Seneca Sumatra 2500 500cc Reservoir Air Rifle Review

Speed And Accuracy

For any shooter or hunter, it matters a lot to have a reliable weapon when he/she is in the field.

Below, the table shows the speed and accuracy of the Sumatra 2500.

Pellet Muzzle Velocity- AverageMuzzle Energy – AverageAccuracy 
Gamo raptor platinum 9.7 grain1356.7 fps39.71 ft/lbs.Good 
H&N field target trophy green 14.66 grain1345.29 fps40.31 ft/lbs.Excellent 
RWS hobby 11.9 grain1286.53 fps43.74 ft/lbs.Excellent
Crosman premier hp 14.3 grain1232.71 fps48.26 ft/lbs.Excellent
JSB jumbo exact 14.35 grain1225.59 fps47.87 ft/lbs.Excellent
H&N field target trophy 14.66 grain1231.82 fps49.40 ft/lbs.Best tested – excellent
H&N Baracuda match 21.14 grain1110. fps57.89 ft/lbs.Excellent 

The table, as mentioned above, shows the muzzle velocity within the range of 1100 fps to 1350 fps with all standard HAM test pellets.

If we look at the Gamo Raptor platinum, we can check that the accuracy level fell a bit due to having lighter alloy pellets.

But, it was still not that bad, but even better than anticipated beforehand,

As the Seneca Sumatra 2500 air rifle is famed for its ability to deal with heavy pellets.

In a real sense, the real strength of the Seneca Sumatra 2500 air rifle is its ability to produce high muzzle energy with heavier pellets.

The HAM test had the peaked value with the H&N Barracuda match 21.14-grain pellets for the muzzle energy

See also  Diana Stormrider Review –The First Action Line from Diana

The weight of the heavy pellets increases and becomes the reason behind the muzzle energy increase.

The HAM test results show that the .25 Calibers version would be much more powerful.

As the HAM tester Doug Rogers mentioned in one of his notes: If he were searching for the best hunting air rifle, then the Seneca Sumatra 2500 would be on his list!

Note that the muzzle velocity recorded during the test was with the Seneca Sumatra 2500’s power adjustment wheel positioned at its lowest setting.

While changing the muzzle velocity to a higher value would increase the muzzle velocity by 6 to 7 percent.

AdjustableTrigger and Cocking Effort


The Seneca Sumatra 2500 is being known for its best performance among the shooters.

The trigger pull weight averaged 3 Pounds 7 ounces.

Such pressure is excellent for hunting without any disturbing.

The primary purpose of the Sumatra 2500 is to make air rifles comfortable for the hunters.

The trigger has two-stage actions, but during the test, only one single could be detected by the HAM team.

Moreover, the trigger of the air rifle is adjustable for weight pulling, and there is a manual instruction guide to give instructions for how this is to be done.

During the analysis of the trigger, the setting was left as done by the manufacturers.

If you fire many shots, the cocking lever might be a little uncomfortable on the back of your hand.

Compared to the side-lever, the cocking effort is looking hard.

Of course, if you shoot consistently, then it would become smoother or more manageable.

During the HAM test, the cocking effort for the Seneca Sumatra 2500 measured at around 21 lbs.

Along with this, the manual safety is conveniently located just behind the trigger.

It is a push that worked well for the HAM testers.

Overall, the performance of the trigger and cocking effort is satisfactory;

You can have a powerful air rifle with surety in your hands for next hunting or shooting experience.

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

Impressive Sight And Scope

The Seneca Sumatra 2500 has a set of simple iron sights.

There is no need for any screwdriver need to alter the elevation for fiber optic or the rear sight.

Many shooters may choose to fit the scope instead of any of the views; rather, they take it as a backup.

The air rifle has the “premium bundle,” which includes a Tech force-branded 4 – 12 X 40 A0 Scope and leaper high profile rings.

The Seneca Sumatra 2500 carbine air rifle with a tech force scope is well balanced in size and efficiency for better results.

It includes AO (adjustable objective) for sharp focus down to the 7.5 yards range,

And the 12 X magnification is as high as most of the hunters can exploit proficiently in the field.

Here, we can close that the optical quality of the air rifle seems good.

The air rifle has a mil-dot reticle in the scope considered to be an essential and indispensable tool for practical airgun use.

The mil-dot reticle has selectable red and green illuminations when required by the shooter if he/she has a low-light shot.

(For more on how many types of air gun sights are out there and which one is suitable for you, see this post.)

The air rifle has a front focusing ring which is somewhat best for warmer or moderate temperatures.

But it is not that suitable for the snowy time like January in upstate New York.


The Seneca Sumatra 2500, while the test revealed that it has excellent accuracy, has a wide range of pellets.

It was only Gamo platinum PBA pellets that showed the result which was not that good but better than the expectations at least.

Overall, the accuracy of the air rifle is classified as excellent over a wide range of pellets.


Measurement of the muzzle velocity consistency/standard deviation for the Sumatra 2500 tested by the HAM team.

The air rifle was consistently inconsistent!

The range for the standard deviation was between 14 to 21 fps, with an average of 17.38 fps.

The reason behind it is its unregulated design.

As soon as you fire, the next shot will be slower because the pressure is reduced for the air rifle.

Due to this reason, the upcoming shot will also be reduced.

The high power output of the air rifle means that this shot-to-shot drop is more distinguished than you would finish

With the lower-powered unregulated PCP air rifles, for instance, the Benjamin Marauder.

Shooting Ability

It is to make clear that the Seneca Sumatra 2500 air rifle is heavy.

See also  Benjamin Marauder Synthetic Stock (Gen 2) Review - The Perfect Mix of Superiority and Affordability

Seneca Sumatra weighs 10 pounds and 3 ounces when fitted with the scope.

It is the sign that the shooter must use the sling in the field.

The balance of the air rifle is pretty good on the shoulders, therefore; it gives a good cheek weld.

The Sumatra 2500 is heavy as it is weighted.

RATEAGUN has given it a score of 4.5, which means that it is easy to shoot with the air rifle.

With the six-shot rotary clip, the Sumatra 2500 is accessible in loading and gives a consistent follow-up shooting ability while hunting in the field.

Pellets of the air rifle were also tended to fall out of the clip if it carried around in a pocket for shooting.

So, it is not such an excellent decision to pre-pod clip and transports them into the field.


If you compare two rifles, Benjamin Marauder vs Seneca Sumatra PCP air rifle, you would see that Seneca Sumatra 2500 air rifle has a more abundant reservoir

This means filling it with a hand pump would take a lot of time.

The Seneca Sumatra 2500 air rifle has most of 6 to 20 consistent shots while Benjamin marauder gives you 80 shots per fill.

You can note another feature that the price of the Benjamin is around $600 and the Seneca Sumatra 2500 is for sale at $700.

During the test, the HAM team noticed that a few H&N field target trophy green pellets would not fit into this gun at all.

The Seneca Sumatra air rifle is not manufactured to use with the super light pellets.

It is good to find that the manufacturer of the Sumatra 2500 air rifle has put the features which have increased the protection level for the shooter, indeed.

If we see Benjamin marauder vs Seneca Sumatra, this is the better advantage the Sumatra 2500 air rifle has over Benjamin Marauder.

It allows the gun for “double-loaded” if the shooter loses track of the loading air rifle and firing sequence.

This safety measure makes it better than other air rifles.

Appearance And Finishing

The Sumatra 2500 air rifle is made with wood and metal.

It gives traditional construction.

In your hands, when you hold the Sumatra 2500, it is a beautiful-looking gun more than its pictures.

(For more on the in-depth comparison between synthetic and wood stock, see this post.)

The Seneca Sumatra 2500 air rifle looks like an “over and under” shotgun rather than an air gun.

giphy Seneca Sumatra 2500 500cc Review – Hunters’ Dreams Become Reality

Because it has a double air tube under the barrel, this is an unusual-looking air gun, but with an excellent appearance.

Finishing of the air rifle, Sumatra 2500 is commendable, with reliable and deep bluing for some parts and glossy and shiny black paint.

The receiver, cocking lever, and trigger are all castings, with the receiver having a deeply inserted hunting seen on either side.


We call the Seneca Sumatra 2500 carbine not indexing, as it is the long rifle with a shorter barrel.

The Seneca Sumatra is not auto-indexing but the Benjamin marauder does have the auto-indexing with ten shots repeater.

Wood finishing is generally perfect, with finely checkering.

Slight roughness was detected on the sides of the buttstock.

As a whole, the appearance and finishing of the Sumatra 2500 air rifle are tremendous and satisfying while shooting.

A not-so-quiet air rifle

The Seneca Sumatra 2500, if described for the sound, would say that it is, without any doubt, a LOUD air rifle.

If you are looking for an air rifle with silent volume so that you would not disturb the people around you, then Sumatra 2500 would not deliver this feature.

There is no silencer system in the air rifle.

As it is not a family air rifle and you will not be used in the home backyard.

The Sumatra 2500 uses a lot of air while shooting in each shot.

You may have to wear ear defenders on the range from where you will be hunting.

Without any doubt, the Seneca Sumatra 2500 is not fitted with a suppressor of any type.


Value for money

The Seneca Sumatra 2500 is sold at a reasonable price, about $700 in the market.

The scope and rings account for over $110 of that number.

At such street price, you have a potent and efficient hunting air rifle.

There is of course an additional cost for the air supply, like any other PCP air rifle.

If you take the Seneca Sumatra 2500 air rifle, it gives about the “bang of the buck” of any multi-shot PCP air rifle for high power, accuracy, and reasonable price.

There is a manual operating guide for you to get information while buying the Sumatra 2500 air rifle.

The US distributor, Air Venturi, has the full range of all the parts available for the Seneca Sumatra 2500

And provides support for the 12-month warranty on the air rifle.

Manufacturer’s Claim Analysis

The manufacturers claimed that the muzzle velocity of the Seneca Sumatra2500 air rifle in .22 Calibers is 1100 fps.

But while shooting was done during the HAM test, the value exceeded the 1350 fps for 21.14 grain.

The muzzle velocity of the air rifle is extremely conservative, as the test results showed.

As the manufacturers claimed the accuracy of the Seneca Sumatra 2500 air rifle is very likely to achieve by a good shot on an average, calm day.

The HAM team tested the air rifle with a wide range of pellets in 10 shot groups.

Even the makers have not claimed on that level the air rifle Sumatra 2500 works.

The air rifle is an accurate air rifle with great effort and energy.

One more thing, the makers have claimed for the two-stage trigger.

But, when the HAM test was conducted, it was astonishing to see that the team only found the single-stage trigger

And gave the remarks for the trigger being ok and not that impressive.

Customers Reviews

The reviews of the customers for the Seneca Sumatra 2500 air rifle are mostly positive,

And users are encouraging people to buy the air rifle for the reason that it is precise enormous hitting power with excellent finishing and appearance.

In the same way, the six-shot cylinder magazine is also appreciated.

The look or appearance of the air rifle is of high quality.

It has a lot of power in higher settings as well.

Customers claim that the air rifle is most accurate when adjusted between 800 and 950 fps depending on the weight you are shooting at.

Many customers own the .25 Calibers on a set of medium power and at a distance of 50 yards.

Customers are satisfied with the power of the gun as the comments show that the results are far better than their expectations.

Shooters after the use also like the looks of the air rifle as the Seneca Sumatra 2500 air rifle is made with hardwood

Which gives a traditional look to the air rifle.

After that, when it is used, it looks great in your hands.

There are many things that customers have recommended to change.

The trigger is not two stages, and the adjustment is not that satisfactory.

Among customers, the trigger is not being loved.

The magazine does not have the capability of preloading and carrying in your pocket.

Another suggestion from the customers is for the loudness of the air rifle.

The Sumatra 2500 is so loud that it disturbs the fun during the shooting.

The main focus of the customers is on the noise level as they have experienced.

I would not say that you can avoid the noise; instead, you have to bear if you are an accurate shooter

And wish to have an air rifle full of power and accuracy.

In summation, the Seneca Sumatra air rifle is the rifle for the real shooters.

It is the most powerful air rifle, but it is not the rifle for family use.

We can say that it is not a family-friendly air rifle.

You cannot give it to any untrained beginner; instead, the Seneca Sumatra 2500 is for the trained or professional hunter.

From an appearance point of view, the quality of the wood is also commendable! This is one of the best PCP air guns on the market today!
