@FosseFilberto has named a few but there are some others like Sabata and They Call Me Trinity which are also very good.
In all honesty my short term memory is ****ed but i have seen two films which i think are fairly recent. First one starts with a man who's unit leave him to be mauled by a bear and he get's his revenge. Second one has a woman hiring an Indian to help her track down her husband. Both quite graphic and harsh. Names anyone?
