Gamo Rocket IGT breakbarrel .177 air rifle: Part 3
by B.B. Pelletier
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 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.
Starting the test
I decided to use the same four pellets that were used in the velocity test. The distance was 25 yards and all shooting was done indoors, so weather wasn’t a problem. The first pellet tested was the JSB Exact 10.3-grain dome that delivered velocity in the low 800s. The group started very well. Around shot five, it had opened to twice its size. By the end of the session, it was double that. The 10-shot group measured 1.074 inches between the centers of the two widest shots.
It’s always best to evaluate the trigger when shooting for accuracy because you notice every little nuance while trying to hold the reticle still on the target. I now discovered that stage two of the new Gamo trigger has a long perceptible movement. I won’t call it a creepy trigger, but you certainly do feel it move as the sear gradually disengages.
So, my evaluation of the trigger changes from great to just good. It’s certainly the best trigger Gamo has ever fielded; but at the same time, it’s no Rekord.
Back to the test
I felt that JSB pellets were teasing me, and they really wanted to shoot better, so I would come back to them, but next came RWS Hobby pellets. Three shots went into three inches and they were through. Hobbys are not the right pellet for the Rocket IGT.
Next up was our new friend, the H&N Baracuda Green. I expected them to shock me with their accuracy after all the recent success we have seen. But the first group wasn’t that good. It measures 1.141 inches between centers, and you will see that it is more vertical than horizontal.
Since I’d now shot two vertical groups, I decided to try a differtent hold. Instead of placing my off hand at the rear of the forearm where I could feel the triggerguard, I moved it forward under the cocking slot. Then, I shot another group of H&N Baracuda Greens. This group measures the same 1.141 inches as the first group, but it’s even more vertical than the first.
At this point, I stopped shooting and checked all the stock screws. All were loose, and the two in the forearm had to be tightened quite a lot. When I returned to the bench, the point of impact had changed — and H&N Baracudas no longer grouped very well. Four shots went into 1.50 inches, and I just stopped shooting.
It isn’t supposed to work like that. Tightening the stock screws is supposed to give you the best groups the rifle is capable of; but with the Rocket IGT, that did not happen — at least not with Baracuda Greens. However, something told me to try the JSB pellet again, so that’s what I did.
The next group of JSB Exacts was shot with my off hand against the triggerguard and the stock screws tight. This time, there was a lot less walking of the pellets, and I ended up with a fairly good group of 10. It measures 1.025 inches between centers and is much rounder than any of the earlier groups. This is the best group shot during this test and is probably a good representation of what this rifle is capable of.
Gamo PBA pellets
I couldn’t do this test without giving Gamo’s PBA Platinum pellet that came with the gun a try. So I shot two of them. They cracked like a .22 long rifle in the house and landed seven inches apart. That ended the test!
What do I think about the Gamo Rocket IGT? Well, it has many good things going for it. Light weight. Easy cocking and a good trigger are the main ones. The power is also reasonable.
On the minus side, the accuracy I saw was mediocre at best. But I only tried four pellets in the rifle. Who’s to say there isn’t a good pellet that would make this rifle shine? It only needs one.
