I thought about a 270 wsm in a LA for the 170 gr Berger but I have a 7mag 8T already. I think a 270 wby mag with that 7.75T barrel shooting the 170 gr Berger would be a sweet LR hunter. A mark 5 or Razor HD LHT scope, something lightweight would be the right choice. Terminus Apollo Lite/Ti is the action Id use to cut weight. I am pretty sure a McMillan ultra-lite Game Scout can be opened up enough for that barrel and would use that. Or a AG Composite. The best brake is the Hypertap hands down, but loud.
