PCP carbines versus CO2 carbines, which is better?

We have previously discussed PCP carbines and CO2 carbines separately.

In recent years, PCP carbines have won the game over CO2 weapons. The PCP is the most widely used system in some countries such as the United States, France, Germany or Great Britain. Countries in which they are used for leisure, hunting and in different types of competition.

Precision PCP carbines vs CO2
PCP air rifles are the most accurate air rifles on the market, even more so than CO2 air rifles.

The very high precision that PCPs by their nature, added to the large number of accessories to improve an already very high precision, has caused more and more professional shooters to opt for this system for high precision tests.

PCP carbine power vs CO2

The technology and constant development of PCP systems has not only allowed us to enjoy great improvements in scopes, but also the power of these weapons has been increased, as well as their firing capacity and optimal air regulation systems.

There is a wide variety of weapons and powers within the PCP family. However, we must remember that in Spain the maximum power allowed is 24 joules.

CO2 is not such an explosive gas and that makes the power of a CO2 carbine much more limited.

PCP carbine autonomy vs CO2
PCP carbines usually have a range of between 80 and 100 shots. CO2 carbines usually use tanks that offer a range of between 20 and 40 shots per cylinder, depending on the temperature.

PCP carbine stability vs CO2
Another difference with respect to CO2 is that compressed air is practically insensitive to changes in temperature. CO2 does not perform well under cold conditions, it does not expand with the same force and that translates into a bad shooting experience.

PCP carbine price vs CO2
One of the most important issues for many; It is said that the CO2 carbine is much cheaper than the PCP carbine and that is true if we strictly refer to the weapon and its accessories. As a general rule, both the PCP carbine and its accessories have a higher cost.

However, the costs derived from its use must be taken into account, since CO2 has a relatively high price and we will be using disposable CO2 bottles all our lives.

PCP vs CO2 charging system
PCP carbines can be loaded with different systems. We will not go into more details since we already talked about this topic here (Previous Link Post).

CO2 is usually loaded with a small pressurized carbon dioxide canister that fits somewhere on the carbine.

Calibers and projectiles PCP vs CO2
PCP carbines offer a wide range of caliber possibilities, you can find PCP carbines of 4.5, 5.0, 5.5, 6.35 and 7.62.

The shell market for PCP is immensely broad depending on your needs.
