How would I go about doing this? I have plenty of close mic'd rifle sounds. I don't have any shotguns that I've recorded so I took 3 samples of the rifle sounds, delayed them each by a little bit (1-2ms) pitch shifted maybe an octave or two lower. But The guy I'm working for wants to make it more of that typical beefy shotgun sound. Attached is a sound I was working with for reference sake.
