Gamo Whisper Fusion IGT breakbarrel air rifle: Part 4
by Tom Gaylord, a.k.a. B.B. Pelletier
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.
I’d used this mount for my report on shimming scope rings, so I did remove the scope from the rings after all. Following that report, I left in the one shim that was shown in the report. The mount Gamo included with the test rifle has four screws per cap and seems to be a good one. It’s a one-piece design that does limit the positioning of the scope, but I was able to locate it fine for my use.
The adjustable cheekpiece helped a lot. I had it adjusted up to almost the top position, and my eye lined up with the rear of the scope with no unnatural repositioning of my head.
Surprise No. 2 was the scope. I initially sight-in at 12 feet to get the shots safely on paper, and inexpensive scopes are usually very blurry this close to the target — even if they’re set on low power. This rifle comes with a very nice Gamo 3-9X40 scope that was quite clear on 3x at 12 feet. Back up to 25 yards and boost the power to 9x, and the glass remains very clear. It’s been a long time since I liked a scope that came bundled with a gun as much as this.
The Smooth Action Trigger (SAT)
Next, I must comment on Gamo’s new SAT. It’s a 2-stage unit that has a light first stage and a second stage that you can feel as you continue to pull. The trigger blade moves through stage 2 smoothly and breaks cleanly, but not with the sudden glass-rod crispness we talk about all the time. Instead, the feel is one of movement that is predictable and can be controlled. It isn’t bad — it’s just different from other triggers.
I reported in Part 2 that the trigger breaks at 3 lbs., 12 oz. That may sound high if you read about PCP triggers breaking at less than a pound, but it really isn’t that bad. The thing to do is experience it for yourself before you judge it. I find it to be manageable and not at all troublesome to the best accuracy.
The light weight of the rifle, on the other hand, does present something of a problem. This rifle is so light that even when the off hand touches the triggerguard, the rifle still has neutral balance. It floats in your hand. That makes it difficult to hold on the target because the crosshairs want to dance around. The solution is a very light artillery hold that does benefit the rifle’s accuracy, and I’ll address that in a moment.
Normally, this is where I launch into the accuracy test and start making comments about the groups. This time, I have more to say, and it isn’t just about the groups — except how they helped my understand the rifle in a diagnostic way.
JSB Exact RS
The first pellet tested was the JSB Exact RS that did so well in the 10-meter accuracy test with open sights. I knew from that test that these pellets like to be seated flush with the breech for best results.
As I shot these pellets, I saw a strange phenomenon unfold. The first 3 shots were out of the bull at 5 o’clock. Then, I relaxed very consciously and allowed the rifle to float on my off hand. The next several shots went into the black. On shot 8, I didn’t relax like I should have, and I threw 1 more shot out of the bull at 5 o’clock with the first 3. How interesting!
It was so interesting, in fact, that I shot a 14-shot group, so that 10 of the shots could be fired with me being very relaxed. When you look at where they landed, you can see that the hold was all-important to where this rifle grouped.
Now that I knew something about how the rifle performed, I figured I could do a lot better. And the very next group confirmed that.
H&N Barcuda Match
Next up were the H&N Baracuda Match pellets that shot second-best in the 10-meter accuracy test. Now that I knew how to hold the rifle, I expected to see a better group. And that’s exactly what happened.
I adjusted the scope after finishing the first group, moving it a few clicks to the left. The first Baracuda Match landed at 11 o’clock, just outside the bull. Shot No. 2 hit at 8 o’clock outside the bull. I was obviously holding the rifle too tight, so I made a conscious effort to hold it looser and shots 3 through 7 hit inside the black. Then, I tensed up again, sending shot No. 8 into the same hole as shot 2. The final 2 shots were fired with complete relaxation, and I had a respectable group inside the bull to the left of center.
This time, there were only 3 shots that missed the main group, and all of them were fired with some tension in the hold. When I relaxed, I was able to put 7 shots into 0.789 inches. I think this represents the true accuracy potential of the rifle. Total group measures 1.995 inches.
Altering the hold
Now that I understood the rifle better, I decided to move my open palm out farther so I could feel the cocking slot. Sometimes, resting the rifle this far forward is better. It certainly makes it more stable.
This time, however, there was no improvement. The group opened up, and I could see no way of controlling where the shots went. The total group measures 1.754 inches between centers, which is tighter than the previous group overall; but there’s no tighter group within this group that tells me the rifle wanted to do any better. Although this is a smaller group, I think the previous group that was shot with the off hand touching the triggerguard shows more promise. So, I went back to the other hold for the next group.
Two pellets I didn’t try were RWS Superdomes and Gamo Raptor PBA. Both had done so poorly in the 10-meter test that I felt it wasn’t worth the time to try them again at 25 yards. That’s one of the benefits of 10-meter testing — it eliminates some pellets.
But I wanted to try at least one more pellet, so I selected 7.9-grain Crosman Premier domes, simply because they’re often very accurate in spring guns.
I now knew the best hold for the rifle, so all I had to do was hold it as loosely as possible and let the pellets do the rest. Nine of the 10 pellets went into a nice group measuring 0.845 inches between centers. It was the first shot that opened it up to 1.596 inches.
I find it interesting that the early shots were always thrown wide of the main group. By the time I arrived at the third pellet, I managed to keep the wide shots to 1 in 10. That tells me something. It tells me that the Gamo Whisper Fusion IGT is a rifle that has to be learned. Once you’ve done so, I believe that your groups will be about the same size as the smaller groups seen here.
I’m going to say something that may surprise some of you. I really like this air rifle a lot. I think it is too light and the trigger takes some getting used to, but in the end this is a great budget air rifle. It really isn’t that fussy, once you learn how to hold it the right way.
For some of you, even a used Beeman R9 is too expensive. I think you may want to look at the Whisper Fusion IGT. This is a gas-spring air rifle that has not gone overboard in the power department. It has a usable trigger, and it’s reasonably quiet and accurate. No, it isn’t as accurate as an R9, nor is the SAT as nice as a Rekord trigger; but for those who want to cap their outlay for an air rifle at $260 with a scope included, I think this is the one.
