I have a t3 lite, factory rings (oh! the horror) 3x9 3200 elite. No idea of weight. It is a little light for me, I struggle to shoot it in the field sometimes. A Rem 660 308, Brown stock, VX 2 3x9 in Talley lightweights, is perfect. Wish I could figure the deal with that rifle. It is not real accurate, but in real use, it works better for me than anything else I have tried. Probably fit and balance.
I think it's the balance of your Tikka, not the mass weight that is what's preventing you from being as accurate in the field.
