My recommendation is the Winchester Supreme Accubonds. I have used only Winchester Supreme ammo for years and switched to the Accubonds when they come out in 2004 in my 300WM and 270WSM. I reload now for my rifles but my wife still uses the factory Accubonds in her 270WSM.
Great bullet with devastating results. I have mentioned the performance of the Accubonds before in other posts on elk/moose/deer and to confirm the results, my wife shot her bull moose on the last day of the season on the morning of Nov.30/06 with her Tikka T3 LS 270WSM at about 325m. First shot was a miss, but she quickly reloaded as the moose stood there and placed the second shot behind the left front shoulder. The moose dropped, but then got up again, and she nailed him a third time and he made it to the willow bluff. We thought he went in , but as we walked up, we seen the moose dropped at the edge of the field-travelled maybe 20metres. My wife was just JAZZED! Both shots were complete pass-thrus at that distance with devastating results to the lungs. The 140gr Accubonds did their job, and to say the least, I was very proud of her! And to boot, she got us meat for the year, as I was unsuccesful at any elk or moose this season. Not too much time hunting as seasons past.
As for your rifle the 30-06, the 180gr Accubonds are a superb choice for any N.A. big game. I would stay away from the Winchester Supreme Ballistic Silvertips for the bigger game-all right for deer I guess. With the Accubonds, the most part, complete pass thru shoots have (for us) a small entrance wound with huge exits, and I only recovered 1 Accubond bullet. Some people have had it the other way such as this pic.

Federal also has factory ammo in the Accubonds.
I have Barnes TSX to reload with, but as mentioned by horse men, I wont be changing bullet type anytime soon.
The only othe bullet if factory ammo would be the new Winchester Supreme Elite XP3's. Initial results for this bullet looks great, but the price will also be higher.
