GAMO Swarm Maxxim Air Rifle – Gun Review

USA –  -(Ammoland.com)- The GAMO Swarm Maxxim Air gun is a rifle for serious airgun shooters and incorporates the newest innovation on the market:

A 10-round magazine, called 10X Quick-Shot, that reloads the gun each time it is cocked. It took years for GAMO to perfect this patent pending device and it works flawlessly. The weight and balance are perfect, making it easy to get on target for a shot.

The following are some of the unique features of the Swarm Maxxim that we liked:
​
First up is the Recoil Reducing Rail system (RRR). Most airguns have grooves for mounting the scope rings, similar to a lot of conventional rimfire firearms. A common problem has been the inability to tighten the rings down to prevent slipping due to the intense recoil of high-power airguns. That problem has been eliminated with a very secure 5-screw mounted rail (RRR). This “picatinny style” rail consists of two pieces that are separated by polymer struts. The unique design of this patent-pending design virtually eliminates the recoil-stress on the internal components of the riflescope.
​
And, speaking of recoil, the Shock Wave Absorber (SWA) recoil pad is just as effective as the Limbsaver pads on our high-power hunting rifles. There are very few airguns that bother putting effective recoil pads on their guns. Most simply use a piece of molded rubber to cover the butt stock and call it a “recoil pad.”

GAMO’s Whisper sound suppression technology was designed to quiet down their spring and gas piston powered airguns and mitigate the “twang.” That technology was also applied in the Swarm Maxxim.
​
The conventional spring power plant found on GAMO (and other) airguns has been replaced with a pneumatic cylinder. This is called the Inert Gas Cylinder (Inert Gas Technology – IGT). When cocked, it compresses the air to deliver a consistent pressure which propels a .177 PBA pellet to a velocity up to 1,300 fps and a .22 PBA pellet to a velocity up to 975 fps. Our Swarm is the .22 caliber version and we confirmed a velocity of 950 +/- 20 fps after multiple tests with our Caldwell Premium Chronograph.
​
The Custom Action Trigger (CAT) allows the shooter to independently adjust both the first and second stage of the trigger. It is great, and out of the box, the trigger pull was set at 3.2 lbs.

All that remained for us to do was to shoot the Swarm for accuracy. ​After “dialing in” the rifle at 25 yards, we shot for accuracy using the Caldwell Lead Sled DFT 2 for stability. To state that this gun is a “tack driver” would be an understatement. We consistently shot groups of ten pellets that measured under one inch in diameter (center to center).

• In a previous article, we mentioned the GAMO ProShot ID System. This system was devised by GAMO and is unique in the airgun field. As such, we felt it was worth discussing again. It labels the best application for each rifle in their line AND it matches the various GAMO pellets to those applications. The system involves three color codings: Red, Green & Blue.
  ​
  PEST CONTROL & RECREATION : Provides accuracy and high velocity – ideal for nuisance animals such as mice, rats, birds, and snakes. Also perfect for recreational shooting.
  ​
  HUNTING : Delivers accuracy with higher energy downrange for ultimate impact and penetration — ideal for small game such as rabbits, squirrels, Raccoons, and crows.
• TARGET & COMPETITION : Offers the ultimate in accuracy and consistent performance — ideal for both training and competitive shooting.

The ProShot ID System by no means indicates that a particular gun can’t be used for one of the other applications. It is a recommendation to help the consumer decide which gun is right for them. And, since the GAMO pellets are also color-banded, we no longer have to guess which pellet is best for our shooting. We just look for the appropriate color marking on the package and pay the clerk at checkout.
​
About the only thing that GAMO can’t do for you is shoot the gun.
