Rifle scopes are overrated for the vast majority of big game hunting situations. I would get a decent $200 scope and put the savings into high quality binoculars. 
I totally agree, I have a VX3 on my 300, about $300.00. But for me, I hunt Muley's primarily where I spend hours glassing. So, top-shelp binoculars are more important, I use a pair Swarovski's 10x40's. The single most important component for me, aside from good boots.
