This report covers:
- The scope
- Pellet length?
- What went right?
- What remains?
Today I start testing the accuracy of the Gamo Swarm Maxxim multi-shot rifle. I decided to go straight to 25 yards, as that is the distance at which they say their scope is parallax adjusted.
The scope comes with the mount installed and all you need to do is attach it to the rifle. I found it very quick and easy to mount.
You absolutely cannot see the repeating mechanism in the scope. The image is clear. However, with a dot sight mounted at the same height the mechanism is clearly visible.
Last comment about the scope. It really is a poor optic! I adjusted the eyepiece3 to get the reticle and bullseye as clear as possible and still at 9 power I could only barely see pellet holes at 25 yards. Everything was out of focus. I resolve to mount a decent scope on the Swarm and give it another test, because this scope cost me 1/4- to 1/2-inch of group size.
Rather than walk you step-by-step through the test, I will cut to the chase and then show all the targets. The rifle I’m testing does not like to be rested directly on a sandbag. It want to have an artillery hold. I forgot to try the deer hunter (firm) hold, so I’ll have to do that in the next test.
The Predator Polymag pellets I have are the shorts, so that also did not get tested. But that is a minor thing. I don’t care how long a pellet this magazine will feed. I only care about it feeding accurate pellets. And today I found none that were.
Since I didn’t know the rifle I had to test pellets and holds. I shot 5-shot groups to save time with this. The Predator Polymag short wasn’t very accurate when the rifle rested on the bag. I put 10 into 1.341-inches at 25 yards. Yeah, that’s not too good, is it?
Ten H&N Baracuda Match with 4.50mm heads went into 2.07 inches at 25 yards when the rifle was rested directly on the sandbag. With the artillery hold described above 10 went into 1.352-inches at the same distance. So that lends credence to the artillery hold being the way to go. But there is still a lot more testing to be done.
I tried Gamo’s PBA Platinum pellets, but they cracked like a .22! I shot a 5-shot group that measured 1.049-inches. That wasn’t bad (for the Swarm) but the noise was intolerable.
Then I tried 5 Crosman Premier lites. Two of them didn’t land on the target paper and the three that did have centers that are 1.505-inches apart. My guess is the 5 went into 2.5 inches.
I then tried 5 JSB Exact RS pellets. They went into1.544-inches when the artillery hold was used and 1.332-inches when the rifle was rested on the bag.
The last pellet I tried was the JSB Exact Jumbo Heavy that weighs 10.34-grains. Don’t ask me why but I shot 10 of them with the artillery hold, even when I could see they weren’t grouping. Ten went into 2.153-inches at 25 yards.
What went right?
With all these poor groups I am telling you about, did anything in this test go well? Yes, it did. First I want to compliment that trigger. It acts like a single-stage trigger in that you can feel it moving until the release. It’s light and very easy to use.
Next I want to compliment the Swarm for shooting as smoothly as it does. It’s not harsh at all. I enjoyed shooting this rifle, except for the results downrange.
Then there is the cocking that is so easy, what a delight it is.
And finally, the magazine functioned perfectly throughout the test. And, boy, does it speed things up! If the rifle was accurate, I would be calling it a world-beater.
Well, I still have to find the best hold. That includes testing with the rifle held firmly. That is so contrary to how I normally shoot springers that I’m going to have to think about it.
I also have to mount a real scope on this rifle. My advice to dealers is replace the scopes and sell them as tent pegs.
Now, I will show you the targets.
