*facepalm*
So many things wrong here. Ok, lets start with the shooting PRVI ammo. I shot it from my D166 M28/76 action, and it did not do that. Fouled like mad, was not particularly accurate, and I just did a few as a test. But I know from my seating tool how liberal the lands are on it. Especially compared to the non D166 M28-76 I have now.
Shooting a bullet a thousandth over is pretty common, and a .310 bullet on a .3082+wear bore is not the critical thing as much as the throat, hence why a D166 was done to accomodate Russian ammo.
D166 expands (lengthens I would guess) the throat so that the fatter bullet will not jam on the smaller bore, which it could very well do and appears to BE DOING in this video (so sad).
That is why he has a tough time closing the bolt. It appears to be creating a headspace gap and he bellingerently ignores the dangerous sign of blowback and perhaps a lot of pressure(in his face no less).
He seems to indicate it did not group for him well, and nobody talks about BABY like that!
He needs to tighten the cant on the bipod for good groups, and then there is target selection.
Shooting the diopter is GREAT for high contrast circles. I have just been amazed by what groups I get shooting at a tiny dot:

It's the circle in a circle in a circle effect...crazy man.
Silhouettes I have found...tricky. Nothing like that. Not even close....actually seems more like what you would expect iron sight shooting to be. I score nice hits, but very inconsistent sight picture. Different front inserts help that.
