The Hornady SST 140gr. is giving me the best combination of velocity and accuracy at 2860 fps in my .260 Rem Savage Model 16. (22" barrel). I've got the tapered point of the plex reticle on my 3-9 Conquest spot on at 400 yds. Will this bullet give me the terminal performance I need on a once in a lifetime sheep hunt here in Wyoming? I am also thinking of swapping the Conquest for a Leupold VX-2 3-9x40 with CDS to give me dial up elevation and reduce weight by 4 oz. Is this worth doing? I've got a nice 6.5-.284 Savage LR rig built but even though I tried to keep the weight down it's pretty heavy for a sheep rifle, 10.5 lbs or so. My 7mm Rem Mag in Ruger M77 and .300WM in Win M70 are a little heavy too. Will the little .260 do the job?
