Good idea to save the .270 for your son!
Personally I like a .270 better than the -06. The 270 is flatter shooting and depending on which load your shooting from the -06 your drop can vary quite a bit.
I currently have a 270 WSM, which I won also, and it is slightly different than the normal 270 but it is a Tikka and out of the box this is by far better than any rifle I have owned. I used to be a big Ruger fan and still am but since owning this Tikka it will be hard for me to switch back. The action is like butter, it shoots 3 shot groups at 200 I can cover with a nickel which is plenty more than acceptable for a hunting rifle.
If I would have bought this gun it would have been in a 7mm Rem Mag, which to me, IMHO, the best all around most versatile cartridge for North American big game hunting. You packs the punch of a magnum AND you have the flat shooting of a smaller caliber. Flatter still than the 270. Very similar to the 300 Win Mag when comparing projectiles other than minor differences to OAL the only major difference is slightly more powder in a 300.
Right now I have some raffle tickets at a chance to win either a Tikka 7mm rem Mag or a Winchester M70 in 257 Roberts. Hoping I win one of them.
