I have a Remington 742 myself, a 1976 Bicentinial model. I have shot factory Remington 150 grain CoreLokt bullets almost all the time. Since you really need small base dies to reload for a Semi auto, I just don't bother. I have other 30/06 bolt action rifles, and I do some reloading for them.
My 742 has been dead on reliable, and fairly accurate with the factory ammo.
My suggestion would be to try some factory loads, and stick with the one your rifle likes.
