The Hammerli 850 air rifle stock is synthetic, making it a great all-weather air rifle. The Rateagun score is just 4.1, which is a fantastic score. Therefore, it is right to say that around 90 degrees Fahrenheit is the high shooting temperature for CO2-powered air rifles. The table mentioned above clearly shows an increased muzzle velocity with an increase in temperature.īut there is a limit on the rise, it cannot be said that it would progress ad infinitum.Īt around 95 degrees Fahrenheit, there is an enhanced pressure in the “ Valve lock”, which makes the muzzle velocity fall rapidly.

H & N field target trophy green 14.66 grain Muzzle Velocity calculated at 90F- Average Muzzle Velocity calculated at 75 F-Average Muzzle Velocity calculated at 67F-Average Here is the breakdown of performance for the accuracy and speed of the Hammerli 850 CO2 air rifle. The speed of the Hammerli 850 CO2 air rifle can never be compared with the real thing as it does not fulfill the need for the smallest number of shots per fill.

Remember that if you choose to shoot at a high temperature, then you may have reduced stringing because the cooling effect of each shot would be less. It was correct at 10 yards but no more than that.Īll the targets were vertically displayed, maybe due to the reason for falling muzzle velocity during the shot strings. The highest muzzle velocity can be found at 95 Fahrenheit at the value of 620 fps.Īfter the HAM test, I can say that the accuracy is not as expected.

This speed is accomplished at 61 Fahrenheit. In the above table, you can see that the highest muzzle velocity is achieved with Gamo Raptor Target Trophy green 5.56 grain, which is 549.8fps. H & N Field Target Trophy Green 5.56 grain Honestly, the barrel shroud executes and matches the plastic parts well.īelow is the table to have an idea regarding the accuracy and speed of the air rifle. The design of the Crosman air rifle is traditional, with black synthetic stock. The Crosman 1077 looks very much like a Ruger 10/22 firearm. Therefore, you can have fun with the family at weekends or in the evening without any risk of disturbing the neighbors. There is no silencer, but one isn’t at all necessary. The Crosman 1077 CO2 air rifle is not powerful, therefore it is not loud. => Read our Crosman 1077 semi-automatic CO2 air rifle review here. The accuracy of the Crosman 1077 CO2 air rifle was good, with 5 of the seven standard HAM test pellets.Īs expected, precision with the Crossman premier hollow point pellets was good. Following is the table to show the speed and accuracy of the Crosman 1077 CO2 air rifle.
