HW/Weihrauch Weihrauch barrel idioscyncrosies explained

[Mycapt65]

On my new HW95n in .22, when I pushed a pellet through the breach and on through the barrel. I found the breach to be snug but not tight. And you can feel the pellet clear the breach and enter the barrel. The barrel fit is less snug than the breach. But nice and consistent drag until about 2in before the choke. Then I felt a slight but noticeable drop on needed pressure to to push it forward. And the choke is about as tight as the breach. Maybe a little tighter.
I polished the barrel and the push through the barrel is now consistent from breach to choke.

I’m pretty new to air gunning. So I’m just offering up what my experience is with my only HW rifle.
I’m currently running my 1st tin of 500 through it. I can update accuracy findings at that point maybe.

What you found is the normal pattern I was talking about in opening post. Thank you for your feedback. I hope you get years of enjoyment from it.

Be well

Thanks. Depending on the JM kit I would think so. Dave Deerhunter gets 17 fpe with a JM kit and a Vortek seal. My 20 cal R9 and your 98 have JM kits and Vortek seals and they make close to 16 without pushing for power. In 22 a 95 family gun should probably make 16 with a good factory seal. And of course a good barrel.

My .22 is also right at 14 FPE. It does have a large ES of 41. I'm hoping the OEM seal is my problem. Guess I should push a pellet through it and see what it feels like. Almost ordered a .20 cal. barrel but decided I want to try and get this .22 working.

Out of curiosity do you retain the .22 bore with the .20 barrel. Or you replace both?

Not sure what the question is.

Not sure what the question is.

You said you have a .22 that you are thinking of putting a .20 cal barrel on.

My question is: does the new barrel get installed with a new .20 cal Breach to match the new .20 cal barrel.

Weihrauch barrels come with the breech block, chisel detent assembly and breech seal, it is a complete assembly, sorry for the confusion.

Good to know. I’m considering a.20 barrel for mine. Just to have options lol.
Thanks for the information.

You will need to switch over or buy another cocking linkage and rivet. I usually buy a new linkage and rivet with each barrel. It makes swapping easier and they're not that expensive.
