USA –  -(Ammoland.com)- We made a stalwart effort to survey the latest air gun technology at this year’s SHOT Show.  After frequenting the myriad of vendors GAMO caught our eye.

We were taken with the new GAMO Magnum Mach 1 Rifle and put ourselves on the waiting list for early delivery. We were impressed with the newly engineered break – barrel gas piston with Inert Gas Technology.

The 33mm pneumatic chamber compresses air sufficient to propel pellets over a scorching 1650 fps for .177 cal ammo. As a youth, my pump style .22 cal pellet gun barely cracked 500 fps with 10 pumps.

We took particular notice of GAMO’s Proshot ID System that makes assigning ammo to gun foolproof.

Matching the color on the gun stock gasket with that on the pellet package lid maximizes the users weapon performance:

  • Red ensures an accurate, high velocity combo best suited for small nuisance rodents and everyday recreational shooting.
  • Green emphasizes accuracy with high impact and penetration ideal for intermediate sized pests including squirrels, rabbits and competition shooting.
  • Blue designates the ultimate level of performance. We used both red and green loads for our testing and dispatching the vermin pests common to our ranch.

The exquisitely designed all-weather synthetic stock and butt shock absorber readily disperses recoil. The Custom Action Trigger System allows independent adjustment of the first and second resistance stages to less than 3 lbs.

We tested this rifle on our ranch for over 3 months.  Sighting in at 25 yards with iron sights gave consistent one inch groupings for 10 shots.  The crisp, clean, adjustable trigger pull make firing the weapon user friendly.

Precision rifling of the steel barrel made pellets pierce the air with accurate trajectory.

  • The rear notched sight accommodates windage and elevation with ease.
  • The rifle is easily operated and reliable.

I’m old school and prefer iron sights but found the AO scope, included with the rifle improved  accuracy at greater distances.

  • The 40mm focusable objective 3-9X magnification was incredibly easy to securely mount on the recoil-resistant rails.
  • The scope allowed reproducible accuracy up to 100 yards on breezy summer days.
  • The gun is solidly built and endures the routine daily abuse of ranch life.

The gun took a tumble from my 4-wheeler while in hot pursuit of a stray dog. After dislodging the debris, the gun performed flawlessly and the coated optics and shock-proof scope remained steadfast on the rails.

  • The hitting power of this rifle is awesome.

One shot humanely dispatches squirrels and rabbits. I found the weapon particularly utile for picking off rats that were attracted to our chicken coop.

We enthusiastically recommend this air rifle for target shooting and pest control. It is a pleasure to shoot and a valuable and dependable tool on the ranch.

I got my GAMO Magnum IGT Whisper last week.
But the box reads ” >24 Joules “.
I thought its 36 Joules and there are no restrictions in my country.
Did they rip me off?

Some of the above specs are still incorrect according to the gamo site (such as the cocking effort).

Ward Guffey

3″ barrel, overall length 0″, weight 88 pounds? Strange!

Aardvark

Weight: 88 pounds? Is that supposed to be 8.8? Price is pretty high too, considering I have seen a Savage Axis .223 rifle with scope for $199 for black Friday.

I wish someone would make a modern version of the old giradeli (spelling?) air rifle that Lewis and Clark carried with them when they made their quest to the Pacific. I think it held something like 40 balls and had the power to hunt large game.
