My father has a .30-06 that seemingly shoots most factory loads of 150 through 180 grains an inch or better at 100 yards. I once tried these loads on paper just for fun - groups were about 4" to 5" - ouch!
I think that the problem with accuracy in these loads is due to the sabot.
On the other hand, a friend of mine has a 30-06 that seems to shoot these loads much better - about 2" - not good, but better than the 4" to 5" my father's gun was getting.
My friend used this load on a 75 lb. Texas whitetail doe at about 50 yards away. He shot it right behind the shoulder, closer to the heart. The deer ran about 50 to 75 yards. When he cleaned it, the bullet completely disentegrated. BTW, .22 caliber bullets are allowed in Texas.
