Muley,
If what you say is actually true would it not defeat the whole purpose of a variable scope? The whole idea is to have a lower power for in close shots and a higher power for longer range. If the scope is only accurate at the highest power why not just use a fixed power? I guess we have all been duped into wasting our hard earned money on useless variable power scopes.
by the way the scope in question moves 4" horizontally and 6" vertically between 2 and 8 power at 50yds.Not normal!
