On the target you pointed out that the need to move the POI, SINCE THERE WAS A GOOD SPREAD ON THE POI.
That's all I'm asking,
Okay, windage and elevation have nothing to do with tightening groups. That has to do with having a proper zero for the distance. You can shoot a very tight group and not have a properly zeroed gun. You can shoot a big group with a properly zeroed gun.
In the video, it appears that the scope is not properly zeroed and the group size, in part, appears to be due to the fact that the shooter aiming at the exact same point each time. Part of that will be the ammo as well. He appears to intentionally be aiming low right in order to be able to hit the target, his bullets impacting high left, some almost off the target. When the goal is to simply hit a target, in this case, the gong, group size really isn't critical so long as it is smaller than the gong.
He then says he knows coyotes are in trouble because he has his "bad boy shooting deathly/definitely[?] minute of coyote kill." This is interesting. What I have noticed in the past is what when folks start talking about "minute of _____ {insert animal name here, e.g., hog, deer, coyote} that what they are in fact saying is that they don't have a properly zeroed scope and that they aren't going to bother zeroing further because they think they can kill with it despite it not being fully zeroed. Looking at the video, it would appear that on his 8" target (assuming it is actually 8") that his shots are impacting about 4" or so high and left of the POA. In other words, he has room for at least 2 MOA of correction for a proper zero. Given the scope's capabilities, I am not sure why he has not refined the zero.
