Using 140 fusions in my Tikka. Several deer now without issue.
I've used the Fusion 140's on several cow elk with excellent results.
I just left the shooting range after testing some 140gr Sierra SPBT bullets and W760.
They shot great. Same place as the 129 Hornady Whitetail loads @ 100 yards - so, excellent!
Since I have several boxes of the Sierra's, that's going to get the bulk of my attention for now.
