All of this firing was slow and deliberate with the Oehler three-screen chronograph used to measure velocity and targets placed downrange at 25 yards.
The laser beam source can be observed from downrange and could serve as a target.
We sent more rounds downrange with this setup, shooting out to 330 yards.
With just a little instruction both adopted good prone and sitting positions and began to easily pop steel targets 70 yards downrange .
Now go downrange and compare the marked target to the one you fired at.
