Seneca Sumatra 2500 Review, 500cc

Sumatra 2500 air rifle is an excellent product if you’re in the market for a high-powered, clip-fed PCP aimed at varmints and pests. The detailing is excellent, and it has a classic yet modern look. You’ll want to use heavy pellets for maximum knockdown power, but the gun is accurate across the board.

Sumatra 2500 is very powerful and obnoxious. We do not recommend this as a game for the whole family, this air rifle is not family-friendly.

The Seneca Sumatra 2500 has a revolver with a rotary magazine that has six shots that give the appearance similar to an antique revolver of the west. Its barrel threads measure 10mm in diameter 1.0. The reason it is a great tool for hunting is that it has enough length to let you easily pull the pellet.

It also is equipped with an adjustable front sight with a fixed blade and an adjustable rear. The air rifle is able to attach any scope you want to choose an 11mm dovetail rail. The lever action of the air rifle lets you handle it quickly when shooting, ensuring that you can easily follow up with shots.

It has been proven that it can deliver the highest quality results on time with high performance and accuracy.

If you’re in search of a high-power air rifle to hunt varmints or targets shooting, as well as pest control then the Seneca Sumatra 2500 is unbeatable due to its distinctive traditional, yet distinct appearance.

The Sumatra 2500 air rifle has won a HAM Silver Award because it excels in quality, usability, value, and performance.

Sumatra 2500 Carbine Air Rifle Review

Speed & Accuracy

All of the regular test pellets had muzzle velocities between 1100 and 1350 feet per second. Even though the Sumatra 2500 air rifle is best known for its skill with heavy and super-heavy pellets, its accuracy actually improved when using the lightest alloy pellets. The Sumatra 2500 air rifle really shines when firing heavier pellets due to its high muzzle energies. In the tests, the H&N Baracuda Match 21.14 Grain pellets produced the highest muzzle energy at over 58 ft/lbs. This is really impressive for an air rifle of its caliber (.22), making the Sumatra a fantastic choice for the hunt.

It is important to keep in mind that Sumatra’s power adjustment wheel is set to its minimum setting for its test. This is why the muzzle velocities measured are lower than they could have been. It was found that the Sumatra 2500 air rifle’s muzzle velocity improved by around 6–7 percent when switched to high power. This is lower than I had hoped for, but given the extremely high muzzle velocities already measured, I can hardly complain.

Below, the table displays the speed and accuracy of the Sumatra 2500 Carbine rifle.

Trigger and Cocking Effort

The Sumatra 2500 air rifle I tested had a trigger pull weight of about 3 pounds, 7 ounces. The primary use for Sumatra air rifles is hunting, so this isn’t a hair trigger, but it works fine. While Sumatra’s specifications state that its trigger has a two-stage action, I was only able to identify the first stage. The release was completely foreseeable, which is a strong indication of pinpoint accuracy.

The draw weight of the trigger of the Sumatra 2500 air rifle can be adjusted in accordance with the instructions provided. I did what I always do and tested the firearm with the factory-default trigger setting.

Cocking the air rifle with an underlever is, to say the least, a bit out of the ordinary. Even though the movement is smooth, the test team noticed that repeated use of the cocking lever caused discomfort in the palm of the hand. Since Sumatra is primarily intended as a hunting air rifle, this is typically not a problem because there are so few bullets fired during hunting.

Though the initial cocking effort was greater than that required by a side lever action, for example, shooting the Sumatra proved to be easier after a few rounds. The cocking effort was estimated to be about 21 pounds. Just behind your trigger finger and up high is the manual safety. This push-across style fared well in testing.

Consistency

According to the results of the tests, the Sumatra shot accurately with a variety of pellets. The ultra-light Gamo Platinum PBA pellets were the only group to exhibit less than stellar performance (although still better than I expected). Therefore, the accuracy is outstanding in practice over a wide variety of pellets.

What I found most intriguing about the Sumatra I tested was its Standard Deviation (a measure of muzzle velocity consistency). It was never the same thing twice! Standard Deviations were recorded at a rate of 14–21 frames per second, with an average of 17.38 frames per second. Since Sumatra’s pressure isn’t regulated, each shot slows down the next one, and so on. As a result of Sumatra’s high power output, this dip between shots is more pronounced than it would be with a lower-powered unregulated PCP air rifle, such as Benjamin Marauder.

This Standard Deviation is far larger than what is typically seen in HAM’s tests, yet it appears to have had no negative impact on the accuracy (as evidenced by the test objectives).

This tested firearm also has a highly variable trigger pull weight. Again, the shooting tests clearly did not suffer from this variability in trigger pull weight because of its apparent lack of effect on the results.

Noise 

This is to be expected, as the Sumatra 2500 air rifle consumes a great deal of air with each shot, sending nearly all of the pellets tested through the muzzle at speeds above the speed of sound. On the range for this evaluation, I was definitely using earplugs.

In its basic configuration, the Sumatra lacks any kind of suppressor. The muzzle is threaded to accept a silencer attachment, which would definitely alter the findings significantly. If you go with this method, though, be careful to follow all applicable ATF regulations and laws.

Vision and Range

The Sumatra has a sturdy set of basic iron sights. There are no fiber optics, and the elevation adjustment on the rear sight must be made with a screwdriver. Most owners, however, will install a scope and use the iron sights only as a backup.

This evaluation is of the “Premium bundle,” which is the Sumatra 2500 air rifle. The Tech Force 4-12×40 AO scope and Leapers high profile rings make a great combination.

This Tech Force scope is a good match for the Sumatra 2500 air rifle in terms of size and functionality. The 12x magnification is about as much as most shooters are able to successfully exploit in the field, and the AO (Adjustable Objective) allows for excellent focusing down to 7.5 yards. The scope’s optics seemed respectable considering the cost.

For effective airgun use, I recommend a mil-dot reticle, which is included in this sight. If the shooter needs more light for low-light conditions, he or she can choose between red and green illumination for the reticle. While the front focusing ring and reticle illumination knob were hefty at first, I expect them to become more manageable with practice and in warmer climates.

Shootability

It is worth noting that the Sumatra 2500 air rifle is not light. When the scope was attached, as in the testing, the whole package weighed 10 pounds, 3 ounces. I quickly realized that a sling would be a handy tool to have on hand in the field when dealing with this load.

The Sumatra, however, provides a solid cheek weld and maintains its equilibrium when carried to the shoulder. The weight was not apparent when using it for target practice. The 4.5 rating on RateAGun backs this up, indicating that the gun is quite user-friendly.

The 6-round rotary clip improves the gun’s shooting capacity. This facilitates loading and, thus, allows for quick follow-up shots while hunting. Most of the test pellets loaded into the clip more easily while approaching it from the front, as opposed to the back, as was instructed.

As a side effect of being carried around in a pocket, pellets would frequently fall out of the clip, making it impractical to pre-load clips and bring them into the field. Since the Sumatra 2500 air rifle relies solely on friction to keep pellets in the clip, it’s possible that Eun Jin pellets will perform better in this regard.

Quality of Workmanship

The Sumatra 2500 is an air rifle that, from a distance, looks more like an “over and under” shotgun. This is because there are two air tubes located just under the barrel, an obvious design choice. This airgun certainly stands out from the pack visually. The test group’s interest in appearances was clearly piqued with time.

The metal pieces are expertly finished, with some featuring strong, deep bluing and others with glossy black paint. Castings make up the receiver, cocking lever, and trigger, with the receiver featuring deeply in-letted hunting scenes on either side.

In most areas, the woodwork was excellent, and the checkering was intricately detailed. I felt a small roughness on the buttstock’s sides, but it wasn’t too much of a problem for me. The Sumatra 2500 is a conventional air rifle in every sense of the word, with its wooden stock and metal receiver.

Price

It is the Seneca Sumatra 2500 is sold at a reasonable cost of around $700 on the market. The rings and scope make up more than $110 of that figure. At this price, you get a powerful and effective air rifle for hunting.

There is, of course, an additional charge for the air supply like the other PCP air gun.

Rick Eutsler from AirgunWeb has tested this rifle in the video below:

Pros

This PCP rifle packs a punch and is surprisingly simple to use. Experts have confirmed its remarkable accuracy with pellet-firing tests. Pellets cannot be fed twice. This weapon looks fantastic and fires six rounds every time.

Shooters and hunters that specialize in small games are the ideal target audience for the gun. The H&N field target trophy is the best pellet on the market. The Sumatra 2500 air rifle, with its.380/9mm caliber is a top pick for accurate shooting.

Cons

It’s quite noisy, and there’s no legitimate method to repair the silencers. There is also the fact that carrying a gun around is a big task. It is expensive. What’s more, this PCP rifle is not appropriate for use around children. There was only a single trigger discovered, not a double.

Conclusion

The operator’s manual is detailed and helpful, with easy-to-understand lists of parts and pictures for those who are confident enough to try to disassemble the pistol themselves. Air Venturi, Sumatra’s official US distributor, stocks all of the necessary parts and offers customer service throughout the air rifle’s 12-month warranty period. When using a Sumatra 2500 air rifle, having a full air supply is the single most crucial component.
