Benjamin Varmint Powerpack .22 Review

Benjamin Varmint Powerpack air rifle

Last Updated on

The Benjamin Varmint .22 air rifle has the word “varmint” in its name, implying that the manufacturer’s vision was to bring back peace into your property by making a gun that could eliminate those pesky and sneaky critters with ease.

But is it a great gun for the job? Read more to find out.

Gun Type

The Benjamin Varmint Powerpack air rifle is powered by nitro piston technology. A nitro piston gun (or gas piston gun) works the same as the spring gun but it has a nitrogen-filled cylinder instead of a coiled spring. The air in the cylinder is already compressed and you apply more pressure to it when you cock the gun. The pressurized air is kept under tension until you pull the trigger. When you fire, the pellet is propelled downrange through the barrel due to the driving force from compressed air. Nitro piston rifle is lighter and lasts longer than a spring gun. Besides, it produces less recoil and is easier to cock. Nitro piston has taken the air world by   storm because it’s a proven technology that takes the shooting experience to a whole new level. If you like smoother-shooting guns that don’t have spring fatigue because you left the gun cocked while waiting for the next critter to cross your path, then a nitro piston rifle is your gun of choice. Read more about it in this post to see how nitro piston technology can make your gun sport even more awesome.

The barrel has a caliber (the diameter of the bore, measured in inches) of .177 (4.5 millimeter). It has helical grooves inside the bore to make the bullet spin. Spin stabilizes pellets, improving accuracy and enhancing shooting range.

This gun is a single shot, break barrel air rifle so you can only shoot one shot at a time. After your first shot, you have to break the barrel to prepare for the second shot. Single-shot guns makes you a better shooter as you have to make your first shot count.  Besides, it gives you control over your ammunition, and you can find out what pellet works best with your gun in the shortest amount of time.

The barrel is a shrouded bull barrel, which means that it has a jacket enclosing the barrel and containing the violent release of compressed air from the muzzle. It lets the pellet escape but forces the air to use up as much of its energy before it leaves the shroud, thus reducing the noise.

The stock is synthetic . Unlike wood stock which is heavy and easily affected by moisture and temperature, synthetic stock is lighter and performs reliably no matter how cold, hot, humid or dry it is outside. Synthetic stock is best for hunters hunting in the field with different kinds of weather or for shooters who don’t want to bother with stock preservation.

This stock has comfortable dual raised cheek pieces on both the left and right side of the gun. Raised cheek pieces are designed to provide you with firm control during the shot cycle. Moreover, this gun has a rubber buttpad that helps reduce recoil. Also, it has a textured grip and forearm that adds friction to your hands when shooting, prevent slippage from shooter’s sweat, and increase stability in aiming.


The Benjamin Varmint .22 Powerpack uses .22 pellet as its only source of ammunition. While .177 is lighter and likely to be affected by wind on long-range shooting, .22 is heavier and more stable in its trajectory. Moreover, .22 has a larger diameter and delivers more knockdown energy required in hunting situations, so .22 is a favorite choice of pest eliminator and small game hunter.

Cocking and loading

Cocking the gun: First, put the gun ON SAFE, hold the gun by your side, then firmly tap the muzzle end to expose the breech. Let the gun rest on your upper thigh and grasp the muzzle end. Continue to pull the barrel down to its limitation to perform cocking action.

Loading the pellet: With the breech opened after cocking, put the pellet (with the pellet’s nose lying forward) into the breech. Then pull the barrel up to its original position until it locks and you are ready to fire.

As you can see, the operation of this break barrel rifle is easy and straightforward. So you will learn how to handle this gun in just a few hours.

Velocity, accuracy and power

The 1200 FPS Amazon description is a misprint; this gun actually produces up to 950 FPS with alloy pellets, a high velocity compared to other .22 on the market. The high speed combined with a large .22 caliber make lethal killing power, so a successful day of pest control is within your reach.

For Crosman Varmint .22, various shooting tests have been conducted by different shooters with positive results. The common shooting groups are: /14” at 20 yards, 1” at 30 meters, 1 1/2″ at 30 meters, 1/4″ at 15 yards, 1.5” at 40 yards, 1/4″ 25 yards, dime size at 30 yards and dime sized at 70 yards. This is an extremely accurate gun up to 70 yards.

The accuracy is great, but how about power? Let’s take a closer look: at 33 yards, this gun can shoot through 7/16” plywood; it also damage a patio block at 10 yards. And with 13.12 gr Hatsan Vortex pellet, it shoots right through a deer skull at 35 yards. What a powerhouse gun – something you can trust in your quest to bring peace and beauty back to your backyards.


Benjamin Varmint Powerpack .22 scope

This gun doesn’t have a traditional iron sight: no front sight, no rear sight. But this gun does come with 3-9×32 scope: 32 is the diameter of the front lens, measured in millimeters. 3-9 is the magnification ability of the scope: it means that this scope makes the picture 3 to 4 times bigger than the image you see when you see without it. As if the variable scope is not enough for successful shooting day ,Crosman has installed a lot of optics including a Red Class III fast acquisition laser with push on/off or remote tape switch, 90-lumen flashlight and mounts (the flashlight has a red flip-up filter). This optic combo lets you hunt anytime, anywhere, from day to night with great visibility.

The rail is manufactured in the Picatinny style. A Picatinny rail is almost identical to the weaver rail, except it has a series of ridges located at precise intervals along the rail. This type of rail gives you lots of benefits: You have more mounting options and you can swap the scope from one gun to another and use different scope in one air rifle as well. And yes, no more worrying about tube length, eye relief, etc since you can place the scope ring at any point you want.

This air rifle will perform reliably and hit hard, and do so quieter than what you’d expect from a similar magnum spring gun. It’s the perfect gun for shooters who are busy all day and only have free time at night to take care of annoying varmints in their property.
