This is exactly why I do not do ladder tests. The longest rifle range in my area is 200 yds and it's 50 miles away.
I've read quite a bit about ladder tests and have come to the conclusion that (ladder) testing at 200 yds could raise more questions, or bring about more incorrect conclusions, than it would provide valid information to use as a basis for further load development.
Just my 2 cents. Take it for what it's worth!
