Ive been shooting my 155 Terminal Ascent out of a 16.5" barrel at about 2650. Its taken multiple elk, deer and Antelope. I have some 150 ABLR just haven't had time to develop a load for them.
I'd love to hear if you were successful with your 708 this year for your brown bear? I have a 300 wisdom and 708 in ticas, love them both. Also, what ammo were you using?
I have been using this combo for about 2 years now. Its been great! Very accurate out of my 16.5" barrel going 2625 fps. Run it through my suppressor and love it! Looking to build a second light weight rifle in this combo.
