I don't know why you want FMJ ammo for hogs. I have hunted hogs for years and hunt with guys that use .270s, 30-06s and other calibers. I use a 45.70 with Hornady leverevolution 325 grn bullets. All use expanding bullets. 150 grn or 180 grn ammo will be plenty in your 06. Remington makes a bullet called a hog hammer and they come in 06. While hogs are tough, they aren't Cape Buffalo or Elephants. I am sure there are gyus here that use 06s for hogs and I am sure they will tell you what they use.
