My two Tikka T3 LS 270WSM rifles plus my buddy's in the camo version love the Winchester Supreme 140gr Accubond CT's. They even love the handloads better.
As mentioned, maybe try the Accubonds in the Federal ammo, or the TSX/TTSX's. FOr the WS ammo, maybe try the XP3's or the E-tips to see if they shoot better.
