T3 Sporters have the factory Set Triggers ,which is one of the sweetest triggers .I think around 400$ to buy the trigger
I have owned 223 & 308 Sporter 100 yrds under 1 moa. 223 a little fussy.I have a 260 Sporter and a Tikka Tactical 300wm in a Sporter stock , with a Set Trigger.
I had a Tikka TGR 308 , shot 27 rounds ,did not like the trigger compared to the Set Trigger sold it( Liked the stock)
All the Tikka s I have shoot were under 1 moa, 223 , 22-250 Varmints, I have not shot any Lites ,but what I have read and others have told me they shoot 1 moa and under.
308 and 223 Hornady Steel Match ammo was excellent ,one hole in my 308 at 100 yards
You can not go wrong with a Tikka
