None taken!
I should admit that I've had 6x scopes on varmint rifles in the past, and probably will again. The last one was on a .220 Swift, partly because a 6x36 Leupold was the only appropriate scope lying around loose when the rifle showed up.
Probably have shot 85% of the coyotes I've killed with 6x, whether the scope was a variable or fixed. In fact the last one I killed was with a 6-24x I was "field-testing" set on 6x....
