Once you get into control work instead of sport hunting then it is a numbers game. Methods change. It is about results and not about that one shot kill. At least with pigs, anyways. It is straight up all about stopping as many peanut gobbling mouths as you can. So running shots, long distance shots, bad angles, low probability shots, whatever.
By no means am I saying randomly blaze away slinging lead all across the countryside. Not at all. But each and every shot a person takes has some probability of success. It might be 99% or it might be 10%. The only way to make those percentage numbers better over time is by practicing those shots. You have to shoot at running pigs to get better at hitting running pigs. It is just that simple. You can increase your odds by reading body language and predicting what they are going to do so you can time trigger pulls for better percentage shots. A curving shot with aspect change is harder than one running straight and clean. The more trigger pulls you get the faster you learn. Sometimes your when you are really in the zone it is like your subconscious brain takes over and just knows when the shot needs to break without thinking, it just happens.
Oh and for sure, video helps immensely with the learning curve. Since I started shooting thermal and recording there have been many times I go back and watch video and thing "That is not how I remember that happening." It helps so much seeing what I did right and what I did wrong.
Man, you nailed it, Jeff. When asked to help with predator and hog control is when I started shooting more runners. Unfortunately, my learning curve has been a bit longer without the benefit of the videos, but I have benefited greatly from others' videos in lead estimations.
I use your, and others videos to "visualise", as David Tubb calls it, the correct sight picture required for a 10X shot, and it seems to help just as much w/moving targets as it does in match rifle fixed target shooting. Practice makes perfect and even "dry firing" practice is beneficial. Got there a long time ago on offhand, stationary targets, but can't say I'm there yet on the runners.

You know you're getting there when the rifle just goes off at the correct moment without that conscious "pull the trigger" thought.
Keep those videos coming.
