Title: Any Problems with the HW90?
Post by: DTHN2LGS on January 26, 2015, 02:29:01 AM
I'm wondering if there have been any problems with the Weihrauch HW90 that anyone has heard/read about?  I'm thinking it may be what I'm looking for, and didn't find much info on here via a search.  I'd like to know if this is a good purchase, or should I look at something else?

From what I gather the only comparable option is the hw80 which has a very simple design for take down and the trigger is better and more reliable.Also I hear the 90 is harder on scopes also due to the more jolting shot cycle. But of coarse with the hw90 being a gas ram you can keep cocked for longer and it has a resetable safety. Pretty sure the 90s a bit heavier with a higher cocking weight. So take all that how you will. People tend to complain about the rather plain looking stocks on both rifles. But that to me just makes for a better looking worn in gun! Don't need to stress the nicks and scratches you will eventually find on the gun! Imagine those scratches on a tx200 or hw77😬😬😬

The HW90 gasram can leak when you pump it over the adviced 26 bar from the factory. Personally I have experienced that the HW90 runs best at 21 bar. The results of that ?

Less cocking effort...
Less recoil (although since this is a gasram, it already has a very decent short shotcycle)..
It is better for the ram...

I've shot and owned many airguns, but the HW90 is the best springer ever build. Very robust. Believe me, the hW90 elite trigger is better than the record... Period.

Problem? The only problem I see is the price!

Seriously, no they are great guns. Some consider them a little on the heavy side, but the stock shoulders well. I have a RX-1 I bought brand new in 1998. Never done anything to it other than shoot it. it's never lost any power nor broke a scope.

 ;D Just got my new to me RX2 which is the same rifle with the exception of no open sights so scope only rifle. However I will add that in .20 shooting 11.42 gr Beeman FTS even though only 300 or so total between me and the original buyer this is a 20 FPE rifle and is already beginning to group well. This is a very nice well put together Break barrel with a nice solid smooth cocking cycle and once I lower the pressure and maybe 16 to 18 FPE should cock a little easier. Right now it is on a par with my Diana 460

I kind of expected the responses you guys gave.  I could not find much negative on here with a search.

I asked because someone on another forum said they are "breaking" (I don't know what broke) and he saw one "break" in front of him while the owner was shooting it.  This is reported from Europe, so there is a language barrier as English is all I know.

I saw something on a Google translated version of a forum, but some of the words were not translated, which made hard to figure out.  The valve seems to be one problem.  Maybe.

I asked him to specify and I will post what he says when I hear back.

the schrader valve can leak but the cap screw has an 0-ring seal so unless there is a catastrophic leak it should really only be a minor inconvenience and the valve is threaded into the gas spring and easily replaced. The gas spring is intended to be rebuilt and the seal kit is readily available

These are neat rifles. Only down side I see is the weight. It shoots like a howitzer and weighs almost as much ;) super for hunting medium sized game as well as other unmentionable pests. Other than that the RX/HW 90 gas Rams are pretty much worry free air rifles. One thing to remember, if your rifles gas ram is fully charged you should avoid light weight pellets as this will resemble dry firing and end up frying your pistons' main seal. These are hunting rifles that need to be shot with pellets appropriate for their power setting. Happy shooting.
PS: To avoid the Schrader valve from leaking, an occasional drop of air tool oil will keep the rubber parts of the  valvel soft and supple and not dry out causing a leak.  it's a good idea to do this before charging the ram after a maintainence check of the internals or a complete rebuild overhaul.

Great heads up, I didn't know that was the best solution for that problem . Thanks for the timely tip

HW makes the Beeman RX for Beeman. HW90=Beeman RX

like some have said here, the gas ram is, without doubt, the best "springer" out there, and it IS a scope killer, IF the wrong scope and mount(s) are  utilized.

adjustable "Power"...ez to work on...accurate.

I use a divers, silicone "O" ring lube, on the Schrader valve occasionally.

I've owned mine since 1989-1990 and I may purchase another in 22 cal soon.

make sure you get a pump with it (or a way to recharge the ram should you empty it) or you'll have a 10 pound paperweight.

I have the Beeman RX in 177 cal. One thing that has not been mentioned yet is these need to be cocked/shot regularly or one of it's O-rings can stick inside causing problems. If cycled at least a couple times a year they are a great powerplant and are very accurate for the power they produce. You can also fill them with nitrogen instead of air if you wish.

I have heard this before for this gun, so if this is true how does the HW 90 handle shooting the lighter 177 and 20 caliber pellets? Do they remove pressure at the factory or do those calibers have problems with premature failing seals? or is the" must shoot heavier pellets" just a myth?

 ;D I let a little air out of my RX2 and even though still shooting 910 fps for 20 FPE all that has happened is the rifle is easier to cock and the recoil is less harsh

I have previously owned a RX-2 and HW90 and made the mistake of selling them.  I recently picked up an RX-2 .22, which I have pressure tuned.  I like it so much a I have .177 on the way to play with.  I couldn't recommend them more.  But don't try to make it the biggest, badest, MF magnum you can.  Adjust the pressure to find the sweet spot and then, IMHO, you will have a rifle no springer can touch!  The experiment is below:

 ;D ::) I own several very nice PCP rifles and within the practical limits of under 50 yards the RX2 is in the same accuracy league Yes it is a springer but without the spring torque in the shot cycle this rifle (RX2  .20) is as easy to shoot accurately once you get comfortable with this lady ;)

I also have a couple of very nice PCPs and couldn't agree with you more.  Tuning is the key.
