While I am in the process of digging back through my memories, there is a western movie I remember seeing in the 70's, and all I can remember from it is a scene where 2 (I think) men were out the front of a homestead near some horse yards, and another man is riding away flat out on his horse. One of the men near the house has a long barrelled firearm and he takes a shot at the man riding away. The other man says something like "you missed", then after what seems like several seconds, the man riding away is hit by the bullet and falls off his horse.

This is the only scene I can remember. Hopefully someone knows which movie I am talking about!
Thanks.
