Yes, you can get 338 win mags with a 225gr. Accubond in Federal Premium Vitol-Shok. Also Winchester Supreme has a 225gr. Accubond factory load. I have never shot the Winchesters but I have shot the Federals. The Federal 225gr. accubond is the most accurate factory load I ever found for my 338 win mag. This is all I shot in mine for awhile, then I started handloading for the 338, I only use Accubonds in it.

Here is the Winchesters.

Here is the Federals, I highly recommend these if you dont handload.

By the way, I am no fan of the Barnes TSX either!
