A sub 1/2 MOA rifle isn't unbelievable it's actually getting fairly common with bolt guns and target AR rifles. But your claims have been far less than that with the Nemesis. What you've shown us here isn't a .1 or .2 moa rifle as previously claimed.
Now we get to the video "evidence". Why is it in those sections? Why would you not simply set up the video, show the distance to the target then focus from behind the firearm showing you shooting down range? Walk to the target with the camera after the line is safe and show the targets? All in one unedited, continuous recording? I don't need to see you walking to the target. I just want to see your targets at 200 yards being the only ones up (ie none closer as well) and that it's at 200 yards. I have very little experience video taping but even I could figure that one out. As it stands now, you could have shot those groups at 100 yards. There is no way to tell. That being said I have shot 1/2 moa at 200 yards consistently so that part is still possible. Then again I was using 168 Federal Gold ammo at $1.80 a round not 140 MFS cheap Surplus. But again it's a far cry from the .1 or .2 claims.
Also why would you use that ammo when you have custom reloads? I don't shoot 140 grain MFS stuff out of my rifles if I have reloads that shoot the way you've stated. Sure it's nice to know that crap ammo can shoot 1/2 moa out of this rifle but what a waste of barrel life. Especially when using this as evidence against accuracy claims.
At 200 yards if everything is on the up and up then you're a good shot. But.. not as amazing as your claims.
Now we get to the part that really makes me suspect. I'll label this under the general heading Social engineering. The first part of this is people wanting to believe what they are being told. A person making less than legit claims is often able to do so because the other parties want to believe it. The second part is selective incompetence. When confronted about something that doesn't make sense a less than truthful person often claims they don't think like that or "I don't know" as their reasoning. The person has reacted normally in every other manner except this one thing which creates a credibility issue. So in that case, there's more to it than what they are telling you. They are not "naive or suddenly stupid" with only that one aspect as they hope you will believe. This is done to explain away an obvious inconsistency and goes back to the first part with people wanting to believe.
So how does this fit? Well here we have someone with a very expensive rifle, a nice scope and a decent shooter. Yet they are suddenly completely computer handicapped and that is somehow used to explain why they couldn't figure out an easy way to show that they are in fact shooting at the range they state. I'll excuse the ammo choice since maybe it was some type of prelude leading up to the match grade handloads. But let's look again at the way this was recorded. This thread would have us believe that someone capable of making meticulous choices in their equipment, including reloading which takes a lot of thought and attention to detail is somehow not going to think through how to prove their claims, because they aren't familiar with computers or electronics. Ya I don't think so. The electronics have nothing to do with thinking through how to present this. The presentation is where the inconsistency is. The unfamiliarity with electronics, computers etc is the red herring designed to draw attention away from the fact that these videos don't prove what they were supposed to.
