Too many good bullets to try! I've used Bergers (really accurate, but as others mentioned they're designed for break up), Sierra Gamekings (highly accurate but didn't seem to get consistent results) and Nosler Accubond and BT. Accubond was giving straight through with minimal expansion on SC whitetails, mainly due to the size and thin skinned nature we have. Switched to Nosler BT and having good results so far. I'm currently using 168gr BT in a 300WM, but I got the rifle during season last year and didn't have much time for load development. Looking to go up to 180 and 200gr this year. The 168gr shot last year was a head-on neck shot and complete pass through with DRT results. Exit wound wasn't overly large so was happy with it. Took another with a Nosler 90gr BT in 243 at 50 yards, didn't have an exit would but turned everything in the chest cavity to non-working order and DRT.
