I'm going scopeless for deer this year. A couple of years ago I picked up a Marlin 336C in .30-30 for $159, I think. It was absolutely beat to hell. I cleaned it up and rebuilt it and added an XS rail with the ghost ring. It's shooting Federal 170 grainers at about 3 inches or so at 50 yards which is way good enough for me and where I hunt. My backup will be a 1946 Mosin M44 with either Wolf or Seller & Bellot 180 grain soft points.
I also just built an AR-15 carbine in .300 Blackout, but sadly, we can't legally hunt with semi-autos in PA. I'm hoping to take some hogs with it down south next year sometime though.
As always, my bear rifle will be a Marlin 1895M in .450 Marlin with a Nikon Omega 3-9X40.
