We have lots of driven hunts in Germany every year, it is one of the best ways to kill boars that infested a corn field.
Use a red dot sight or a very low magnification scope, get practice at moving targets, we have moving boar targets at any shooting range for hunters (I will post a video when Im back at my pc, blasted mobile) and limit your shots to reasonable range ~60-70yards.
Don't use a pea shooter either, .308 upwards.
Best advice so far.
What makes a good running shot shooter?
Well years of on target practice. Starts when your a kid shooting rabbits, ducks, blackbirds, pigeons ect. You might have started rabbit hunting with a 22 as I did. Hell I shot a mess of feral cats running with that 22 when I was a young teen.
Good wing shooters can transfer over to mammals pretty easy, so might want to get practice there.
Every year I would spend a week chasing coyotes in ND, lots of running shots at distances way out there, but the bread and butter dogs always hit the dirt at or under 200. Between 200-400 hit rates start to really drop off, but with proper angles some of these were very doable.
Like what was stated 0-4 power max when running shot, large field of view is critical to success, even if your shooting 400 yards on fast movers. You can calculate leads for animals of different speeds and angles based on bullet time of flight and distance. This is important to do in the beginning so you have something to baseline off of for ballpark leads. Start with close targets and then as you can get consistent hits increase your distance.
My last running deer was a 3 legged doe the neighbor hit in Novembers gun season, he kicked it up and it crossed the property line on a dead run (well for a 3 legged one) at about 100 yards I put a lead on it and stoned it with a first shot hit thru both shoulders. To be honest I wasn't the least bit surprised, expected the outcome.
