My go to rig is a Savage 110 in 7mm Rem mag. I also use a .30-06 Rem 700 when it begs to go out and play. I shoot the Savage better, but the 700 is an old friend. My first deer rifle I got around 20 years ago.
My Dad shoots a Browning A-Bolt in .270 that has killed a ton of deer and has the scars to prove it. I can't even begin to talk him out of that rifle or caliber. He is from the if it ain't broke don't fix it school.
