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

Hatsan model 25 Supercharger breakbarrel air pistol: Part 3

Wonderful news for those who have been following the reports of the Hatsan model 25 Supercharger breakbarrel air pistol. It turns out to be accurate, which is why I reserve my final observations until I test a gun on the range.

This big pistol had a lot of strikes against it up to this point. It’s very hard to cock, the trigger-pull is too long and creepy, the gun failed to achieve its rated velocity and the breech is tight. Today, you’ll see how it did on the range, and I think most of my concerns are going by the wayside. This kind of turnaround doesn’t happen that often, as readers of this blog know only too well. We often get a sense of how well or poorly a gun is going to do in the early stages of testing. And this one looked like it was headed downhill. But after you see the results on paper, I think you’ll have to agree with me that the Hatsan Supercharger is an airgun to consider. read more

Big and powerful — Hatsan’s new model 25 breakbarrel spring-piston air pistol is different.

Let’s take a look at the velocity and power of the new Hatsan model 25 Supercharger breakbarrel air pistol. I’m testing the .22-caliber version that I selected because of the advertised power. Hatsan has not disappointed me with their power claims in the past, so I’m expecting great things from this pistol. In fact, you’ll recall that I said I wished they would turn this pistol into a carbine at the same power. Wouldn’t that be nice?

Should you use heavy pellets?
I have read a lot about why I shouldn’t use heavy pellets in a spring gun. There seem to be several schools of thought on the subject. One of them says heavy pellets do not damage a spring gun in any way. That is my position as well, and it’s based on my never having seen evidence of damage done to a gun by using heavy pellets. read more

The Ruger Mark I pellet pistol is a powerful spring-piston gun.

Before I begin, here’s a followup to yesterday’s blog on the importance of stock length. I discovered, thanks to blog reader Mike, that the No. 4 SMLE has both a long and a short stock. Apparently, when there are complaints that the rifle kicks, the stock is always a short one. I tested that at the range yesterday with a friend of mine. He had a hard-kicking Mark III and, sure enough, it has a short stock. But my No. 4 stock is at least .75 inches longer and feels like a mild 30/30 when shot.

Okay, on to today’s blog.

There’s a lot of interest in this pellet pistol, and I’ve learned a lot more while testing it. Before I did this report I read as many reviews of this Ruger Mark I pellet pistol as I could find — both on this site and on others. I discovered something while doing that. There’s a sharp difference of opinion about the gun that divides around the age and airgun experience of the person writing the review. Those who are either young or have little experience with airguns say the Ruger is hard to cock and not very accurate, but they all praise the power they think it has. But veteran airgunners who own chronographs have learned that the pistol isn’t as powerful as advertised, but it’s easy to cock (very easy for the power, if you use the cocking aid) and also relatively accurate. So, come with me today while I show you what the Ruger can do. read more

The Ruger Mark I pellet pistol is a powerful spring-piston gun.

Several readers indicated an interest in the Ruger Mark I pellet pistol, and we had one warning to watch the plastic frame for cracks. I’ll do that throughout all testing; but I can say that after today’s shooting, everything is still sound.

Dieseling
One reader commented that his pistol was the worst-dieseling airgun he had even seen. He may have said dieseling, but I think he really meant detonating, given what I see with the test gun. The test gun detonated several times at the beginning of testing, then settled down to just a diesel with every shot. But because of the type of oil or grease the factory used, there was a lot of smoke with every shot. read more
