I got timed out and had to restart this post ..... sorry. So I'll try to correct it.
Talyn, you're correct in that it's only my opinion. But it's an opinion based on many years experience in shooting in general, instructing in specific, and in "Zero'ing" many rifles.
The real issue I had here is that he still hasn't "Zero'ed" anything. What he has done is to get his rifle reasonably on target. There's a significant difference. And he's shooting at a target set at 25.5 yards according to his own statement and measurement. Then he claims he's "pretty close" in several instances. But he doesn't explain that if he's off by only 1/4" at that range (in windage), he'll be off by or close to 1+" at 100 yards. Or that at 25 yards he'll need to change his scope setting four times the number of clicks to correct his "off a little" than he would at 100 yards, or to get the same amount of movement at 100 yards he'll have to move his scope setting 4 times less and why. And neither does he explain the difference between windage and trajectory. There was at least one instance when he was off "a little" on both I believe.
But it appears he's 'off' only a very small amount at that 25.5 yards, or in his words .... "a little". We can only guess how much, but, going by the apparently very small amount of change he made to his scope, it's not likely he would have moved his POI enough to actually see that difference on paper or steel. Especially considering he's shooting from a somewhat 'squatting'/'bending' position and from a bipod. C'mon, by no stretch can that be considered 'Zero'ing' of any rifle.
And then he fires one round and exclaims he needs to adjust his scope's reticle and then goes into a confusing dissertation of how the reticle moves in a different direction than he wants to move his POI, but doesn't explain why, or the correlation between the clicks/index marks on the scope turret to how far it will move/change his POI. Neither does he appear to understand that one shot typically is not and typically cannot be a true indicator of real POI compared to POA. Neither will a relatively new shooter. One who will fire one shot, then adjust his scope for that shot. Shoot again, then adjust the scope for that shot, and on and on.
He doesn't seem to grasp that with that one shot he could have pulled the shot, jerked the shot, flinched the shot, or any other number of reasons why that one shot may not be a good indicator, nor does he mentione that. I don't think I know of any professional instructor/trainer who would ever suggest adjusting a scope or any sight based on just one shot.
Now I'm going to just stop here with my observations of his video and his instructing technique since I'm not looking to offend anyone nor hurt any feelings. I even made mention that in my opinion he was "a 'putzzzz', at least in that video." implying he may not be a 'putzzzz' in any other endeavor. He may be a fine young man, experienced in many things, even firearms. It is his instruction technique I questioned, not his experience specifically, I'm pretty sure.
So again, I'll apologize to anyone who was offended or to whom I didn't make my intention clear. I would probably enjoy sitting down with him for a cold one most anytime, I just wouldn't want him instructing my kids or grand kids in anything relative to firearms.
