I finally got the chance to do my first official Field Test Shooting Video Review using the Caldwell Ballistic Precision Chronograph and like my Test video everything went really well. I was a little bit scared since my first round through it shooting the Crosman DPMS SBR CO2 Blowback BB M4 was a "no read" but then the following 5 shots where all good. I think my shot placement was just a tad off on the first shot as I adjusted my aim a bit for the tore 5 shots. So getting to the results of the Crosman DPMS SBR CO2 Blowback BB M4 Air Rifle... I was using a somewhat used set of 12 gram CO2 cartridges that I had previously shot a couple of magazine through shooting in a bit of semi auto and full auto so I would assume I had at least half of, if not a bit more of my CO2 left in them. The Crosman DPMS SBR CO2 Blowback BB M4 was also fully warmed up and it had been a day since I shot it last which lets the CO2 and the gun warm up and pretty much perform as if it was using new CO2 for the most part.
