It's super fun, but harder than mounted shooting. With mounted archery your horse has to be trained to just leg cues because when your shooting the bow your using both hands. And you have to be a pretty good archer to begin with. Posted via Mobile Device
My horses are used to gun shots we are avid hunters and sight guns in alot they get over it run around a bit at first now they may look up from grazing at the sound but most times they ignore it Dusty will stand a few feet away while we sight muzzle loaders in and not bat an eye I don't tip toe around my horses they are subjected to alot here as far as noises and activities go I have a friend who is all whispers and and quiet around her horses afraid of how they will react to things..her horses are flighty as all get out they are loose cannons she has no control over them she fears them actually how could anyone enjoy that.
You might be suprised at how little your horse cares about a gunshot. I have a horse that I thought would freak out when I fired a gun around him but he couldn't care less. I shot a couple of rounds from the ground then mounted up and fired a few more without a problem. In fact, I have seen way more horses that don't care than I have that do. As far as horse scaring noises go a gunshot is very abrupt and is over quickly as opposed to something like a dragging tarp.
