I like the 120gr BT's out of my Encore, 42.5gr of H4895 seems to be the trick in my gun. I never checked the velocity but I have had one deer go 20 yards after the shot and another was DRT. YMMV
Thanks-Ron
Either the 120 gr or the 140 gr BT wold be great in your 308 Win Encore.
Give the 120 a good look, it is one tough bullet. I have actually tested in in water with a 280AI and I was very surprised how well that bullet held up.
Put that 120 gr BT where it needs to go and a second shot won't be necessary.
