Yes and No. It depends on the type of firing system. There are 5 different type of firing systems used in airguns and rifles. (See the link below. Read the section on Air Gunning Systems) to get a better understanding of how they operate.
Break barrel and Nitro systems always have a consistent firing force. Because you have to cock it each time.
Pump systems also have a consistent power for the same reason.
C02 Will loose power after around 30 to 40 shots.
PCP will loose power after around a certain number of shots depending on the size of the pellet. An example would be an "Air Force .177 caliber Condor air rifle" can produce up to 100 consistent shots, but change the barrel to a larger heaver .25 caliber and you may get only 75 consistent shots. A 50 Caliber PCP rifle may only get 5 to 8 consistent shots because the pellet is so large and requires so much air to drive it downrange.
A rifle, i supose
Don't put as much air in the rifle. If you have a dial to set the power then use it. As you shot the power drops. You can dry fire some PCP air rifles.
