RE: bullets
For deer I like the 130 grain Core-Lokt. They're not the "greatest" bullet in the world, but they group in my 270 and they're not too expensive. Plus you can get them everywhere.
I didn't like the Core-Lokt on bear. I shot one with CL's and one with Fail Safe 140's. The Fail Safe's were a better bear bullet....at least in my case. The Fail Safes cost more than twice the CL's though.
But like Kirkl said...federal makes good ammo.
Just but a box of several diff kinds and have a ball shootin em up! That's the way to tell.
