Target dimensions: outer circle = 4.72"; inner circle = 0.59" Each shot was chronographed, velocity curves were drawn. Each group (30 shots) was done in the green pressure range from 2900 psi to 1305 psi. Groups were analyzed using OnTarget software, showing maximum spread, vertical and horizontal offsets. Homemade IR screens connected to a PC running SoftChrono ballistic chronograph software were used to measure muzzle velocities. Thank you for watching!
