Maryland’s two-part muzzleloader seasons begins it’s second half this weekend and will run through December 30, 2023.

“The late muzzleloader season is a vital part of the successful management of Maryland’s deer population,” Maryland Department of Natural Resources Wildlife and Heritage Service Director Karina Stonesifer said. “It is a great time of year to get out into the woods and to introduce someone new to the traditions of hunting.”

Muzzleloading firearms may only be used to hunt deer during the Muzzleloader Season, Firearms Season, Junior Deer Hunt Days and Primitive Deer Hunt Days. Hunters may only use flintlock or sidelock percussion muzzleloaders during the Primitive Deer Hunt Days.
