I made a short video trying to explain the types of lead I hope this helps someone out there.
"The greater the distance and the greater the speed the greater the lead needs to be."
Absolutely perfect statement. The trick is learning what that lead needs to be and how much you need to alter it for different distances and speeds.
Beautiful!!!
So, do you think about the speed of the creature in terms of mph or just "fast" or "slow" ?
In reading, it seems coyotes might be able to hit about 40 mph at top speed and hogs about 30 mph at top speed ... but typical speeds might be much less, maybe 20-25 mph when moving "fast".
Could you comment on this aspect please?
Really appreciate the effort to educate!!!
How do you determine the distance?
In your videos you seem to know the distances. Do you range with LRF before the video starts? Do you use reticle ranging? Or otherwise?

There are a couple of vids on Youtube that talk about lead on running critters. These are good, generalized vids, but over-simplified. Maybe that is good since most folks won't know all the relevant variables at the times they are pulling the trigger to hit all that precisely. For example, I could not have told you at the time just how far away the pig was as it was running past me in the video, how fast it was going or how fast my bullet would travel that distance...and how far the pig would be traveling while the bullet was in flight (to determine lead). Going back and using Google Earth path measuring (in "Ruler") to get my distances that the pig traveled and distances from me, then using the video's timer in Movie Maker, I was able to determine that the hog traveled about 38 yards in 5 seconds {treeline to treeline}, or about 23 feet per second, only about 15.6 mph.
My second shot at the hog was at about 70 yards when the hog was passing behind the tree. Given the velocity of the Grendel 123 Hornady SST out of my gun, it would have taken about .09 seconds. In that time, the hog would have traveled just over 2 feet. Based on the images, the shot should have hit him in the ham, but apparently the shot hit the tree {and appeared too far back which is why I added so much lead to the next shot}. No ham wound was found. The third shot was at about 80 yards and it would have taken the bullet just about 0.1 seconds to arrive and the hog would have traveled about 2.3 feet in the time. That the shot was several inches in front of the hog's nose resulted in the impact in the shoulder that broke his leg. The fourth shot was just too late.
So the 2nd and third shots could have hit the hog at that speed using the lead method. However, had the hog been going faster (and they can go much faster), then the 2nd shot could easily have missed behind the hog (even if it didn't hit the tree) and the 3rd shot could have been way back toward the lower gut or ham.
It is fun to play with the calculations, but you never know what you are going to get when you are in the field.
