At 300 yrs that line about Coriolous is total BS. Generally horizontal stringing is wind gust or the shooter....
A lot of it is the shooter, even with a scope with poor parallax, it is still on the shooter. However parallax can be an issue. It could also be a rifle issue. Poor bedding or pressure on one side of the barrel etc. etc.. Someone also asked what kind of front rest or bags or bi-pod he's using, with no response from the op. He's likely on a fishing expedition. Also what you have here is a guy that has been telling us how good his scopes are, yet he can't figure out easy issues. Recently he has had issues with a high dollar March scope. He said he couldn't even hit the target and his buddy kept telling him he was shooting over it. There are some guys that can figure this schidt out and others that just don't get it. They never will..
