Picked up a couple of Dans over the last year that had not been shot or chronoed so while out doing some extensive tests on a new AirForce Condor SS took the new BSs along.
Someone shortened the butt slightly on this one...
In looking at the plate again it is incorrect...there are only three holes above the one hole group. so 4-5-6-7-8 all went in that one hole...distance was 10 yards.
Sighted both guns in after doing the chrono work with 6 pumps. The extreme spreads for the 4-5 shots it took to sight each gun in was less than 7 fps. Velocities were always right around their initial reported velocity. Both guns were shot with the standard 14.3 grain Benjamin Cylindrical pellet.
