A quick Google search shows birdshot has an effective rang on the order of 40 - 50 yards. Now, you still have to be competant with a shotgun, but the public perception of shotguns is generally skewed. They have a much tighter spread and longer range than movies and games would have one believe.
This is about drones that are cheap and can shoot you with a bullet. Sure a +1M$ drone will kill you from behind the horizon, but a repurposed consumer drone operates on the same ranges as handheld guns and as such could be shot by a handheld gun. If you can hit it, which is why you use a shotgun to increase your ods
it's not necessarily with a bullet. Most improvised attack drones drop explosive payloads, since it's both simpler to set up and simpler to use. Outfitting a drone with a gun takes making a complicated system for aiming it, while a payload drone just needs some 3d-printed parts, some extra wiring, and usually just a single servo.
Are the cheap drones really shooting people with bullets? I was under the impression they just had small explosives strapped to them and were single-use.
you're correct, they do not strap guns to improvised attack drones. they're not necessarily single-use either, though. A kamikaze drone will detonate its payload while its still attached, which is an option. There is plenty of footage of IADs which use a servo to just physically drop a payload onto targets from above, and those could potentially be used over and over. I think the kamikaze version is able to be more effective, for a variety of reasons, but both versions seem to be seeing use.
I'm guessing you mean just the disposable kind of drones popularized in Ukraine? We've been dropping hellfire missles from Reaper drones at 10,000+ feet for a couple of decades now.
Go to YouTube and search "Ukrainian drone drops bomb" and you'll find tons of them. Like this one where the soldiers had no chance of hitting the drone.
