Picked up the Simmons Aetec 2.8x10 - for my featherweight 270. I have an old 44mag on my 300WM sako that never let me down so can't complain about the simmons quality becuase everything I own gets abused a bit. I checked the scopes for field of view and brightness and think the AETEC is the better scope. I wouln't put on the front extender though - cuts down on light transfer I think.
