This is straight from DNR representative Samantha Hopkins:That was always my understanding as well. Summer hunt with rifle up until bow season, then again after late muzzleloader. Maybe I always did it wrong, but I don’t think so.
Edit: found this on DNR site, rules regarding time frame are vague at best....

The specified COMAR 08.04.03.02 is equally as vague, but both do reference the wearing of orange during specified hunting seasons, so it sounds feasible that it’s okay.
”A DMP is year round regardless of what hunting season is in. If you are shooting on a crop damage permit in archery season with anything other than archery equipment the deer needs to be checked in on your DMP permit number. If your hunting within the season with the appropriate weapon you can choose whether or not you want to check it in on your personal license or the permit. Keep in mind that if your permit is for antlerless deer only and you see an antlered deer while hunting with a shotgun during archery season, that will not work. Hopefully that clears things up!”
