In this performance Field Test Shooting Video of the Barra Cowboy Series 1858 CO2 BB Revolver, I find out what the velocity in fps is using a brand new standard 12 gram CO2 cartridge shooting 4.5mm Steel BB’s through my Chronograph in the Replica Airguns Sea Can Indoor Shooting Range. I then setup a fresh paper target 30 feet down range and shoot 10 rounds into it shooting in Single Action to see how tight of a grouping I can get out of the box. If you have not already watched my Table Top Video Review for the Barra Cowboy Series 1858 CO2 BB Revolver then make sure to check that one out for details and specifications along with some more close up video.
First up for my velocity or fps test of the Barra Cowboy Series 1858 CO2 BB Revolver, I shot 6 4.5mm Steel BB’s through my Chronograph. The slowest velocity was 327 fps and the fastest shot hit an fps of 351, this result averaged 345 fps which was a bit under the claimed “up to” 400 fps from Barra, still a usable velocity for shooting pop cans and the likes at 30-40 feet down range. The temperature in the Sea Can was I would say around 20 degrees Celsius which is 68-69 degrees Fahrenheit, so a decent temperature to get middle of the road performance from a CO2 Airgun like the Barra Cowboy Series 1858 CO2 BB Revolver. In warmer temperature you can expect closer to the claimed 400 fps.
I then placed my fresh paper target on the pellet trap 30 feet downrange and using my standard semi rested shooting position (hands rested on a sandbag up front and sitting on a stool in the back), I shot 10 rounds into the target and was able to get a respective 2.5 inch shot grouping shooting in Single Action of course. I did notice the Barra Cowboy Series 1858 CO2 BB Revolver liked to shoot a bit high, almost 4-5 inches higher than I was aiming but it did center left to right fairly well.
The Barra Cowboy Series 1858 CO2 BB Revolver is a lower cost and almost all plastic Single Action Revolver with only a few internal meat parts in the build, that said it does feel well built and fairly solid in the hand. It may produce that claimed 400 fps velocity by Barra in warmer conditions which is more than enough for plinking and pop can shooting which is really what the Barra Cowboy Series 1858 CO2 BB Revolver is designed to do. I found it to be accurate enough for it’s intended purpose but it did push a little high on the target out of the box, at least my demo unit would require me to aim a little under my intended target by about 4-5 inches at 30 feet away for near bullseye shots as there is no way to adjust the sights manually. The Barra Cowboy Series 1858 CO2 BB Revolver will provide lots of shots per CO2 and has a much higher capacity magazine holding 18 rounds as compared to other shell loading revolvers that only hold 6 rounds. If you’re OK with a bit less realism, then the Barra Cowboy Series 1858 CO2 BB Revolver may even outperform the more expensive and more realistic Single Action Army Revolvers on the market at a less expensive price point.
