I’m still in New York for another few days and pulled this article from Airgun Revue #1 because blog reader iyonk asked for a write-up on the Sharp Ace. The article was originally published in 1997.
Airgunners are sharply divided about which segment of the hobby they’re interested in. Some are spring-piston shooters, some only like CO2, while others shoot only precharged guns. There’s also a fiercely dedicated group of airgunners who view the multi-pump pneumatic air rifle as the only gun worthy of the title.
Within this small community, there are further subdivisions centered around the various American brand names Benjamin, Crosman and Sheridan. They argue such points as whether or not the Crosman Town and Country was a better all-around rifle than the famous Sheridan Model A Supergrade (it wasn’t), and whether or not a front-pump Benjamin has more power potential than a scissors-linkage underlever. And the boys who had Benjamin pumps in their youth will remain brand-loyal to their graves!
But they all stop talking whenever the name Sharp Ace is brought up. For, with just its limited exposure in the US marketplace, this Japanese pneumatic has built up such a legend that it’s hard to tell fact from fantasy any more. So, the focus of this article is on the .22 caliber Sharp Ace Hunter. Is it the Sheridan of the Orient?
The Sharp Ace comes in either the Hunter trim or as a Target model. They’re very different rifles. Aces also come with relief valves, to limit their total pressure for the power-restricted UK market, or with unrestricted for U.S. specifications. The subject of this article is an unrestricted gun. It was originally sold by Beeman Precision Airguns in the early 1980s, when that company flirted briefly with some Sharp models, plus Benjamins and Sheridans, in their product lineup. Sales must have been slow, for the Sharp guns have always been priced way above their U.S. counterparts. Today, the Ace Hunter costs in excess of $300.
The rifle is almost all steel (it has a plastic trigger) with a tasteful beech sporter stock. It weighs about 6.3 lbs., which is about one pound more than the Sheridan Blue Streak of the same era (early 1980s). But the deeper stock and longer barrel of the Ace make it look and feel like a much larger air rifle. In fact, when you compare it directly to the Sheridan, it makes the American gun look positively diminutive, even though the Ace is only a few inches longer overall.
The sights are a crudely adjustable rear aperture and a cheap, hooded front post that doesn’t have replaceable elements. Here, the Japanese could have learned a lesson from Daisy, who manages to put fine adjustable sights on guns costing less than one-third the price. But, when compared with the Sheridan Blue Streak, the Sharp comes out on top. The Blue Streak can have a Williams aperture fitted as an option, in which case it moves ahead, but the simple (and goofy taffy-pull) sights it comes with puts the rifle from Racine (now East Bloomfield, NY) squarely in the back seat.
The Sharp loses some ground in the trigger department. This is due to the designer’s choice of air valves. Where the Sheridan has a traditional knock-open or striker-type valve, in which a spring-loaded weight (called a hammer) forces the valve stem open, Sharp chose to go with a blow-off valve system. With this system, there’s no requirement to cock the rifle, because the act of pressurizing the reservoir is all that’s required. The trigger doesn’t release a spring-loaded weight–it frees the rifle’s valve to open violently and release all the pressurized air stored inside. Crosman used this type of trigger in their 140 and 1400 rifles. When they worked, they were adequate, although the trigger effort grows with each additional pump of air in the reservoir. Crosman designed some ingenious adjustments into their final 1400 triggers, which made them quite livable; but they were never anything special. The Sharp is in the same boat. There are adjusting screws, but the net effect isn’t that noticable.
The trigger on the Ace Hunter is creepy. Besides being made of plastic, the performance of this trigger is remarkably mediocre. For this article, I compared it to an inexpensive Crosman 1400 Pumpmaster; and although the Sharp was better, it wasn’t $225 better! The Sheridan trigger was crisper than the Sharp, although the latter was considerably lighter. Of course, the current gun being sold as the Sheridan Blue Streak has a completely redesigned trigger, which breaks at over 8 lbs. The Sheridan I’m using for this comparison is the classic Blue Streak with the rocker-type safety, manufactured between 1964 and 1990.
When I first pumped the Sharp, I was put off by the loud click the wood forearm made when it slapped the metal reservoir. Then, I discovered that it wasn’t necessary to bottom the pump handle against the gun as it is with almost every other pneumatic. Pumping became much easier. Both the Sheridan and the Crosman 1400 are smoother to pump than the Ace, but not much. The Sheridan also has a rubber bumper to silence the pump handle noise, making this another feature we must deduct from the Sharp’s design.
Another quirk you’ll notice when pumping the rifle is a bobwhite whistle when the internal chamber opens to accept each stroke of air. It’s not annoying, but I’ve seen this happen only in Sharp guns.
In the area of fit and finish, the big Sharp comes out second to the Sheridan. The bluing of the steel parts is even, but underneath they’re finished only to an average degree of smoothness. Polishing with Flitz metal paste can bring things up to the German Weihrauch level of finish, but the gun certainly does not start out at that level.
The wood stock is well-shaped and finished, and great credit must be given for the tight complex join between the pump handle and the buttstock. Alas, all this fine woodwork is rendered in beech–an adequate, but ho-hum wood, at best.
And the steel barrel, while it’s a more traditional metal for firearms and spring airguns, is a poor choice for pneumatics. The cooling effect that accompanies every shot promotes condensation in the bore, which results in rust unless measures are taken. We lubricate all our pellets for pneumatics and CO2 guns with FP-10. That way, they leave a thin coat of oil in the bore and rust doesn’t get started.
The Sheridan metal parts are made of brass and painted, a feature that will turn off many airgunners. But the finish on my 18-year-old Blue Streak looks as fresh as the blued 13-year-old Sharp Ace, which was virtually unused when I got it. So, both guns are durable, with the Sheridan having the preferred metal in the barrel. The Sheridan stock is American black walnut, a wood that leaves beech in the dust. To find walnut on an $80 gun (the price when new in 1978) is remarkable.
Power and accuracy have always been the strong suits of the Sharp Ace, and our test rifle did not disappoint in those categories. Five 14.3-grain Crosman Premier pellets went into a group at 10 meters that measures 0.096″ center-to-center. That was with four strokes of the pump handle. The instructions say eight pumps are maximum, the same as for the Blue Streak. But where the Blue Streak truly is limited to eight by its valve design, you can cheat a bit with the Ace. Of course, the law of diminishing returns quickly asserts itself and more than 10 pumps is really a wasted effort, so we did our chronographing at that level.
At four pumps, our Sharp launches its oiled Premiers at 553 f.p.s. with only 14 f.p.s. extreme deviation in a five-shot string.
On 10 pumps, the Sharp averaged 786 f.p.s for 10 shots with oiled Premiers. Extreme deviation for this string was 19 f.p.s. That works out to 19.62 foot-pounds of muzzle energy with this medium-weight pellet. The energy grows to 25 foot-pounds with super-heavyweight 29.6-grain Korean Dae Sung pellets.
The best our Sheridan can do accuracy-wise is a five-shot group of 0.204″, center-to-center at the same 10 meters. Of course, this is with the open notch and post hunting sights that come standard on the rifle. They are much less precise than even the simple aperture sights on the Sharp.
I used the Crosman .20 caliber Premier, which weighs the same 14.3-grains as the .22 pellet. And, on the recommended eight-pump maximum, the Sheridan averaged 639 f.p.s. with 17 f.p.s. extreme deviation. This gives 12.97 foot-pounds of energy. Were you to over-pump the Sheridan, velocity wouldn’t rise much, for the valve simply wouldn’t dump all the air in a single shot. And you couldn’t use the .22 caliber Dae Sung pellets in the .20 caliber American gun, even if the velocity were fast enough. The .20 caliber Premiers are about the best pellet for this rifle. At five pumps (the test target level), the Sheridan averaged 554 f.p.s.
There you have it. A test of the legendary Sharp Ace compared to the all-time favorite Sheridan Blue Streak. Although the Sharp fails to equal the American rifle in some quality categories, I have to crown it the champion for accuracy and power. I guess that says a lot for the legend, doesn’t it?
Is there a scope groove/rail on it?
ajvenom,
In the photo of the rear sight, it looks like there are grooves in the receiver. In fact, it appears that the rear sight is clamped onto those grooves.
Edith
Morning Edith,
Thank you for sharing the gun cleaning routine that you and your hubby use together. The mental picture your words wove put an smile on my face.
Mr B.
BB… thanks alot for the article! i really enjoy reading it and its very informative… I'm a BIG sharp rifle fan… i always wanted one since i was 14 and got them by the time i almost 33 years old! by the time i shoot with itm its just love from the first shoot… =)
Sharp Rifle is still imported to my country (Indonesia)… the recent one definately have better triggers design… its butter smooth even with 8 pump.. BTW… the trigger is metal, its just have plastic trigger shoe…
i usually just use 3-5pump.. its very hard hitting in .177 … and it definately love superdome… my shoot groups is similar to your measurement but in 20m range (but with scope)… accuracy&power is really where the ACE shine….
one again, i really appreciate the article… thanks for respoding to your blog reader…
PS: your podcast ROCKS!
*Iyonk.
Actually the groves on my Inova and UD-II are long enough for a scope ; though I've never had a scope on them. Look to be about 11mm.
Al
OT…took my Nightstalker and the Walther P22 Red Dot I just received from Pyramid into my local firearms dealer to have it boresighted. I figured the 20 bucks was worth the time I'd spend sighting it in myself.
Anyways I was a little nervous taking it in. I was a wee bit worried that they'd laugh at my little toy.
What in fact happened was that when I took it out of the case I got comments like 'how did I like the Beretta' and one guy behind the counter asked when did they start making it in .223, I think from noticing that the hole in the barrel end was way too small for 9mm.
Anyhow, when I told them it was a pellet gun, that it was 12 shot repeater and that it gets just shy of 600fps they all lined up to have a closer look.
And they were all quite impressed.
As was I.
It appears that a 'gun nut' is a 'gun nut' no matter how the projectiles are propelled.
Unfortunately had a close look at the 'real' CX-4 Storm they had in stock.
I WANT IT!!
By the way…the next day I tried the new Scope. At 25 yard I have not problme putting all 12 shots in a 1" circle.
That little Nightstalker is damned accurate.
CowBoyStar Dad
Just a question about the moisture left by air cooling in the barrel. Does this affect pre-charged air guns as well? It seems that would be a point in favor for brass barrels (in addition to them being easier to rifle).
I like having different types of powerplants in airguns. I have a couple springers, several Co2 guns, a couple multi-pumps, and one PCP. I love them all. I'm working on an airgun that will someday be powered on human gas. Cross your fingers people that day will soon come.

RE: Groundhogs
Is it possible to bait them to get them to move to a specific spot? (For example using deer-corn?)
I have about zip luck shooting squirrels in a tree with my Daisy 22SG. So I built a feeder in a nut tree to position them so that I was at a constant distance. I also now get to use my car as a blind. There is a backstop so pellets don't zing around neighborhood. Works very well.
Just wondering if same thing would work on groundhogs. The Feeder would be on the ground of course not in a tree!
His Own Brand,
Now your talking self control…
Diet is everything takes on a new meaning!!
Where do I sign up for a prototype?
Wacky Wayne
Wayne,
I'm still working out all kinks. Getting the gas to the reservoir has been a tight squeeze. I busted a few o-rings. I let you know on my progress.
B.B.
Another Japanese rifle! I think the Blue Streak is doing pretty well with the .204 group with open sights and I would be interested in how things improve with the Williams peep sight.
Edith, I have no doubt that Tom Gaylord can be quite hysterical when he wants to be.
Wayne, thanks for the verification of the Leapers quality. I just found out that smallbore competition has an optical component where you can put scopes on the rifles. That would be something to show up with an Anschutz 1907 and a $100 Leapers scope and show them what's what. They don't shoot further than 100 yards I believe.
Vince, you're right about the elevation for maximum trajectory. I think B.B. said it is about 30 degrees because of air resistance.
In the David Tubb book, he says that his goal in competition is not to make big mistakes–in essence, not to screw up. I can relate to that. Of course if your average is 795 out of a possible 800 that makes more sense. But I believe that he got to this level with this strategy. He said it is important to always raise the standard. It's another Miyamoto Musashi samurai connection. Musashi claims that with a difficult opponent, you don't administer the knockout blow but you knock the corners off steadily. I suppose shooting improvement can work the same way.
Matt61
Wayne & Matt61,
A scope on high power is darker than at lower power because only the light the contributes to the image counts.
On high power lets say you see a blade of grass and some background. Only the light from that grass and background will reach the ocular lens (the one where your eye is).
On low power you see the whole bush behind the grass blade. All of the light from the grass plus the bush reaches the ocular lens now making it much brighter!
Volvo,
Thanks for the photo.
What an incredibly beautiful gun!! I'm still learning about these classics but it looks like an LG 55 (M?)?? Looks brand new. What classic lines and impeccable checkering. Hope the finish is as deep as it looks. Can you tell I'm drooling with envy?
I can't wait to hear about when you get it in your hands and start shooting.
Did you see my offer?
kevin
Wayne,
Before you sign up with Hands on Guy for a human gas powered "air" gun, I'd suggest some research into how the gun is gong to be hooked up to its source of human gas. Quick release fitting, drill and tap for a permanent hook up or what.
Just a thought,
Mr B.
This gives a whole new meaning to "natural" gas.
Edith
Mr. B.
I'll test anything once! just think of the collection value!
hooking up the plumbing fittings as we speak.. 🙂
Wacky Wayne..
Has anyone besides me stopped to consider just how unpleasant a match with 'human gas-powered' guns could be?
Joe,
You've got a good point there… a very good point..
and what if there is a leak in the plumbing?
I may have to reconsider!
Wacky Wayne
Guys,
You're over-thinking the issue. Who cares if there's a leak in the plumbing during a match? The gas would have been emitted on the course anyway. What difference does it make if a little leaks out? There's more where that came from…and the course would have the same "conditioned air," even if you'd all been shooting springers.
Edith
Not sure this is what Musashi was referring to when he claimed with a difficult opponent, you don't administer the knockout blow but you knock the corners off steadily.
Gives new meaning to knock out blow.
kevin
Anonymous,
Thanks for the explanation about high power scopes. Your explanation sounds consistent with the idea that scopes at any power will give you less light than the unaided eye. That surprised me and is at odds with a lot in the gun literature. It's not hard to come across ads showing a dim background with a brighter image of a bear appearing through a scope as though the scope increases illumination.
Kevin, I don't know that anybody knows what Musashi meant which gives one a certain freedom of interpretation. He does indicate somewhere that his procedure, "The Way," is supposed to apply to everything, so that would include shooting. Received your pellets–thank you–and will report shortly.
Matt61
Matt,
RE: Scopes
You're missing the point. The objective lens of a scope is a lot bigger than the pupil of your eye will every get. So yes a good scope will get more light than you eye. Think telescope. A 50mm scope gets more light than a 40 mm scope, than a 30mm scope and so on (scope quality being equal…).
No doubt you've seen some of those really large, high powered lens for long distance camera shots. The lens is as big as a dinner plate. That is to get more light. But with a bigger lens, the quality of the lens has to be better to focus the light right. For a rifle, a bigger objective lens also means that the scope has be further off the boreline. So a 300 mm lens which would be OK for a camera, would be 13" or so above the boreline. That wouldn't work very well…
If you have a 50 mm scope on high power (18x?) you're only getting light from say a 2" circle. If you reduce the magnification to 9X, then you're getting light from a 4" circle which is an an area 4 times as large.
!@#$&*()
The center of a 300 mm lens would be about 6.5 inches not 13" above the boreline.
Matt61,
A scope will always give you more light than your unaided eye. The amount of light gathered is a function of the size of the objective lenses. The size of the lens of your eyeball is relatively small compared the objective lens of a scope or a pair of binoculars. In the old days, before the advent of electronic image enhancement, a night glass(es) was a telescope of binoculars with very large objective lenses.
You can test this yourself with a pair of binoculars in low light. You will be surprized as to how much brighter and how much more you can see with the binoculars than with you unaided eye.
Mike T.
Two things – basic viewing for deep sky objects, the smart money is on a pair of 7×50 binoculars, exactly because they gather more light than the naked eye. The higher the power, the larger the objective lens must be to keep the light gathering power on an equivalent scale – ie a 10×50 pair of binoculars actually gathers less light than the 7×50 pair.
Regarding human gas powered weapons, my first day back at work after a two week vacation, I was unfortunate enough to be sitting next to a lady on the PATH train who was emitting her own source of propellents. Made me realize how much I enjoyed my vacation. However, it wasn't as bad as some of the folks on the train who have a diet HEAVY in curry. Man, the smell of those "propellants" make the mustard gas that Saddam allegedly had a joke 🙂
I'll stick with compressed air, thank you very much!
Fred
One of the benefits in using your own human gas is that everyone loves their "Own Brand." It might be offensive to others near you. But you could bask in your own glory. Then again, you won't have to ask them what they had for dinner. All joking aside, I think people are really going to consider this power plant before they look into getting a PCP. The first model will be a carbine and it will be called Thunder Clap. Speaking of Sharp rifles, perhaps I could release a clone called the Shart rifle. Just a thougt.
P.S. j/k, although it makes us wonder, is it possible?

and now for a break in the flatulence[sp.?]!this weekend at the flea market,I purchased a Feinwerkbau 150 match rifle with a Bushnell Scopechief II 4x!I paid 450$ for this combo.I don't know if I got a great deal,just that I paid what I was willing to part with to take it home.this gun cocks with my index finger!Thankfully,BB's blog warning kept me from oiling this beautiful match rifle.can anyone out there tell me anything more about this model[other than shoot it level!!] thanks!
Fred, I always laugh when I see the department store telescopes…you know, the ones with a 60mm objective lens and 300 power.
300 power on a bright sunny day.
If I remember correctly, the rule is that for astronomical work 20 power for inch of objective is about the maximum to really see detail.
So that 60mm scope has a usable power of about 40x.

nice air rifle Frank
Scopes,
An optical system such as binoculars or a scope can be thought of as collecting the light in at the objective lens (closest to target) and compressing it out the ocular lens (closest to eye). So the larger objective you have, the more light you collect.
But as Herb clarified, it is the area that you are collecting the light from that makes it so a variable power scope is brighter at low power and dimmer at high power. At high power, it may be collecting from a 2" diameter while at low power it is collecting from say 10". There is more light coming from the 10 inches of source than from 2 inches of source.
The important thing with scopes for brightness is the exit pupil, which equals the objective diameter divided by the magnification. E.g., a 50mm scope at 10x has a 5mm exit pupil. If the exit pupil is as big or bigger than your eye's pupil dilation, the image will be as bright as possible. The human pupil's dilation can vary something like between 2 and 8mm, with older eyes dilating less and more slowly in response to dark conditions.
If the pupil's dilation is smaller than the exit pupil, the exit pupil is clipped, resulting in an effectively smaller objective. Generally an exit pupil smaller than the eye's dilation will be tolerable until it reaches a lower limit which varies by the individual at which point the image degrades beyond usability.
As magnification increases, the image will grow dimmer, due to magnification (same light spread over larger area) and the decreasing exit pupil will eventually become so small that it can be affected by imperfections in the eye, resulting in floaters and the like.
As far as quality, all scopes follow the basic rule above, but higher end scopes often have more and better coatings, which can make a difference because the transmission rates of all the lenses in the system are multiplied together. For example, a low priced scope with three "fully coated lenses" (single antireflective coating on each lens surface) might have a throughput of (example values only) .9^3 = 72.9%. A high-end scope of the same design but with fully multicoated lenses might be .95^3 = 85.7%. The difference may be noticable or not, as our response to light levels is not linear.
OK, serious time. The Feinwerkbau Westinger & iAltenburger GmbH produced the model 150 fromm 1961 to 1968. It was the FIRST FWB airgun with the patented recoil-compensation sledge system. Muzzle velocity is rated in the 450 fps range per my Blue Book of Airguns. A rifle with a grading of 80% goes for $475 and there is no mention of a scope. The book also doesn't mention if this rifle came with aperture sights, either. If your rifle has a Tyrolean stock, the price increases by 60%. Assuming your rifle is 95% grading, the value is assessed at $600, $800 if 100%. The Blue Book goes on to say that most existing speciments are heavily used by individuals or shooting club members. I think you got a great deal, Frank B.
Iyonk,
Well, today's blog was for you, so I'm glad you liked it.
B.B.
Kevin,
Sorry it was not timelier, but I sent you an e-mail earlier today. My PC access is very limited during the day.
As I stated in the e-mail I think the LG 55 deal has gone sideways. Oh well.
On a seperate note, thanks again for your generous offer.
BG Farmer – you nailed it on the scope brightness answer. I was planning on saying almost exactly what you wrote to contribute (optics are one of my strengths). The exit pupil is the most important factor, and it never gets any mention! Whenever I look at optics I always mentally calculate the exit pupil (or range if variable), and if not reasonable (around 5 or 6 if fixed power, or 2.5 – 8 if variable) then pretty much discard it from coinsideration.
Vince and BB – Thanks for your input on my Quest 800. I have been considering doing the tune myself, but I'm sure a tuner would do it better, so I think I'll go that route (spending the extra $80 or so over the parts for for me to do it) to make this the best it can be, and then save a while for what I really want – a Maurader. I love everything I read about that gun, but the entry price sure is steep when you don't have a pump or anything else to support the gun.
Thanks again!
Alan
Thank you AJvenom,thank you BB!A BIG OL' thank you Fred!!!This one is a 98% with light one-owner use.Hand carried from Germany in 1967.the man bought it for his brother who has since passed on…I'm pleased about the value,but more about the quality!!The man was retired military,so I wouldn't have felt bad had I overpaid,times being tough for those on fixed income…I'm a soft touch I guess.compared to other guns of known velocity I own and pellet backstop penetration I would guess this gun is shooting mid 400's.BB's ballistol trick cleaned it nice.this thing is like a vault door,real solid!!!cocking it reminds me of the rollercoaster clicking before the top of the hill.I wish you were all here to take a turn!!
FrankB,
Wonderful find. Wish I could be there to take a turn!
Do we see a blog coming from you??? That'd be as close as we'll get to a admiring her seductive lines, pulling her into our scholder and gently caressing her trigger. Thanks

Frank B.,
The guys on this forum can help you with your new 150, which you got as a good deal.

B.B.
Alan, if you can get a polish, lube and some trigger work done then 80 dollars isn't that bad for a quest 800. That's basically, all I've done, but I did add a GRT-III trigger.
I've done a little work to all my aiguns and that's why I would have a hard time selling any of them. They all are set up the way I like and I like a variety of airguns. They all have their pros and cons, but a smooth shooting .22 springer makes an excellent hunting tool.
My Quest 800 has lasted three years and have had no problems. Well, except for learning how to shoot a springer, but once you have the artillery hold down, you'd be amazed how well you can shoot one.
Here again is my collection, with the picture of the Disco added. I've did add a second barrel band and may try the .177 barrel on it someday. With a trigger mod and power adjustemnt screw, the Disco can be a sweet air rifle for the money, but all togather new the Marauder is probably the way to go.
http://picasaweb.google.com/ajvenom1/Ajvenom1#
Right now I have been working on the setting up on the Disco and have been nailing some .240" ctc 5 round groups at 20 yards with Eun Jin 32.4 points. approx 18 ftlbs 500 fps. 70-80 shots per fill. I still run 1700 to 800psi and with 75 pumps = 1 pump per shot like a springer.
I'd love to see some of the Sharp's internal bits..how is it possible to keep the blow-open valve airtight, yet keep the valve stem easily movable? A heavy O-ring would squeeze the stem is such a way that it won't fully return?
Mel,
Although this isn't the way that it works, one way to envision it is like a deadfall in which a thin stick holds up a heavy log until the trigger is tripped. Then the stick moves out of the way and the log falls.
A mousetrap is another way to envision it.
B.B.
BB,
I wonder why there are not Japanese airguns other than the Sharp. Moat things made in Japan seems to suggest high quality, it would have nice to have pcps made in Japan. Some of the best scopes are made in Japan, why not airguns?
Thanks.
Abel
Able,
There ARE other Japaneese airguns. Did you not read about the Taiyo Juki?

I have a Sharp Ace rifle purchased in 1998 and until now I still use it to hunt pigeons in tropical forests of the island of Timor. during this air rifle had never been broken and very accurate. More than 500 pigeons I shot had for 10 years.
I too have a Sharp Ace, however it is the model with the thumb hole in the stock. My only complaint is the trigger, very hard to pull and not smooth at all. Anyone have an idea on what to replace it with and how? Sure would like to replace it.
Dabve,
There is no easy way to replace the trigger on a Sharp Ace. It is part of the firing mechanism. It becomes harder to pull the more pump strokes you put into the gun.
Sorry, but you'll have to live with this one.
B.B.
This is a Japanese web site that upgrades ACEs Triggers are one of the things they work on. Not cheap. They also replace the arm on the pump and replace it with tempered steal. They are located in hokaido I think. You will need to have someone who speaks Japanese for help.

Aaron,
Thank you for that link!
B.B.
thank you for the information above. I have had two ace rifles and believe it or not, I’ve shot several wild pigs, kangaroo’s, wild turkeys an huge jungle doves, here in Papua.
Mind you; Americans sometimes are so naif. They usually say: you need more power, take a 22 rim rifle.
Well, we are limited to airguns, and to .177 cal. only…..! So now I have a ARS Hunting master in this cal. using huge Sam Yang, or Barracuda Handel and Natermann 16 gr magnum pellets. I tuned up the rifle so that the heavy pellet goes through a D-CELL battery at 35 yards, that is about 30 mt rs+. This power is enough to penetrate the lower ribs and heart of most wild boar en medium dear. I have shot already dozens of them. WITHOUT THE USE OF A 22 RIM RIFLE !
Now I have learned about the first PCP Sharp air rifle. I bought it, and to my delight it performed well on targets.
The relative small tube beneath the barrels seems to have a built in regulator, which I’m not really sure of. But I get 23 clean shots entering 1 inch at 25 meters with the same penetration as my old ARS HM.
Here is a question: from a Sharp Ace or Sheridan Pump up rifle with 10 pumps, how much pressure is there behind the pellet: 10 bars…..? Compared to a PCP: How many bars in pressure is there behind each shot ?
Who can tel me more about it ? Thanks.
I am going to experiment with making an own rifle Using the Ace firing system, but so that after pulling the trigger, a special valve prevents all the air in the pressure compartment leaving the reservoir. I designed it myself.
Thank you giving me the opportunity to write this comment. And for those of you who want to do a survival-hunting trip, carrying a PCP. through the densed jungle of West Papua, consider yourself invited.

James,
Welcome to the blog.
No one (including Sharp) knows for sure how much pressure the gun develops, but it’s around 1,200-1,800 psi.

BB,
Magic 9 Design Ltd in the UK has just manufactured a short run of Sharp Ace trigger blocks to the standard pattern but in high quality aluminum alloy, not showing on their website yet but I’m assured they will be shortly,
