Today will be a very interesting report, in my opinion. The Gamo Whisper Fusion IGT air rifle I’m testing turns out to be a fascinating airgun in many ways. Let’s get right to the report.

Today we will look at accuracy at 25 yards with the scoped rifle. The first thing I had to do, therefore, was mount the scope. The rifle came with a scope installed in a one-piece scope mount. Its vertical scope stop pin was already correctly adjusted to fit the stop pin hole in the raised mount on top of the rifle’s spring tube. That is rare, in my experience. Normally, the scope will be installed correctly in the mount but has to be taken out of the mount to sufficiently adjust the height of the stop pin. read more

This is the first accuracy report for the .177-caliber Gamo Whisper Fusion IGT air rifle. I shot this test using the open sights at 10 meters from a rest. I did that because I usually don’t have much luck with powerful gas-spring air rifles. They tend to spray their pellets all over the place. And getting a scope mounted and stable can also be a problem, so I wanted a track record for the rifle before I got to any of that.

Smooth Action Trigger
I usually wait until the accuracy test to report on how well the trigger, which in this instance is the Smooth Action Trigger (SAT), performs. The pull weight, measured in part 2, releases at 3 lbs., 12 oz. It’s a 2-stage trigger with a second stage that needs some explanation. Instead of pausing at stage 2 and then breaking cleanly, the trigger on the test rifle — and I must assume on all SAT — pulls through stage 2. You can feel the trigger move, yet there’s no creep. The pull is — well — smooth! And it’s predictable. It’s a different sort of feel from other triggers but not different in a bad way. I don’t think anyone will need to buy an aftermarket trigger when they have a rifle with the SAT installed. Well done, Gamo! read more

Today, we’ll look at the velocity and power of the Gamo Whisper Fusion IGT air rifle. This breakbarrel rifle has a gas spring that seems to intrigue many new airgunners, so let’s talk about that first. A gas spring is a unit that uses compressed gas rather than a coiled steel mainspring to power the piston. Besides that, it’s identical to a conventional spring-piston powerplant.

What’s in a name?
There are many names for the gas spring. Some call it a gas strut, others call it a gas ram, but all these names refer to the same thing. We’re talking about a mechanical device that contains compressed air or other gas (Crosman uses nitrogen — hence Nitro Piston) to push the piston. When the gun is cocked, the piston unit is pushed backwards — making the compressed gas reservoir shorter. When the gas chamber inside the piston becomes smaller, it causes the internal pressure to rise. When the gun fires, this compressed gas pushes the piston forward, and the piston seal compresses the air in front of it. read more

Today, we’ll begin looking at the Gamo Whisper Fusion IGT breakbarrel air rifle. This rifle is offered only in .177 caliber, and I’m testing serial number 04-1C-419038-13. It has a gas spring, which Gamo calls their Inert Gas Technology, or IGT. In many ways, it reminds me of the older Whisper rifle, except the cocking is heavier. But this report will look at all the differences and new things Gamo puts on this rifle.

The rifle
There’s a lot of synthetic material on the outside of this rifle. The stock is all synthetic, as is the fluted barrel jacket and the baffled silencer on the front of the barrel (they call it a double-integrated sound moderator). My point is that if you don’t like synthetics, this isn’t the airgun for you. If you don’t mind them, though, I see a lot of potential here. read more

Kevin is responsible for this special Part 4 report on the Gamo Rocket IGT .177 breakbarrel. He pointed out that I didn’t give the rifle enough of a chance to excel in the accuracy test, and several of you agreed. Even Edith chimed in when she read Kevin’s comment. In light of the leniency I have shown the recently tested Hatsan springers, this is certainly true. I won’t change my normal way of reviewing airguns, but in this instance I can see that it makes good sense to try other pellets in this rifle. read more

I shot the Gamo Rocket IGT .177 breakbarrel air rifle to see how potentially accurate it is. This is the day many readers have been waiting for. I was even nipped in the hocks by one reader to get it done faster.

The scope
The scope on the test rifle is the 4×32 fixed-power scope that comes in the package. The optics are clear, but at 4x, the image seems small. The crosshairs are also rather coarse. So, you really have to pay attention when aiming. I would say this scope is okay to start with if you don’t want to spend more money. And since the Rocket IGT has no other sights, you’ll need an optical sight of some kind. read more

Let’s look at the power and velocity of the Gamo Rocket IGT .177 breakbarrel air rifle. You learned in Part 1 that the numbers printed on the box and gun were in disagreement with the Gamo USA website and Pyramyd Air’s site, but it turns out that 1,300 fps is the correct velocity according to an email Edith received from Gamo’s vice president of sales. Well, Edith spotted yet a third velocity claim — this time on the end flap of the box. A sticker listed the velocity as 1,000 f.p.s., with no further explanation. We’ll clear all of this up and find out just how fast this rifle really does shoot. read more
