Bob,
I was going to tell you to avoid the 117gr SST's. We have shot them thru at least four Bob's that I can think of and none of them shot worth a damn with that bullet. The 120gr NPT is not the most accurate bullet I've seen in a 1:10 twist barrel. I used it for a while on elk hunts and it worked o.k. for a nice mulie buck. The 100gr Hornady IL is a great bullet and so is the Nosler BT. If you really want a heavier bullet, try the Hornady 117 SPBT. If you can find them they always seemed to shoot well. But the 100gr Hornady is really hard to beat for anything you'll hunt with the Bob. Try it and some 4350 before you make too many changes to the rifle. Best of luck!
