An AirArms .177 caliber S200 Target locked down for testing to find the magic pellet. The Chronograph is also in permament position.
The target is a sheet of 8.5 x 11 copy paper stapled to a Douglas Fir 2x10 that is clamped to a ladder seen in the background at 10 meters. The air rifle is never moved; only the target for initial positioning- then it is never moved. Note the bungie cord is used to hold the barrel snug against the barrel support of the gun vise.
With the vertical and horizontal supports fastened to the window sill and cement floor, with the gun vise clamped to the supports, the air rifle cannot move. Also, with a three foot air line, the AirHog Supreme can be left attached to the air rifle for re-filling after every six-shot pellet weight test.
The horizontal support is securely attached to the window sill with 3" deck screws.
The verticle support is attached to the cement floor with a 1/2" bolt.
