Hi D.E.S and welcome to TFF! Although I have never shot the 30-30 Win. I have used both the Speer Grand Slam (160gr in .270 Win) in my rifle and it is a fine bullet. It is one of Speer's premium line of bullets. The only thing you might also consider is the Federal with the Nosler Partion 170gr. I have also used Noslers and actually prefer them over the Speer. Either way, at the price you mentioned, you cannot go wrong. Pick up a box and try it in your weapon. Good luck and let us know!
