This year, the world saw a long-theorized weapon in action: a commercial drone, like a person might find at Best Buy, dropping a bomb on a target in Iraq. These drone bombers, used by the ultra-violent quasi-state ISIS in Iraq and Syria, are the flashiest combination of modern technologies with the modern battlefield. Cheap, camera-carrying robots, put to nefarious ends by a group that could never otherwise dream of fielding an air force. Dropping grenades isn't the deadliest thing an insurgent group can do with a small flying robot, but it leads to a very important question: What, exactly, is the answer to such a drone?
[...] Here is just a short sample of the more out-there anti-drone tools: net guns, drones carrying nets, squads of drones with nets, drones with net guns, and a smart anti-drone bazooka that fires, you guessed it, a net at a drone (we liked that last one). There was a vaporware drone concept that ensnared the propellers of other drones with wire. A Russian firm floated the concept of a microwave gun, to fry the electronics of hostile drones. And most famously, there are the Dutch police eagles, trained to snag a drone from the sky.
Part of the problem for law enforcement, the Pentagon, and other entities trying to protect against drones is that they're cheap. Workable quadcopters cost as little as a couple hundred dollars. Is there a way to knock drones out of the sky that's just as cheap as the drone itself?

Bottom left.

Yes - bottom left. #12 shot is very small, and it's extreme range is about 40 or 50 yards. Defining "extreme range" to mean, the shot has so little energy left, that it isn't going to penetrate the bird's feathers, let alone his skin. #1 shot extreme range is about 225 yards. Extreme range isn't the bottom of the arc, but rather, the end of the (more or less) straight line, and the beginning of the downward arc. Ought or double ought buckshot will get closer to 300 yards, but as I stated above, it probably won't reach 300 fired from a standard 12 guage shotgun.
I can't find "ballistics" for ten guage shot or slugs, but a couple near-misses suggested this site for more info on 10 guage loads. It seems you have to pay for their manuals in order to get the info. http://www.ballisticproducts.com/default.asp [ballisticproducts.com]
Anyway - to reiterate my earlier point, no one is knocking birds or drones out of the air at 300 yards or meters with a standard 12 guage shotgun, or with a standard 12 guage load.

Sure #12 is shorter range but I wasn't talking about #12 I was talking about birdshot. Everything on that scale is included, with the most typical probably being the 7 1/2 about the middle of the chart and both extremes included. You can cherry pick #12 I can do the same with #1, are you trying to have a conversation or win an argument?
With 7 1/2 or 6 it will definitely still do damage if it hits at near to 300 yards, and it can definitely get there, especially if you use a 40deg muzzle instead of the 30 shown in that chart.
"Anyway - to reiterate my earlier point, no one is knocking birds or drones out of the air at 300 yards or meters with a standard 12 guage shotgun, or with a standard 12 guage load."
Way to completely miss the point. I made it perfectly clear I was talking about ballistic range, not accurate range. You're not likely to hit a bird at 300yards because the pellets are spread out so far the bird has a good chance of flying right between the pellets, but they'll still kill if you get lucky and hit, they can still break windows and injure people badly at that range if they hit.
So when the prior poster was saying that it was unrealistic to think they'd be effective at *half* that range, in a military situation (which means that unlike bird hunting no one is going to stop you from getting a dozen guys or more all firing at the same object at long range in order to get a good chance that one hits) I had to call bullshit. And it's still bullshit. The ballistics absolutely work out that far, you just need several shots to get enough pellet density that hits start to become reasonably likely.

You could save me a lot of time by saying what you mean instead of pointing me to a video perhaps?
