The Tikka T3 actions are all based on a long action so the debate over weight savings does not apply. The T3 lite all weigh 6 lbs 3oz in all standard calibers regardless if they are long or short actions due to the fact they all are built on the long action. The only thing that I can gain from the 7mm-08 over the .270 is less recoil, shorter bolt throw, and more bullet selection, but all this comes at a cost of slighlty lower velosity and ballistics. Also what would the recoil be like in a .270 or even .270wsm in a 7-71/4 lb rifle scope combo. I like to shoot alot during range sessions, 40+ rounds and I am able to do it with a 30-06, but after 25-30 it gets uncomfortable. Out of the three 30-06 rifles that I have owned winchester, browning, and ruger, I have not been impressed with the accuracy. Don't get me wrong I still love the 30-06, but I would like a more accurate rifle and with this light of a gun I think the recoil would be more than I would like. Right now I am leaning to the 7mm-08, but have not completely ruled out another caliber. So far I am thinking the .280 or .270wsm would work if I need a little more punch. Decisions, decisions, decisions. More that likely it will be whatever caliber sportsman's wharehouse has in stock when I go to buy the gun.
