The thought of putting a Bushnell 6500 on one of my CZ455's became a reality when I purchased a 2.5-16 x 42 with the DOA reticle.
The same scope but with a Mil Dot reticle went onto the American and sighted in at 100 yards.
The group at 25 yards was about 1.5" high and probably the first dot above the cross hair would provide "minute of gopher" accuracy.
Shooting at 192 yards, the bullets dropped into a group that measured 2 3/8's and 2 3/4's using CCI MiniMags round nose.
Using that drop and adjusting the power to 10, the fourth dot became the point of aim to hit one of those orange balls suspended on a string.
When the balls was allowed to settle it could be hit 50% of the time. The trick was to let it settle as there was about 4" of movement both up and down and right to left.
Reminder: Shorten the string!
