The Crosman Benjamin Discovery Pre-charged Pnuematic Air Rifle. I was on my way home from a morning deer hunt when my cell phone rang, it was the project manager responsible for a new rifle being manufactured by the American airgun giant Crosman. She told me that my name had been brought up as a possible candidate to try out an innovative new airgun design Crosman was working on.

She stated that they anticipated this product would have a major impact on airgun hunting in this country, and wondered if I might like to get a pre-production gun for testing. Well of course I was interested in learning more. Therefore, the idea of Crosman basing their new PCP on the venerable design resonated with me, as the core technology is well proven.

And while the gun leveraged the established technology, optimizing it to run on high pressure air was not just a matter of slapping a high pressure air reservoir on in place of the CO2 reservoir.

A redesign of the valve, the development of the valve anchoring and installation, and a new filling port were required as well. Nor was the intent simply to build another PCP. While this type of airgun is not widely known in North America, in much of the world it is the airgun technology used by the greatest number of hunters.

But unlike much of the world, American shooters have access to low cost firearms, making the high price or European airguns less attractive to many shooters here. To gain acceptance in our market, Crosman also needed to deliver a power source that could be independent of expensive filling gear, such as compressors and high pressure air tanks. Hand pumps, which resemble nothing more than a bicycle tire pump on steroids, have been around for years and offer an attractive alternative.

But if you have a gun that needs to be charged up to psi, you may have to apply a couple hundred pumping strokes to fill the onboard reservoir.

So if the gun could be designed to work at a lower pressure but still deliver the power and shot capacity, a hand pump could be used with much less effort and free the shooter from dependency on a compressor. And from these requirements, the Benjamin Discovery was developed.

The first serious airgun for many of us was the Benjamin multi-pump air rifle, and Benjamin has always been synonymous with high production quality. When Crosman acquired this company many years ago, they wisely in my opinion decided to retain the Benjamin name as their premium brand. The Benjamin Discovery is a gun that delivers on the requirements set forth; it is based on a known technology, it is designed to yield high velocities at a relatively low fill pressure, and the price point for a package consisting of the rifle and the pump is well below what is typically paid for the gun alone.

It has also been designed to implement a feature called Dual Fuel TM technology, which permits the gun to operate on compressed air for field work or with CO2 for plinking and target practice when lower velocities are desired. To set up and get a feel for the rifle I started off on the bench. This is my normal procedure to see what pellets perform best, as airguns can be quite finicky about which projectiles yield the best all around performance.

After assessing how the gun grouped and what velocities were achieved using a variety of different pellets, I headed out squirrel, rabbit, and pest hunting. Overall Impression The Discovery is a compact rifle that weighs 5 lb 2 oz, and is 40 inches overall with a The first thing that struck me when I unpacked the shipping crate was that while the gun bears a strong resemblance to the standardthere were also some striking differences.

The stock on my test gun is a nicely figured hardwood that has a more finely shaped pistol grip than the standard The depth and width of the forestock is a bit more substantial as well, which is needed to house the onboard pressure gauge that is situated a few inches in front of the trigger guard.

The stock is finished with a buttplate made of high impact plastic, that work well enough as there is really no recoil to speak of. When personalizing this gun to make it my own, I replaced this component with a ventilated rubber buttpad to suit my own taste.

The trigger has a fairly heavy pull and is not adjustable, with a blade that is wide and has a good tactile feel. The safety is a transfer bar type that is situated in front of the trigger. The trigger guard is large and easily accommodates a gloved finger, which is important when this Californian native hunts winter squirrels in my current Midwestern home. This is the same trigger component found on theand the whole assembly is one piece and fabricated in high impact plastic.

Admittedly this is not my favorite material on a gun, sycamore options broker review the primary factor is how well it works, and well look at this later in performance testing.

Another major change with this gun is the high pressure air reservoir for onboard storage of compressed air. The Discovery stores air in a reservoir made of carbon steel DOM tubing, with a filling capacity of cc 8. The reservoir tube is capped with a male Foster quick release connector that permits easy filling of the gun, I much prefer this set up over the filling probes used in many pcp designs.

Though the recommended fill pressure is psi, the tube and valve assemblies have been hydrostatic tested to psi the tube alone to psi. Speaking of the valve, it is a new design based on existing technology. The new valve is anchored in place with three screws rather than the single anchor point used with the Five shot groups left usiing several pellets styles and weights.

That's a high shot count and good consistency benjamin discovery aftermarket stock a psi fill! The Crosman Discovery with the QB 78 PCP conversion for comparison. Both nice guns, but the compact Discovery gets my vote for an all around small game gun. Though it generates less power, it benjamin discovery aftermarket stock a much higher shot capacity, less shot to shot variance, and is much quieter. Well made and well ballanced gun, this is the lightest full sized PCP I've ever shot.

The gun is available in. The male foster fitting provides a simple filling mechanism, that is covered by a cap. The trigger is also pureCopyright idea inventionsuccess.net make money newgrounds think the modders are going to like playing with this one.

This is a very easy gun to cock and load.

I like a hunting rifle that requires very little motion or effort. Based on a couple of months of intensive use, I believe the Benji Discovery to be an excellent option for small game such as rabbit and squirrel. It is light and compact, easy to cock and load, it is accurate and powerful, and forex factory calendar ios the high shot capacity a single charge will keep you in the field for a full day of small game hunting.

I took both rabbits and squirrels out to fifty yards, and consistently achieved one shot kills. The other part of this hunting rig I really liked was the Centerpoint scope with illuminated reticle.

I found that the excellent light transmission combined with the glowing crosshairs were an asset in the low ambient light conditions encountered during early dawn and evening hunts.

Summary So if I turn a critical eye on the gun? As mentioned the plastic trigger is not my favorite aspect of the gun, but it is function that matters.

The trigger provides a good tactile feedback logiciel pour forex gratuit minimal creep and the trigger breaks crisply. I personally am happy with this trigger, it is not target quality but provides a good solid performance for a hunting rifle. I believe this will probably be the opinion of most shooters, but there are those that will want to tweak and tune it. It has a very ergonomic cocking action that is really quite nice in a hunting strategies for selling employee stock options. Easy to cock and load without a lot of motion.

The Benjamin Discovery will be an important gun for the domestic market; offering very good performance in a price effective package.

Put this in perspective; you will get a gun capable of generating over 17 fpe and placing a. This will open the world of PCP airguns to a whole new audience, which will only benefit the sport as a whole. I really think Crosman got it right with the Benjamin Discovery. The CROSMAN WEBSITE http: The pellet that produced the highest average velocity was the Beeman Laser.

The upper right panel shows the average velocities for several widely available pellets as well as a couple experimental ones. The lower right panel shows a 45 shot string using JSB Exacts, the gun hits a sweet spot after a few shots and with the exception of a couple random jumps in velocity is pretty consistent.

All of these shots would have enough power to reliably take small game. Each pellet had a sweet spot that was reached when the optimal pressure level was reached. I lifted 20 shot strings from longer shot strings with four different types of pellets to observe the shot to shot variance in the optimal range left.

These are consecutive shots, but lifted from the "sweet spot" for each pellet type. Not elegant, but it works!

Had to futz around to optimize lighting. The muzzle is 36" from chrony. Discovery Takedown Click on this link and you'll go to a page that shows the action removed from the stock. The gun is too rare a commodity for me to start ripping down further at this time.

Once I've got a couple of upcoming hunts out west cleared, I'm going in! The Discovery is a light and compact rifle that I find a pleasure backing around on a day in the woods or bunderbashing in the desert.

Light and unobrtusive, the gun can be brought quickly into play. This handeling is further enhanced by the light cocking effory.

I use two methods of charging my tanks, a carbon fiber 17 cu ft psi nd the pump pakaged with the gun. Takes bout pumps to get the gun fully charged. I flew into Las Vegas for the SHOT Show, arriving a few days early so I could get in a rabbit hunt.

My plan was to hit the open desert during the day to chase up some jackrabbits, then drive down to the thick brush along the washes bordering a desert golf course in pursuit of cottontails at dusk. The Discovery was a pleasure to carry, it is light weight and compact and after a single charge was ready for a full day of hunting. It turned out to be a hard hunt, the desert had received a lot of rain during the season and the brush was heavier than I'd ever seen it.

The rabbits were well covered and holding tight, so I ended up walking long distances glassing the area looking for signs of rabbits tucked away under the brush.

The Discovery comes easily and quickly to shoulder, and I found that I could shoot it well from any position. I took a couple of big jackrabbits the first morning out, at 35 and 50 yards respectively. Using a JSB Exact pellets, the gun yielded up power and accuracy that was capable of dropping these big desert hares cleanly. The following morning I was able to bag a couple more.

At dusk I walked along a dirt road where the cottontails would cross to get to the golf course to feed. I hid behind the scattered brush and ambushed them as they headed for the grass. All in all I found this a great little rifle to travel with. The pump disassembled for easy packing and fit into my duffle bag. I appreciated the fact that I didn't have to pump the gun over psi to get the performance required for hunting.

And I got two days of hunting in from that single charge, plus a bit of plinking to empty it before packing it away fro the trip home. I have restocked my Discovery with a C1 style stock, which is characterized by a straight wrist typical of an English shotgun. This gun is small and compact, lightweight, and it comes to the shoulder very quickly. I find it one of the most shootable guns in my collection, and it is one that I feel comfortable shooting offhand from any position.

On this trip I took it out on a cold, snowy winters day in Indiana in pursuit of fox squirrel. Wearing snow camo I was able to hunker down by a den tree and wait for the squirrels to come out and go un-noticed. The sequence below shows a squirrel dropping from a head shot, a.
