RE: Need help picking out a .270 cal rifle
My .270 is a browning BAR and it shoots amazingly well. Though I have since become a bigger fan of bolt actions.
Remington 700, or Browning Abolt are great places to start, I'd choose a push feed over a controlled most likely, Sako 85 perhaps. Ormaybe a weatherby vanguard sub-moa....
I'd put at least a 3-9 on top of it, with a strong recommendation on a 4-12 or 4.5-14 type.
