simulating a long range shot

[fng13]

I don't think this is possible but is there a way to simulate a long range shot? I currently only have access to a 100yd range. Would shooting at a very small target be enough?

I know there are a lot of factors that come into a distance shot. But if the target was very small wouldn't atleast some of those factors come into play, such as wind drift, trigger control etc.

If the small target is a decent idea, any idea of how small that would have to be?

thanks.

after posting this I realized that would be no different then simply shooting tight groups. Please disregard this post unless I missed something further
