Here's all I have concerning general laws for shooting.
§20-2-58. Shooting across road or near building or crowd; penalty.
It shall be unlawful for any person to shoot or discharge any firearms across or in any public road in this state, at any time, or within four hundred feet of any schoolhouse or church, or within five hundred feet of any dwelling house, or on or near any park or other place where persons gather for purposes of pleasure, and any person violating this section is guilty of a misdemeanor: Provided, That any person operating a gun repair shop, licensed to do business in the state of West Virginia and duly licensed under applicable federal statutes, may be exempted from the prohibition established by this section and section twelve, article seven, chapter sixty-one of this code for the purpose of test firing a firearm. The director of the department of natural resources shall prescribe such rules as may be necessary to carry out the purposes of the exemption under this section and section twelve, article seven, chapter sixty-one and shall ensure that any person residing in any dwelling home within five hundred feet of such gun repair shop be given an opportunity to protest the granting of such exemption.
As far as being on private land shooting (assuming you have their permission) you should be fine if are not near anything (see above law).
As you have already linked, WV has some nonsensical and convoluted DNR regulations that seem to be in place to prevent poaching but could be used to trip you up. The following rule is obviously geared at poachers but strictly technically speaking I don't see where an exception is made for target practice.
Rule 4. (It is illegal to)Carry an uncased or loaded firearm in the woods, except during open firearms hunting seasons.
I am not a lawyer. I hope this helps. Welcome to OCDO!
