My preferred bullet is the 129 Interlock. It shoots 1/2-moa in my .260 and smucks deer. I would take the Sierra over the SST, though, I will not load SST bullets for anything but varmints.
It is hard to beat Nosler bullets also. I would definitely pick them over the Sierras, if they shoot OK in your rifle.
Let me tell you where you're wrong bro. You see you need that super $2 a shot bullet with its plastic tip, bonding and boat tail to kill a deer.
What you don't know is that the cup and core SP bullet that killed them fine for most of a century simply bounces off deer today.
