Equipping a dynamite stick and using Dead-Eye targeting while aiming at a cougar sends your dynamite stick straight towards the cougar like a homing missile, exploding on impact and killing it. An idle cougar also spawns in the grass on a hillside North of the South-most road out of Blackwater; if carefully approached from the East, it is possible to take this cougar by surprise and blow it up before it becomes alerted.
Rattlesnakes can be found in abundance at El Matadero within the perimeter of the safehouse there. Listen for the hissing noises, which can be used as a guide to find the snake and kill it. If no more snakes are in the area, save the game at the safehouse there until the next day (they don't appear at dusk or night), then re-load that save to make them spawn again. Note that shooting a snake in the presence of a lawman may trigger a bounty if the player does not have a high honor rank. Rather obviously, they can also be found around Rattlesnake Hollow, however they do not often spawn there and are not attracted by Bait.
A good tactic for getting the 5,000 pounds of meat is to kill War Horse, skin him, rinse and repeat. Horse meat weight about 460 pounds. Do this 11 times and you will have a little over 5,000 pounds. You could also kill cattle with your knife on the MacFarlane ranch. Much more humane than killing your beloved horse and quicker.
Rockstar released an unfinished version of the DLC for PS3 on the 1st of September in Europe and on the 2nd of September in other countries except for the United States. This version was reported to be untested and full of bugs. R* recommends to anyone who downloaded this version to delete it from your console and wait for the tested and finished version, which is out now.
Combining this outfit with the bandana creates an interesting new look for Marston. Due to the unique badger hat of the outfit in conjunction with the bandana, only his eyes will be exposed.
The headpiece of this outfit appears to be of a badger, though there are no badgers in the game world.
In Undead Nightmare DLC, an old man is seen wearing an outfit incredibly similar to this outfit, the most notable part being the hat.
When the player is wearing this outfit, any cutscene will be automatically skipped.
The hat from the Expert Hunter outfit looks similar to the hat worn by Robert Redford in the 1972 film "Jeremiah Johnson". The coat is also similar to the one worn by Will Geer ("Bear Claw" Chris Lapp) in the same film.
