You have vertical camera movement

Camera movement is seen by looking at the highlights. Go to 100% and find some highlights to inspect. Camera movement will show up as highlight streaking or elongated bluring in one direction. The 70-300 is easy to do this with, even with VR on. VR is not instant, it takes a little bit to lock on and settle down. At 300mm your crop factor is 450mm - which, at a bare minimum, requires 1/450 second exposure to minimize camera movement (with VR off, or unsettled). Now, beginners might even need a faster shutter speed, especially with a 16mp camera at 100% viewing. By the way, 50% works well in simulating prints up to 16 x 14 inches. Smaller prints, like on 8.5 x 11 paper, can use 25% viewing for sharpness.

Lastly, ALL raw require sharpening before viewing.
