Gun sounds unique to spaghetti westerns

From another message board, if it's of help:

In the commentary track for "Once Upon a Time in the West," there's a lengthy discussion of the way Sergio Leone approached sound in his Westerns. He instructed his sound editor to tweak all of the sounds, modifying them electronically and cranking up the volume to enhance the effect. Leone didn't want realism, he wanted a mythic aural impact, which is why the gunshots, expecially the ricochets, sound so unworldly.

Thank you, that is interesting. It appears though that other makers of spaghetti westerns used the same techniques perhaps using Leone as a benchmark.

They were also recorded in a gravel pit/quarry hence all the ricochets.
