6x what? I was shooting with a vortex 3-9x40 crossfire and I could barely see the targets at 220 (still hit them but it was a struggle). I took a few shots at 400, and I couldn't even see the dust from the hill in the scope.
I agree, the other day there were some guys out there shooting at a plate. Said plate was 90deg to the firing line because one of the chains had been shot and broke. They were taking turns hitting the edge, getting it spinning and winding it up. That right there is a reason some smaller plates or spinners are needed out there.
