My straight wall hunting gun is a 450 Marlin conversion kit for a Desert Tech SRS A2 w/ Dead Air Primal. It currently has an ATACR on it but that's a 3-15x42 in the pic.

I prefer to shoot subsonic and transonic loads with this caliber. The factory loads have a ton of recoil with a 350gr RN at 2200fps. The recoil isn't too much in this rig but they rock me with my Ruger No.1 in same caliber. I use the No.1 to practice off hand shooting and sitting unsupported shooting w reduced loads which right now are a 300gr HP running around 1250fps.

I want to test the Hornady 410 Sub-X this year and 250gr TSX but I usually shoot a 300gr HP or 350gr round nose interlock at steel.
