That video is wild. I've never seen them just keep on coming like that. It's usually 1 shot and everything scatters around here.
I would say in general, yes the same thing happens in the areas I hunt typically. However, there are four things that I believe make a major difference in calling in multiple coyotes on a stand even after your first shot.
1) shooting suppressed definitely helps as well as shooting quieter calibers. I realize the majority of sound happens with the breaking of the sound barrier, but I swear the coyotes don’t spook as easy with smaller calibers as well as shooting suppressed.
2) not mag-dumping on additional coyotes, as well as only shooting at standing coyotes making sure you only have to shoot once per coyote.
Also, my call is almost always muted before I shoot number one. When a second or third coyote is leaving, if you often switch the sound or start it again, they will stop and check it out. I’m usually doing some type of coyote distress or fight sound to stop them. In this video example, you will see coyote #2 looking to my left as I had hit my stopping sound immediately after shooting #1. It was looking at the call making for an easy follow-up shot.
I absolutely love the foxpro foxgrips. I have the ability to mute and play the call with the button on my gun grip. I have a 2 button remote on my tripod leg for my left hand so I can change the sound. I also have my remote control mounted for easy access as well on the other tripod leg. This gives me 3 different ways to mute/play or switch sounds with very little movement.
What I am getting at by all of this is, it helps to have immediate control of your sounds, and if you can read coyote’s body language, you can often stop them before shooting and after.
3) you typically need to change the calling sequence to continue triggering coyotes. In the example of this video, I got super aggressive with the last three coyotes to get them to commit after shooting the first two.
4) a high population of coyotes definitely helps. If you watch the times on the videos, you will see there were two waves of coyotes. There was the first three and then the last two came about 10 minutes later.
