RX2 .20cal owners, can you tell me your chronograph results for h&n field Target trophy pellets. Or the beaman field Target specials chronograph results. Much appreciated

I owned a RX1 in .20 cal and 11 gr Beeman pointed Silver Jet pellets shot 910 fps. That at 85 ft altitude. At my brother's home at 2300 ft altitude velocity was down between 880-890 fps. I assume the RX1 and RX2 are similar in power. I'd say a good functioning 5mm RX2 at sea level with the 13.27 gr JSB's should shoot between 830-860 fps.

The speed is really up to how much pressure you have in the adjustable gas ram. They work well from 6-20 FPE. I like them best at 12-14. They become increasingly hard to cock and there is a point of diminishing return. They will burn up seals if you over-pressurize them as well. I have 2 in .20 and they are wonderful! If they had the Rekord trigger, now that would be outstanding!

Is this the Lewis that we were once talking about the rx that was in the pawn shop? Because remember I told you a relative of mine was doing bad stole it and sold it? If so then this story has a good ending, because I have it back.

Same old Lewis.
So glad to hear you got it back!!
Let me know if there is anything I can do to help you out.

Should shoot in the 880-900 fps with that pellet. I didn't know the RX2 had power adjustability. My RX1 did not.

I shoot the heavy .20 JSBs in a D54 sidelever.
They go above 800 fps at impact and basically act like a live .22 rimfire.
The RX is a gas ram. Not as good as the Theoben Eliminator gas ram but hanging on the coat tails of it.
I have the .25 Theoben Eliminator which never malfunctioned since 1999.
Twenty years! It is still the best most strongest and accurate .25 caliber rifle I have to this day outside of PCP.
The RX Beeman Series copied the Theoben but the copy isn't as powerful.
It costs half as much for an RX than a Theoben Eliminator.
I feel the velocities mentioned in this report about the RX .20 doing over 800 fps in an accurate lead pellet is wrong.
In a D54 the "light" twenties from jsb exact begin to approach 850 fps.
My Theoben Eliminator .25 does 705fps.
My D54 .20 does over 800fps using heavy jsb .20 diablos.
The RX does not have the velocity of a true Theoben.

More bad and completely incorrect info. The RX line of rifles has a THEOBEN designed gas ram for the HW company! It's power is as Theoben designed it and NOT underpowered. Numerous other true Theoben rifles are less powerful than the RX series and again by design. Mentioning a 54 or Eliminator has nothing to do with OP and is not helpful especially when they have been mentioned over and over and over again.

At 800fps a .20 caliber pellet acts nothing like a rimfire. A .22LR has around 98fpe at the muzzle. Your .20 caliber would need about a 70gr pellet to approach that. With the heaviest pellet listed commonly available, the 15.9gr JSB, you would be making 22ft/lb. That's similar and attainable energy from a common HW80/Beeman R1.
The RX doesnt make the power of the Eliminator because they are different guns, with different stroke lengths, not a copy. The Beeman Crow Magnum is the rebadged Eliminator, and they are similar if not identical powerplants.
Nothing here in this thread has anything relative to your RWS side lever.

Ok dualmagmaike, so true and thank you. So what is your opinion as to what it should shoo using the FTT's? I am just trying to get a consensus but you my brother I should have seeked out. And to the gentleman who said that I or my rx doesn't have a theoben ram, sir, it is a theoben made ram. Even says theoben on the side of it.

And Lewis, I'll try to call you as soon as I get done work. Thanks for everyone's input and feedback.

I do not own a .20 so I will not comment. This is what Straight Shooters site had for info on the RX2, also if you haven't already noticed THEOBEN is clearly stamped on the side of the rifle (I know you know this). Isn't it a bit odd to "feel" something is not correct when that someone does not have any experience with it?!

Mike,
Thanks for the table! it shows exactly where these rifles are expected to be operated at, 15-18 FPE. Lots of folks pump them up a bit to the 20 FPE range but as stated earlier, this comes at the expense of much increase cocking effort and increased potential for dieseling and piston seal wear.
As others have pointed out, the RX line is not a copy or derivative of a Theoben ram, it IS a Theoben ram.

Interesting Lewis ! I haven't had a gas-ram airgun where the ram pressure could be adjusted since a Theoben Sirocco Classic in walnut that I owned in the late 1980's. I owned a Beeman stamped Theoben Elliminator (Beeman Crow Magnum III) and it may have had a Schrader type valve in the receiver end but I don't remember.

I had a Theoben that didn't have the power of my RX1. As mentioned, not all Theoben rifles were "magnum class " . You've got to remember the United Kingdom law regarding airguns over 12 ft lbs.

I had a whole back and forth just the other day with a guy on FB who thinks 24 fpe is OK but caliber will play a large role. I have actually had several people say in that range is fine or they are capable even in .177. Each and every time I ask them to show where HW says these rifles are rated to those numbers (in .177 or .20) silence and or sarcasm follows. Ask D Slade or anyone who really knows them about 24 fpe for an RX/90 and see what they say. The tables above are likely with a new gun and slightly higher velocity may come with break in but not usually a substantial amount. There are a number of 19, 20 and even some 22 fpe numbers and even 2 cases where 24 fpe was mentioned by Straight Shooters tests for the RX2 but these were for .22 cal.
Here is a clip right from an HW90 manual for those who may be interested "The air pressure is already preset to an optimum level during manufacture. This preset level offers the best relation between accuracy, cocking effort and muzzle velocity. This level may not be raised, but only reduced"

Maybe it's just me because my first one I ever owned seemed more accurate, more "powerful" and smoother cocking than this one now. Who knows...I do have a Hill MK 2 or 3 pump and the adapter to add air.

All my Theoben have a slotted screw or Allen at the rear of the compression tube except my Sirocco Deluxe. On the deluxe it's still adjustable (I believe) but must remove the stock or possibly the ram to do so again via a Schrader valve. On all the rest remove the screw and find a Schrader valve underneath, attached pump with proper adapter and adjust up to factory/legal limit.

My RX was upgraded by Beeman to a RX1. I for the life of me don't remember a Schrader type valve on that rifle Mike !
