i just found out a rdr xp glitch all you need to do is download the new free dlc, then find free roam that when you whistle the horse doesn't show up on the map if you found one go to any headout once you enter you will see that you completed the headout so just keep pressing left button you should get 400xp every 3 sec, i got rank 50 in 3 hours by doing this so enjoy.

damn i knew it must have been patch cause i was whistiling 4ever
