Happy Thanksgiving...

First things first - check the DGIF website and read all about hunting, deer hunting, firearm laws, what's legal, what's not, etc...etc...

The good news is that in Culpeper, you can use the .270 rifle as per the regs. Public land hunting is always hard to hunt, as the game animals all have calendars and they know when it's hunting season! LOL...

Good luck!
