes on hunting rifles). It will be exciting off the bench. I know I have a 30-06 (custom Remington) that has a finished weight of 7.25 pounds (about the same weight as Tikka with a scope) and it is interesting to shoot. I also own the Tikka T3 lite in 270 and kicks harder than I expected in a 270.
Depending upon your hunting style a light weight rifle can be a great thing. If you don't ever do anything but walk to and from your box stand I would go for a rifle with a finished weight in the 9 pound range, about what a Remington BDL will weight if you include a scope, rings, bases, and sling. (A scope typically weighs in the 10-16 oz range, most slings in the 4-8 oz range, rings and bases in the 4-8 oz range).
If you plan on doing a lot of walking then a light weight rifle is a great thing, particularly as you gain altitude. My light weight 270 and 30-06 are a dream to carry all day and are perfect for hunting out west in the mountains. I love to hunt on the move (still hunting) so a light weight gun is worth the trade offs to me. It all just depends on what your hunting style will be and what your perceived hunting needs are.
If you are an experienced shooter, or are willing to practice it it is not too light. I do highly recommend the Tikka T3 lite, mine is great (probably the best out of the box rifle I have ever purchased).
