There are SOOOO many adequate deer rifles out there.. Much depends upon the terrain you hunt...
My current favorite is a Rem M700 mountain rifle in 7mm08... The scope is a Burris 2x7 and it works fine in the woods or in the open country out to 300 yards or so..
If I am hunting the wide open spaces, I use a Winchester M70 in .280 Rem with a Leupold 6x fixed power...
