Yeah, I would skip over the package deal as well. The scope that comes with the package, as well as the mounts/rings, might not handle the 300mag before too long before it all lets loose.
I picked up a Savage package deal in 270 wsm a few years back. I had no intentions of buying a package deal but it was $20 bucks cheaper due to a sale that was going on. The bases and rings were made of aluminum and I have no doubt that there would have been problems had I not immediately replaced them. I put the scope on a .22 and threw the rest in the garbage.
