To continue from DontTreadOnMe's post, you can even have the loaded magazines and the unloaded guns in the same range bag *if* the range bag is set up with pouches that close with a fastener (like velcro or a zipper) that provide "complete and separate enclosure" for the magazines and handguns.
For example, my range bag has a main compartment that zips closed and external pouches that also zip. So, even without a license I could put the gun in the main compartment and the loaded magazines in the outside pouches, and even put the bag on the front seat beside me, and as I read it, be perfectly legal.
Here is the definition of "unloaded" from ORC 2923.16
(K) (5) (a)
(a) "Unloaded" means
, with respect to a firearm other than a firearm described in division (K)(6) of this section, that no ammunition is in the firearm in question, no magazine or speed loader containing ammunition is inserted into the firearm in question , and one of the following applies:
(i) There is no ammunition in a magazine or speed loader that is in the vehicle in question and that may be used with the firearm in question.
(ii) Any magazine or speed loader that contains ammunition and that may be used with the firearm in question is stored in a compartment within the vehicle in question that cannot be accessed without leaving the vehicle or is stored in a container that provides complete and separate enclosure.
(b) For the purposes of division (K)(5)(a)(ii) of this section, a "container that provides complete and separate enclosure" includes, but is not limited to, any of the following:
(i) A package, box, or case with multiple compartments, as long as the loaded magazine or speed loader and the firearm in question either are in separate compartments within the package, box, or case, or, if they are in the same compartment, the magazine or speed loader is contained within a separate enclosure in that compartment that does not contain the firearm and that closes using a snap, button, buckle, zipper, hook and loop closing mechanism, or other fastener that must be opened to access the contents or the firearm is contained within a separate enclosure of that nature in that compartment that does not contain the magazine or speed loader;
(ii) A pocket or other enclosure on the person of the person in question that closes using a snap, button, buckle, zipper, hook and loop closing mechanism, or other fastener that must be opened to access the contents.
(c) For the purposes of divisions (K)(5)(a) and (b) of this section, ammunition held in stripper-clips or in en-bloc clips is not considered ammunition that is loaded into a magazine or speed loader.
