Last Updated on

The Gamo Big Cat 1250 air rifle might be intimidating at first. “Big Cat” implies that there might be something nasty about this gun. After reviewing this gun, though, I can confidently say that this air gun will take you to the next, or should I say, supersonic level!

Gamo Big Cat 1250’s Gun type

gamo big cat 1250 | gamo big cat 1250 review

The Gamo Big Cat 1250 is a spring powered air rifle. For each shot, the spring inside is compressed by the cocking action. When you pull the trigger, the spring decompresses, causing the piston to move forward. The piston in turn makes the pellet go down range due to propellant force from compressed air. All of this happens in the fraction of a second. With this springer, you don’t need to pay for things like CO2 cartridges or pumping equipment like other air rifles.

The barrel of this air gun is a rifled barrel (or spiral barrel), more on that in this post.

Furthermore, this barrel is fluted. Fluting removes material from the cylindrical surface and creating grooves. This type of barrel is more lightweight compared to non-fluted and it dissipates heat quicker as the air inside the barrel reaches the surface. This unique feature of the Gamo Big Cat 1250 allows you to shoot for long hours without worrying about an overheated barrel.

The Gamo Big Cat 1250 also uses a break barrel, single-cocking system. In order to cock it, you have to slap the muzzle firmly while holding your air gun upward. You can then insert the pellet (with pellet’s nose lying forward and pellet’s skirt facing you). Once the pellet is inserted, swing the muzzle back to its original position. 


The Gamo Big Cat 1250 features black, all-weather synthetic stock . For more on the in-depth comparison between synthetic and wood stock, see this post.

It also uses a non-slip texture design in the grip and forearm, which adds more stability to your arm when shooting. The Gamo Big Cat 1250 has the twin cheek pad, a convenient feature for either the left-handed or right-handed shooter. It also comes with a ventilated rubber recoil pad and helps absorb recoil up to 74%.

The Gamo Big Cat 1250 has the twin cheek pad, convenient for both left-handed and right-handed shooters. There is no difference whether you shoot with your left hand or right hand. This air rifle also has a ventilated rubber recoil pad, provides a pleasant feeling for your arm, and helps absorb recoil up to 74%. Without the recoil pad, you might hurt a little since the kickback level for a spring air gun is quite high.


The recommended pellet for the Gamo Big Cat 1250 is the 0.177 PBA platinum pellet. A PBA pellet is short for a performance ballistic alloy pellet. It is domed and weighs 4.7 grains. As the name implies, it is made from alloy (a material that is made from two or more metallic elements), lead-free and environmentally friendly, so you can shoot thousands of rounds in your property and won’t add dangerous dangerous chemicals to the land. The PBA pellet is 50% harder and 30% more accurate than a conventional lead pellet and therefore has more knockdown power and more stability in its trajectory. PBA ammo is great for target shooting, plinking, small hunting, and small and large pest control.

So, what’s exactly a PBA, you ask? Well, PBA is short for Performance Ballistic Alloy pellet. It’s domed and weighs 4.7 grains. As the name implies, it is made from alloy (material made from combining 2 or more metallic elements), lead-free and environmental friendly so you can shoot thousands of rounds in your property without concern about the threat of dangerous chemicals. The PBA pellet is 50% harder and 30 % more accurate than a conventional lead pellet. Hence, it has more knockdown power, is more stable when it travels toward the target, and has more ability to kill varmints quick and clean with only one shot. You can use PBA ammo for target shooting, plinking, small hunting, and small and large pest control.

Additionally, though, while PBA pellets generate more velocity and are more accurate than other lead pellets, it is a little pricier. For $15, you only can buy 100 rounds. If you don’t want to pay much for your ammo, you can purchase alternative alternative pellets such as the Crosman destroyer, the Crosman Primiere (hollow or domed work), Gamo Raptor, Gamo pro magnum, or Gamo rocket.

Fifty rounds come with your purchase. This is particularly useful since it can be hard to find the PBAs. Make sure you look through the box carefully as these pellets are somewhat hidden in the packaging.

Velocity, penetration power and accuracy

While the accuracy of this gun might vary based on your skill level, the velocity and power of the Big Cat is no joke. 

The velocity of the Gamo Big Cat 1250 is 1,250 feet per second (FPS) with PBA platinum and 1,000 FPS with lead pellets. Since the speed of sound is around 1,100 FPS this air gun has achieved supersonic velocity and therefore belongs in the magnum class of air rifles. This is definitely not a toy and must be handled with extreme care.

With 4.7 grains PBA and 1,250 FPS, it gun has more than 16 foot-pounds of muzzle energy (or FPE; i.e., the kinetic energy of the bullet when it leaves the muzzle). With 5.4 grains pellets and 1,000 FPS, FPE is 12. With 7.9 grains lead pellets and 1,000 FPS, this gun has 17.6 FPE. It’s obvious that the Gamo Big Cat 1250 can take down squirrels, starling, opossum, raccoon and other small varmints in one clean shot since the FPE recommended to deal with these animals is less than 15 FPE.

Lastly, with the heavy duty power and supersonic velocity, this gun can shoot up to 100 yards. Most customers have no problem getting close shooting groups up to 40 yards or taking care of varmints in 40 yards or less. Some even can shoot an apple at the distance of 60 yards.

The Gamo Big Cat 1250 is equipped with 4x x 32mm rifle scope including rings. This scope has crosshair so you can see clearer, aim better and shoot more precise at long distances.

While researching the product, I found two opposing customer viewpoints around this scope. Some found it accurate while others hated the scope. Generally speaking, if you follow the user manual, then it seems that this scope would be a great piece for this gun. However, if you aren’t strictly following the user manual then you may have a hard time zeroing in on your target. If you require a more sophisticated scope for extremely long range shooting (up to 100 yards), and want to utilize the maximum potential of this magnum springer, then it would make more sense to switch to a more powerful scope. 


The Gamo Big Cat 1250 only has one rifle scope as an accessory. If you want more shooting accessories, Gamo has plenty of choices for you to choose from such as cleaning oil, gun bag, gun case, and paper targets.


The Gamo Big Cat 1250 is very loud when using the PBA pellet, but can be much quieter with other lead pellets. This is because the PBA pellets travel at 1250 FPS, which is higher than the speed of sound. There will be a large crack when you shoot this gun. If you fire using other lead pellets, then the gun will be much quieter as they sit in the subsonic range. 

If you live in an isolated area, you may want to buy some ear protection while shooting with PBA. However, if you live in a more populated region and don’t want your neighbors to report gunshots, you can shoot PBAs at a sound-proof place like a range, your basement or garage, or you can also purchase other types of 0.177 lead pellets with lower speed. 

Shooting range and intended use

This air gun is intended for target shooting, small game hunting, and small and large pest control. The effective shooting range for this air rifle and 4 x 32 scope is up to 40 yards. If you want to shoot at a range longer than 40 yards, you may want to equip another scope with better magnification ability.

Gamo Big Cat 1250 Price

The price for Gamo Big Cat 1250 is very affordable at around $100. It is well worth it to enjoy the supersonic velocity and magnum power of this awesome springer.

There are a couple of different listings on online sites with different prices but the listing I found with the lowest price is even cheaper than the price on manufacturer’s site or the prices on other e-commerce sites like PyramydAir, Walmart, AirgunDepot.
