Gamo Bone Collector Bull Whisper IGT Review


Last Updated on

Remember the “Bone Collector” movie?

When I heard that there is a gun named Bone Collector, I though that Angelina Jolie has switched her hobby from child-raising and charity to shooting sport.

Actually, she hasn’t.

In fact, the Bone Collector is designed in collaboration with Micheal Waddel and Travis “T Bone” Turner of the Bone Collector TV series. The series portraits the culture of hunters and the brotherhood of sportsmen. Therefore, it is no surprise when the gun is built on a forest theme: a special hunter green, composite stock with dark grey rubber grip insert. And the cool Bone Collector logo is prominently shown on the synthetic, high-grade stock. Gamo really knows how to catch our attention!

Gun Type

Gamo Bone Collector is a gas-piston air rifle. It gets power from Inert Gas Technology (IGT) that set it apart from ordinary spring gun. IGT guns have no spring torque and no spring fatigue even if you leave it cocked for hours. Besides, you can cock the gun and wait to take your net shot without worrying about metal spring taking a set or weakening. Gas piston rifle is robust and does not lose anything in either area, plus the gas piston is known to shoot much smoother and delivers less twang and vibration compared to springers.

This gun is break-barrel, single-shot gun so it means that you can only shoot 1 shot at a time. After that, you have to reload manually to prepare for the next round. Single-shot gun makes you discipline shooter: You have to think twice about your target and focus intensely on your shot since you have only one chance to hit the target before reloading.

The barrel is rifled with helical grooves inside the bore to make bullet spin. Spin stabilizes pellet, improves accuracy and enhances shooting range. Besides, the barrel is designed in fluted polymer jacket style. Fluting means cut out material from the cylindrical surface, hence it is lighter and dissipates heat quicker and you can enjoy long hour shooting without worrying about overheated barrel. Moreover, Gamo has installed a Bull Whisper noise dampener in this gun to cut the audible sound to the great extent. It gives you lots of benefits at hands: First, your hunting dog is less likely affected by noise. Second, it reduces recoil and muzzle blast. Third, it protects shooter hearing ability. And finally, it keep sensitive neighbor happy while plinking in the backyard and will not disturb your shooting fellows in the range.

Gamo Bone Collector comes in 2 calibers: .177 and .22 so you can choose between one of these 2 calibers what you like most.


Gamo Bone Collector Bull Whisper IGT stock

The stock is all-weather synthetic green stock. While woodstock is heavy and easily affected by moisture and temperature, synthetic stock is much lighter, doesn’t affected by outside condition and is maintenance free. Therefore, synthetic stock is extremely suitable for: shooters who don’t want to bother with stock preservation, people who live in high humidity places and hunters who go on long hunting trips and are exposed to rain, snow, etc.

This stock has dual raised cheekpiece on the left side and right side so it’s extremely useful for left-handed shooter. Besides, it has checkering on the grip and forearm to add friction to your hand when shooting, prevent slippage from shooter’s sweat and enhance accuracy. Furthermore, the stock has a pistol grip: It orients the hand in the forward, vertical way similar to the position one would take with a conventional pistol so it gives you natural and comfortable hold of the gun.

The Bone Collector’s stock features SWA – Shock Wave Absorber . Let’s talk about it for a moment. There is an entire industry centered around making after-market recoil pads. Their intents are to reduce felt recoil because constant recoil pouding to your shoulders is painful and will stop you from shooting as much as you want. While the gas piston is going to serious reduce the vibration, the SWA buttplate will stop you from feeling most of the recoil and from the remaining movement of the gun. In fact, it provides up to 74% more recoil absorption than standard buttpad. Moreover, It’s adjustable buttpad with three removable absorption cell so you can customize it according to your own need. Now you can shoot comfortably and enjoy long-hours shooting without pain on your shoulders.

With 2 types of calibers available, Gamo Bone Collector Bull Whisper has 2 corresponding types of pellets: .177 caliber uses .177 pellet and .22 caliber use .22 pellet .177 pellet is cheap: you can buy a bunch of .177 pellets for half the money for the same amount of .22 pellets. Besides, .177 is lighter and gives you higher velocity so it’s great for plinking and target shooting. On the other hands, .22 pellets are heavier, more stable on its trajectory and have more than enough knockdown power for dealing with different critters so it’s perfect choice if you want to hunt small game or get rid of unwelcome pests in your property.

The Gamo Bone Collector Bull Whisper doesn’t come with traditional open sight. No front sight, no rear sight. Instead of iron sight, Gamo put the 4×32 scope in it for more precision in shooting. 32 is a diameter of the front lens, measure in millimeter. 4 is the magnification of the scope: it means that the picture you see through the scope is 4 times bigger than the image you see without it. Having this handy scope gives you dead-on accuracy in both short range and long-range shooting.

In the past, Gamo customers have swapped out their triggers with after market ones. No need to do that anymore. The Smoothe Action Trigger (SAT), is light years better than the previous version. It’s smooth and predictable. What will that do for you? It’ll improve your grouping because heavy, unpredictable trigger is responsible for delivering large group. You’ll be amazed at how good a shot you are when you shoot the Bone Collector with the brand-new SAT trigger.

Velocity, accuracy and power

Gamo Bone Collector produces velocity up to 1300 FPS with .177 pellets and 975 FPS with .22 pellets. These are exceptionally high velocities compared to other air guns on the market and it puts this rifle belong to the magnum class in the air gun world. In addition, since the speed of sound is 1100 FPS (vary with altitude and temperature), you may hear the loud crack if you buy .177 caliber because the lightweight pellet breaks the sound barriers. If you buy .22 one then this is not an issue at all.

Chrony tests with both types of pellets give us the following results: .22 caliber produces 745 FPS with Crosman Premiere, 975 FPS with PBA and 640 FPS with 18.2 gr pellet .177 caliber delivers 926 FPS with Beeman laser 7.1 grains, 1300 FPS with PBA Gamo Raptor, 1000 FPS with Red Flame 7.9 gr, 1531 FPS and 1468 FPS with Gold PBA . As you can see, the velocities match the advertised numbers and even surpass it!

Customer review

There are lots of mixed customer reviews about this gun. In positive reviews, we see that people love its outstanding features, awesome technology, great fit and finish, quality stock, incredible accuracy and power. In negative reviews, people mostly complain about 2 things. The first is the low-quality scope: you can solve this issue simply by attached other scope of your choice on it. The second is the loud noise, and much louder than what they expect from a “whisper” gun. There are effective solutions for those problems: Make sure you clean the barrel several times to get rid of diesel in the bore, and use heavier pellet instead of lightweight one to make the gun goes subsonic and doesn’t break the sound barrier.
