Title: Accuracy in a gas piston air rifle
Post by: Hammer47 on January 09, 2015, 12:48:59 PM
What gas piston air  rifle will give the best accuracy ?  I know they will vary but certainly there has to be a prohibitive favorite.

^^^^^  i completely agree with the above post lol



but,your question cant really be answered with any absolute certainty.

because,

every gun is different,some like the artillery hold and some seem to prefer to be held tight.

all barrels are different,
2 of the same exact barrels may not like the same pellet.

and all shooters are different levels of shooting experience.


a gun that has been gone over and tweaked by someone that knows what their doing,
will generally shoot more accurately than a gun pulled right out of the box though.

The Weihrauch HW 90 probably comes the closest out of the box.

Why does PCP have to pop up in a question that has absolutely nothing to do with it? PCP is not the do all, be all powerplant for everyone, especially for people who can only afford gas rams. Sorry to be cranky, but this to me is flaunting. Please keep PCPs in their proper gate or within context. I could see bringing it up if it was an open ended question about airguns in general, but this is not. Personally I am sick of hearing about PCP. I avoid the PCP gate for that reason.

I am usually an easy going guy, but c'mon man! Let's stick to the subject, please.

I only have experience in two low-end gas ram guns, a PA tuned .22 Gamo Bigcat (before Gamo started offering their IGT powerplant) and a Benjamin Varmint in .22 which I believe is the same as the Crosman Nitro Venom. To me the Crosman/Benjamin gun is less hold sensitive but both are equally as accurate. The Gamo had a sweet spot at its balance point and the Varmint shoots from anywhere just about. I'm getting one ragged hole at 15yds with the el cheapo packaged 4x scope. If I had the funds, I'd like to try an English or German thumper.

Another vote for the HW90 here, especially at medium gasram pressure the HW90 performs very, very smooth. Especially in .177. Way better compared with a super duper tuned springer.

The HW90 elite trigger is the best one I've ever experienced. Even better then my Diana T06.

Dang, that reminds me I still want one  :P

Two that were not mentioned were the Beeman RX2 or the Theoben  Gas spring All three can be adjusted by tuning the pressure of the cylinder to change the fps to the pellet weight being used

The RX Gas Rams that I've previously owned were very consistent shooters. Because of this, they were inherently very accurate rifles that often exposed shooter error as the result of inacuracy. Once a particular pellet is set up at its own prefered power and velocity range, these rifles are dang hard to beat. The old .20 RX rifle I had ( which by the way I saw for sale on a forum classifieds) was an absolute dream shooting Benjamin Sheridan cylindricals at 14 fpe. It's like you couldn't miss with that rifle. But that was this rifles particular optimal power setting with those pellets. I loved hearing them slap tin cans and water bottles all over the target range ;) The triggers are pretty dang good too. I liked the ability to reset it without recocking the barrel. Uncocking was also a nice feature I've found on all the R series Beeman/HW made break-barrels. They are classy guns for sure. Hth's :) tjk

is a gas springer more accurate than a coiled steel spring springer ? and why ?

I wouldn't say more accurate, because in 99% of the cases it's the shooter not the rifle that causes accuracy, but a gasram is more easy to shoot. It's not hold sensitive due to the short shot cycle and therefore it is being experienced as being more accurate...

I believe you will find the most accurate Aiguns are spring powered and the reason has nothing to do with the powerplant.  I have both and like the feel of my NP but my springer hits the target more often.

I am an experienced spring piston shooter, but have also been thinking about going with a gas ram, so thanks for the post.

I'll add a question or concern of my own. I did have the original Benjamin Nitro XL in 177 and, frankly, that thing was a nightmare. I did everything under the sun to get it to shoot and never did settle down. Okay, some guns are like that. The biggest issue for me, though, was the enormous cocking effort. As a gal, I could get the thing cocked, but I had to rest the butt stock on the bench and then use two hands to break the barrel. Darn thing wore me out. So my question is this: are all gas piston guns going to have this kind of cocking effort? Are there models out there with a little less velocity so as not to require that kind of effort?

Yes the Beeman RX2 / Weihrauch  HW90 and the Theoben gas rams are able to have the power adjusted. The fill gas ram has a schrader valve so the HP air and the special fill probe can be used with any of the 3 or 4 stage hand pumps used for PCP. This can be used when a need to adjust the pressure  in the ram is required by the user. That is the extent of my knowledge since my RX2 .177 is on the way to me as I type and I have not ordered the fill adapter yet ;D

Post by: mobilehomer on January 09, 2015, 07:56:29 PM
Joanie, I have a Nitro Venom Dusk and a new Trail NP2. The NP2 cocking effort is at least 30% less than the NVD.
I have read others that said it was harder. Mine is so easy that I don't have to "slap" it to break it. Just a gentle stroke gets the job done.
In a week or so, when the weather breaks a little, I will do a full review.

My HW90 in .25 is de-tuned to 21bar and is a pleasure to shoot...After installing a Vortek seal, I used my Benjamin hand pump to adjust its pressure while testing pellets...It likes the 21g H&N FTT and pushes them at 707fps average @ 21bar...

The Umarex Octane can be a very accurate gas piston rifle, but is a pretty manly gun at about 9.5 lbs with scope and 26 ft lbs, requires proper hold to be really accurate.
Title: Re: Accuracy in a gas piston air rifle

Post by: D14Jeff on January 10, 2015, 12:00:32 AM
you can always get a metal spring magnum springer and detune it with a shorter spring . then get a full power spring when you're ready for it . the accessories to change pressure in a gas ram cost as much or more than the gun so have deep pockets . but is you can afford all that why not go PCP ? a B50 and a pump will have more power , no recoil and cost the same or less .

Ok George, you ask.... It's because the man is concerned about accuracy in an air rifle. Truth be known, you are way way way more likely to get an accurate PCP rifle out of the box than you are a springer, gas or no gas IMHO and I think lots of experienced air rifle enthusiasts would agree with that statement.

I find that my Crosman Titan in .22 is sufficiently accurate for me. I have taken squirrels out to 40 yards with it. I have killed flies and possums at 16 yards with it. It loves jsb 18g pellets. I have had it for quite a while 4 or 5 years maybe? I have a discovery pcp and I find for most things I pick up the Titan. Great go to gun with good power and accuracy for the price. Definitely a value.

 ;D I am fortunate to own and enjoy a nice variety of AG's 1 old  Daisy  880 .177 pumper and it gets used from time to time . My D460 ,TX200 and D34P get used a couple times a week I also have a new to me RX2 on the way. Then there are my PCP's which all get shot several times a week also. I guess where this is going is buy what you can afford or maybe slightly more as long as the food gets on the table and all the bills are paid and enjoy the heck out of it . If it is not perfect at first save some money and do some homework/research then start making it yours with easy simple upgrades. Unless you are a perfectionist with unlimited funds ( ;) Sharky) most decent modern AG's will get it done it just depends upon what you expectations are  :o ;D

PS: For me unless I can get a single ragged hole at 25 yards it needs some TLC I won't go into any further detail  other than to say there is a bell in someone's backyard set out to ~ 50 yds that I like to hit a minimum of 6 to 8 out of 10 shots  ;D ;D ;D

Kyle..........If I am ultra concerned with accuracy I will use my AA400MPR or my FWB C60 or my Baikal M532 or my FWB 601 or my FWB 300S,  etc., etc.,etc.  The reason I ask about a gas ram is because I shot one the other day and was impressed with the ease and simplicity of the concept.  I asked about accuracy so I need only to buy ONCE and save the aggrivation.  This thought was by no means a springboard to launch a pissin' contest.  Pcp's surely have their place but it is the simplicity of the gas ram that currently has my attention and I wish to know if there is TRULY an ACCURATE ram available.  If these guns are only moderate in their accuracy I won't be a player.  Only accurate rifles are interesting.

then I would suggest Beeman RX2 or HW90, BUT I have heard sometimes the .22 barrels are not as accurate than their .177 barrels.

Sorry if I came off a bit crabby, but if anyone has a right to be crabby, it's me. My dear mother passed away on New Year's day and I am still reeling from that. Kind of puts things into perspective.

  A lot of how accurate it would be depends on the users ability to shoot the gas ram gun. I'm sure my 125 sniper would shoot less than 1 inch groups at 50 yards with a gas ram since it will a spring. Problem is not everyone would be able to get those groups do to the slightest change in the position and hold of the gun effects the group tremendously at 50 yards.
 I'm sure there is a lot of gas ram guns capable, but generally something in the 12 ft lb range from England or Germany is going to be much easier to shoot accurately. By that I mean dime size groups out 20 or even 30 yards.

;D  Craymar , Not to be contrary but if you take 10 identically set up but different manufacturers rifles and take 10 competent shooters have each shooter set up and shoot 100 shots with each rifle and compare results and what you will find is that no matter which rifle is shot the shooter with the best and most consistent form will get the best results no matter which rifle he/she uses

What?!?!  SMH. If you are not directly familiar with this type of ram please don't comment. You're just speeding poor, inaccurate, and misleading information. The adapter is $30 and you don't neccesarily need a high pressure ( and overly priced ) pcp type pump.  a bycicle tire pump will do if you can locate the proper fittings that aren't that hard to find and purchase. They ain't that much money either. I have the original Theoben pump and it is by no means a high pressure pump. Forget the Weihrauch pressure gauge. All you need is a simple $60 F1 chrony, a pellet size and weight chart, and a FPS to fpe conversion calculator found on every airgun forum known to man. With these simple tools, you can calculate pretty dang close where and what power level your RX/Hw 90 ram is shooting at.
I would also like to add that if a poster makes an inquiry about a certain type of airgun, I feel it is very inappropriate and in poor taste to mention other types of airguns. This is why the forum has a personal email/private message feature.

 ;D I will only add a little to what tjk has posted the deep pockets thing is rather subjective two of my friends and fellow members from Southern New Jersey Have what some might consider "deep pockets" relatively speaking Others here might consider me to have "deep pockets" . Reality is that what I and they have spent is within their comfort level pursuing their hobby/ passion/addiction. Call us crazy or foolish but for me I am having fun in my dotage.and as far as needing a HP pump from what I have read do far the standard bicycle hand pump misses the pressure mark by several hundred pounds , please correct me on this last bit about the operating pressure for a Theoben gas ram. The rest of my statement I stand firm as they things stated were said with first hand knowledge of the subject .

What gas piston air  rifle will give the best accuracy ?  I know they will vary but certainly there has to be a prohibitive favorite.

is a gas springer more accurate than a coiled steel spring springer ? and why ?
I doubt it.  I have a Diana 48 with a Vortek kit and the shot cycle is amazing.  No torque, no vibration, no spring noise at all.  5 shots into 3/4" or better at 35 yards is no trick at all.  And the bit about you can't leave a springer cocked while out hunting is a red herring IMO.  I leave mine cocked for an hour or more sometimes.  I have over 3,000 shots since I installed the kit, and my avg. velocity has actually increased by  about 10 fps. since the last time I chronied.  Having said that, I'd like to try a gas ram rifle.  The selection of quality guns with rams is very limited though.  I've tried Crosman, Gamo, and Hatsan guns and they have all pretty much been disappointments.

How much pressure you getting out of a tire pump?
the RX2 can be charged to as high as 1000 psi the below was taken off a post on the yellow forum and they share many of the same members

I think if you look at the RAM (near the fill port) you will see the max pressure capacity. Examples of varying ranges like 26-Bar/377psi for HW-90 and I think 69-Bar/1000psi for RX2. I don't think you'll find a "bicycle shock pump" that's gonna any of the gas-rams. The gauge on my LVHP (Low Volume High Pressure) Fox Shock Pump reads to 300psi (don't think the pump could do it though), and typically never use this pump past 200 psi. I think you're gonna need something like a Hill Pump (like for pressurizing a PCP Air Gun).

Stupid is as stupid does. 1000 psi in a RX/HW90 ram???. Good luck with that. Let me know how that works out for ya ok?!?! I don't care what forum you may get your information from. Wrong is wrong. This is one reason I don't care to participate much on airgun forums anymore. Try to help someone out and you get shot down by folks to hyped up to know what they are talking about. Might as well talk to a brick wall.  When I can help people out wih first hand knowledge and information I KNOW from past personal experience, I will try my best to assist. If I don't know something about a certain airgun I keep my mouth shut. But Ive been down this road. If you want. Check out the old  GTA forum and you will find out my back ground. I used to be a moderator here on the good ole GTA. Really, it's uninformed people that spout out BS that makes the whole ideology of a forum such a joke and so not worth it. So with that good luck and learn things the hard way.

Stupid is as stupid does. 1000 psi in a RX/HW90 ram???. Good luck with that. Let me know how that works out for ya ok?!?! I don't care what forum you may get your information from. Wrong is wrong. This is one reason I don't care to participate much on airgun forums anymore. Try to help someone out and you get shot down by folks to hyped up to know what they are talking about. Might as well talk to a brick wall.  When I can help people out wih first hand knowledge and information I KNOW from past personal experience, I will try my best to assist.

:-[ Not stupid just misinformed but also not rude . after reviewing some other information including an old post of yours to Pac protector apparently on the order of ~21 bar or approximately no more than 400 psi is the proper fill and the best tuning results are achieved by using a chrony. In spite of your disclaimer you do care and I did find incorrect on the yellow I also was not trying to mislead I clearly stated that I was not yet I possession of the RX2 but was impressed with the reviews. Whenever I attempt to work on one of my AG's I look to others with knowledge about my specific project before I jump in to the deep end of the pool. If I came across as a fool sorry to have upset you and will say no more on that post

...... a bycicle tire pump will do ......

i have read on this and other forums that a bicycle pump won't make the pressure needed .
in this thread i was looking for feedback from folks about using a mountain bike front fork suspension pump to pressurize a vortex piston

http://www.gatewaytoairguns.org/GTA/index.php?topic=77017.msg733181;topicseen#msg733181 (http://www.gatewaytoairguns.org/GTA/index.php?topic=77017.msg733181;topicseen#msg733181)

because i seen a video on youtube of someone doing it . i know just because something is on the internet that it doesn't make it true or a good idea . no one here could confirm its validity so i dismissed it as a option . maybe i was wrong on that .

a b50 and a real pcp pump can be had for $370 . i did not know a gas piston springer with the accessories to change the pressure could be had for similar or less money . i apologize for my mistake . what gas springer and pump with adapter for changing the pressure/Bar would you recommend for under $400 ?

You can get the pump from Mike at Flying Dragons the fill adapter I did a search for Theoben fill adapter and can't help on the rest but I don't  know if the IGT and Nitro Gas Springs are adjustable they may be sealed units so it may only be in the Weirauch / Beeman and Theoben gas springs that you can adjust the pressure

Ok gentlemen. Please allow me to apologize for being a jerk and not showing a bit more compassion and respect towards my fellow airgun brethren,....and sisters out there as well. I previously have owned the RX series rifles and worked on them alot. Everything from setting them up to using different pellet(s) weights to total overhaul and rebuild of the power plants. These guns are simply fantastic and a thrill to own and shoot. The very fact that they are so versitile is what really sets them apart from the lesser cost/quality priced point "gas rammers". Not that there is anything wrong with going with the Crosman and Gamo types. So no snubbery or ill intent meant to those that opt for those rifles. But getting back to the RX/HW90 rifles, anyone that has the chance or opportunity to shoot one should. They might not be for everyone, but I doubt anyone will ever walk away from one and not feel first hand, the difference in quality and craftsmanship they are priced at. And the Theoben rifles are even better. So in closing, I would hope that this thread can continue in a more positive direction. Again my apologies. tjk.

I for one look forward to having my questions answered by someone who has hands on not just book/internet knowledge  :D

I have a simple rule of thumb. If I cannot afford it, I don't try it. Sort of like going to a BMW dealership and test driving one of their top of the line cars. Sure, it was an interesting drive, but now I see how junky my car is in comparison and there is no way I can afford anything else. I turned down a chance to have a very expensive rifle sent to me for free to shoot for a week for that reason. I appreciated the thought, but I'd rather not know what I am missing out on. :(

Sometimes ignorance is the best, most blissful option.

The RX Gas Rams that I've previously owned were very consistent shooters. Because of this, they were inherently very accurate rifles that often exposed shooter error as the result of inacuracy. Once a particular pellet is set up at its own prefered power and velocity range, these rifles are dang hard to beat. The old .20 RX rifle I had ( which by the way I saw for sale on a forum classifieds) was an absolute dream shooting Benjamin Sheridan cylindricals at 14 fpe. It's like you couldn't miss with that rifle. But that was this rifles particular optimal power setting with those pellets. I loved hearing them slap tin cans and water bottles all over the target range ;) The triggers are pretty dang good too. I liked the ability to reset it without recocking the barrel. Uncocking was also a nice feature I've found on all the R series Beeman/HW made break-barrels. They are classy guns for sure. Hth's :) tjk

i have the RX1 in 20 caliber...bought it new in 1989-1990...it will stay with me.

 ;D I expect the RX2 will be staying with me a good long while also. My rifles are beginning to be honed down to my keepers at this point in my journey.
