I just picked up a Lefty Tikka T3 Lite Stainless in 30-06. It is a very smooth operating rifle. I hope to shoot it this weekend and be able to report on that front, but initially I am very impressed with this rifle.
As for caliber, I'm already committed to 30-06 with ammo and reloading equipment so for me it was a no brainer.
Today 08:27 AM
Let me know how the 30.06 does as far as recoil. I am not afraid of recoil, but I figure the .308 would be close to the 30.06. I would get a .260 in the lefty if it was offered because I have taken interest in a medium caliber as the .260.
Also let me mention that I do reload, so ammo is not a problem
