When I wanted a T3 lite stainless in 260, they were not available. So I had one put together with a high dollar aftermarket barrel. Cost me twice the above price, but boy howdy it sure will shoot great. Mostly I shoot the Nosler 100 gr Ballistic Tip for coyote, pigs, and deer. Works fine, though I have noticed that the 120 gr BT puts big pigs and deer down quicker. The 100 gr is over IMR4064 (near max) and the 120 gr is over R17 (at max).
Hey Kirk, welcome to the fire. that is a SWEET Carbine you had built, fyi, I went w/a 6.5x47 last minute. It would be nice if they offer the SS in 260.
Your rifle should be the blueprint for what a T3 should be, in contour
What's the magazine length situation with the 308-based T3 rifles? Seems like I remember them having rather short allowable OAL's? I'm not up on Tikka these days, but like what I hear with regards to accuracy.
