Windage would be a MUCH bigger problem than elevation were that the case. Plus PTRDs only had 2 elevation settings, I don’t think either were very long.
I’m actually surprised windage isn’t an issue with how far offset the sight is from the barrel. In War Thunder it goes to a ridiculous degree with some tanks how much you have to correct left or right with range.
Not to mention the ungodly high velocity on the cartridge. Scratch my origional post. If this was the cause of elevation zero, this would be a 10km zero.
I haven’t played moscow since the smg premiums were put in. But from my experience, it always shot high until several hundred meters out due to that being the zero and height over bore.
