I see a problem. In the top video, the case, (.223 or .204) hits the bottom of the scope tube, bounces off the loading port and falls out. That is not a cleanly ejected case.
The bottom one is the same. When the brass comes out in an erratic fashion, it has hit the scope tube in some way.
Your video proves the point of an ejection problem.

Like this one:

Here you can clearly see the mouth of the case hit the body of the scope tube, pause a bit and luckily flops out.
I am not going to claim all Sakos have an ejection problem but I saw enough to realize that my sample of two did not perform to my satisfaction.
