GAMO Whisper Fusion Pro Airgun Review

    This post was written by Dr. Jim & Mary Clary.

    GAMO has been designing and building high powered air rifles for adults for over 50 years.  They have their own factory located in Spain where the air rifles are made.  In that way, they can control the integrity and quality of all critical parts.  Their rigorous inspection system and ongoing testing, results in a quality product that is unmatched in its price range.  And, if there is a problem with one of their rifles, their service center has a rapid turn-around-time.  I know that for a fact, as I had some work done on the stock of my Bone Collector.  Including transit time, it was under three weeks…. out and back.  For the record, the service center folks did not know we were writers and testers.  As far as they knew, I was just another GAMO customer.  That tells me that they really do care.

    After seeing the Whisper Fusion Pro at the 2013 SHOT Show, I decided to order one.  If it performed as advertised, it would mean that GAMO once again “raised the bar” on airgun technology. The Fusion Pro arrived two weeks later.  It was just as I remembered, a very good looking gun that felt right when you put it to your shoulder.  The eight pound weight of the Fusion Pro is comparable to many hunting rifles, which makes it easier to hold on target than lightweight airguns.

    Although the gun only fires 100 feet per second faster than the well known GAMO Bone Collector, 1400 fps compared to 1300 fps, the devastating effect on our targets was demonstrably greater.  I know that doesn’t sound logical, but it is a fact.  Using GAMO PBA Platinum pellets in both guns… hit a can with the “slower” 1300 fps Bone Collector and the can is knocked over.  Hit a can with the 1400 fps Fusion Pro and the can hardly moves; yet, the pellet leaves a 3/8″ hole in the can.  I can just imagine what it will do to small game…. a guaranteed humane kill.

    The only drawback for me was the cocking effort… the Bone Collector requires 32 lbs to cock, while the Fusion requires a hefty 41 lbs.  The extra poundage is due to the stronger spring and additional baffling to quiet the Fusion Pro.  The Bone Collector is very quiet for a high velocity airgun, but the Fusion is even quieter.  That makes for an excellent squirrel gun next fall.

    The open sights are larger than found on most rifles making them exceptionally easy to use.  The elevation and windage wheel adjustments on the rear sight makes fine-tuning during sight-in simple and quick.  The neon green and red fiber optics in the open sights make holding on target very easy.  You don’t find these extras on many other airguns.

    The optics on the 3x9x40 GAMO scope are crystal clear and is comparable to many high end centerfire riflescopes.   In fact, in our previous article on the Bone Collector (which I really liked) I stated that it would be nice if GAMO would put a better scope on future guns.  They did just that with the Fusion Pro.  This scope is definitely first class, far better than any low-end scope we have seen that are usually sold for airguns and .22 caliber rifles.  It even comes with a parallax setting for 50 yards.  And, the scope rings (included) are already fixed on the scope to insure proper mounting on the Fusion.

    We tested the Fusion Pro with three different GAMO pellets:  Red Fire, Lethal and PBA Platinum.

    We set up our targets and used the Caldwell DeadShot FieldPod for stability during the shoot.  The target distance was 25 yards, with a few pellets fired at 50 yards to test the effect of the pellets on cans.  The results speak for themselves.  Each of the three pellets produced very accurate results as illustrated by the following targets.  Since our Chrony does not accurately measure the velocity of pellets, we could not record the velocity of the pellets for comparison.  However, if the accuracy means anything, the velocity was comparable for all three pellets.

    GAMO made a giant leap forward with this gun.  Instead of using the grooves on the receiver for scope ring attachment, which is common on most airguns and 22 caliber rifles, they installed a raised rail (standard).  When the scope is attached, it is solid and cannot slip backward or forward along the rail, which is not an uncommon problem with scopes mounted on grooved receivers.

    The trigger is crisp, with no creep and makes accurate shooting easy.  The 3.74 lb “out of the box” pull was easily adjusted down to 3 lbs for increased accuracy.   I would still like to see a metal trigger blade, as opposed to the plastic blade that is standard on these guns; however, that is just my personal opinion.  The SAT™ functions just fine, I am just old-fashioned and prefer metal or high end polymer materials whenever possible.

    If anyone has any questions on the Whisper Pro Fusion, they can feel free to contact Fedor Palacios, the Marketing Communications Manager for GAMO.  I have had several emails with him.  Fedor is most responsive and more than willing to help with any problem or question.  In this day and age of impersonal corporations, it was really nice to find out that GAMO has Fedor who stands ready to field all questions.

    In our opinion, this is absolutely the best air rifle that GAMO has ever made.  It costs a bit more, but is well worth the price.  It should provide years of service for both the target shooter, occasional plinker and avid hunter.  I love my Bone Collector, but I gave it to Jim, as I am keeping the Whisper Fusion Pro for myself.  GAMO has definitely “raised the bar” on airguns with this rifle.
