So just took the X out the cupboard as a friend came over with his new x, its been in the rack for about a week since last used and was stored with over 100bar in and came out with 50bar.

Funny thing is my friends x which he just got has done the same twice this week only worst it had emptied completely.

We also just noticed while shooting it dropped alot for very few shots mine went from 220 to 190 for 1 magazine then 190 to 150 for the second.

When I used it the first time a month ago I got 9 mags from 240 to 100.

Since thats 2 here curious if anyone else has experience it, could it just be settling??

Stick a balloon on the end of the fill valve see if its leaking from there ?
 
Would suggest, with this issue you're having, to post on here Model (ie Sporter/KT - so we know if large or small cylinder) & Serial Number to see of a manufacturer pattern emerges, so others can keep an eye...etc
Will charge mine to 250 tonight and see how it fairs overnight but not noticed anything as yet...
 
There has been afew reports on FB sites about the newer x model's leaking, i did see a review on y tube about the dealers/rfd's having to fill the air tube fully before fitting it to the rifle or something like that :unsure:
Yeah I was told they need filling with the cylinder off for the first fill. It has had probably about 4-5 fills since I got it and this the first time I have noticed anything. Would have just thought seal but with the other new one having the same issue 🤷‍♂️

Its the sporter serial is 199somthing not near it right now the other one was also 199 but a couple hundred higher than mine.
 
The cylinder first charge must be carried out off the gun or the regulator can be knocked down to a couple of ftlb and it is a right faf to sort it. There is a warning on the outside of the box to do the off gun charge but nothing warning of what can happen if not done. It seem that even the dealers are not told the complete story.
 
My .177 Sporter, came pre-charged from Range and Country. See gauge and serial to log.
Will monitor over night.
There was no warning on the outside of my box as per Hull Cartridge/Weihrauch UK informed via YT/Their Instagram Page.
Rifle charged very very slowly and still same pressure after 20 mins (compensate for cool down change).

I WILL HOWEVER NOTE: my X cylinder guage initially read higher than my bottle guage when I first charged it, day after it was delivered (also a brand new bottle) but tonight, reads the same🤔

I've heard similar issues from a friend with the 100X launch edition. Disappointing when you've dropped £1440.
That's the dilemma with being an "early adopter".
On the plus side you get the latest kit.
On the negative side you sometimes end up being a guinea pig for the manufacturer to identify and iron out teething problems.
No doubt feedback will be going back to Weihrauch from dealers and HC etc so hopefully they can address this potential issue.
It's not a given though if you think about how long we've known about power drop problems with the HW110 range - with Weihrauch in denial for the first few years.

14+ hours ahead and a fraction pressure drop, but room it is in has dropped considerably in temp since last night...(Heating now on in house - no radiator in this room) Will continue to monitor.
But air loss is no where near what you are reporting.

UPDATE: 11:06 room now at average temp (18/19 degrees) and cylinder guage reads as per last night bang on 250 bar

It will always drop after pumping, especially from a dive tank as cylinder will increase in temp. As it cools to room temp, the contents will drop in pressure measurably.

Yes, bud, i understand this. Previous post i charged, monitored if any press drop after charging last night (20 mins later) and press was steady (charged very very slowly) so had a steady baseline pressure to monitor from.
 
For those suffering air loss, a couple of questions:
Where did you purchase your rifle from?
Did you have to 1st fill and fit the cylinder yourself or done by RFD?
Have you since removed the cylinder and refitted and charged again to see if issue continues?

This is very intriguing tbh....
