I also am running a Bison 16" Recon in 6.8spc. I bought it for a lightweight, fast handling dual purpose rifle for whitetail and something to completely flatten coyote. After many seasons, many deer and dozens and dozens of coyote, it has become my goto rig. It kills coyote like lightning, and it don't matter where the crosshairs are, it's going down. It's extremely close to my 243 with 105s in relation to anchoring coyote.
When I got it, I chose to start with the Sierra 110SGK and it is extremely accurate, affordable and kills very well.
The biggest weakness is low BC but 99% of my shots for a calling rifle is under 150 yards so trajectory is not a huge issue.
I have wanted to try the Barnes 95s and 85s but the SGKs just perform so well I haven't tried the Barnes.
With so much factory ammo and available components, I see ZERO reason to re invent the wheel.
