Rifle friendly counties between Newport News and Richmond

[deltaechobravo]

Howdy folks,
I am curious as to whether there are any areas where it is legal to just go out in the woods (with permission from the land owner, of course) and shoot (probably with offsets and other stipulations)? Most of my collection is WWII milsurp rifles, and while York County is fine with me being on private property and shooting my hand guns, rifles are a different story altogether (have to be elevated, have to be hunting, otherwise have to be on a licensed range).

New Kent, Charles City, and James City County are all near by, but I haven't found the time to wade through their respective laws/regulations yet, so I thought folks here might be able to help me out. Thoughts?
