Like the title says, is it possible to change the .177 cal. barrel on a HW50s with a .22 cal. Is it even possible to buy the replacement barrel alone? If the answer is yes to these questions, are there any other altercations needed to make the change work? Why the change you ask? I find the .177 lacking in knock down power at longer distances.

HW/Weihrauch Barrel interchangeability

Yes. The gun needs to be disassembled to remove the barrel. The cocking linkage will need to be moved to the new barrel. I have bought barrels from Chambers, here is the HW50 .22.

You need a barrel, the cocking arm, and a new rivet. You can swap the older cocking arm over but I would just create a whole new assembly so swapping them is quick and painless

That's sounds like the way to go, Although I don't see myself swapping it back but still may be if it was made simple enough I wouldn't rule it out. Thanks

True that, I don't see myself going back to the .177 cal so that is what I will be doing if I can get this done. I'm in contact with T.W. Chambers now, waiting for an answer to my questions about the purchase. Thanks to all who helped me with this.

So....I'm in the process of rounding up a new .22 cal barrel, a new cocking arm and rivet to replace the .177 on my HW50s Thanks for the help already received with this.
However I have one more question before I pull the trigger and have these parts shipped here from the UK.
Will I need to alter/enlarge the orifice from the compression chamber to make this swap effective as a .22 cal? or will the rifle do as it would if I'd have purchased it as a .22 cal. to begin with? Thanks for any help answering this question.

I kinda figured the fps difference in .177 and the .22 kinda shows the only difference is the barrel .. you take a good hit going .22 in a hw.

I just replaced my HW50 barrel. Ordered from Chambers on their web site, Received in about 5 days. It was in customs, in New York, for 2 days. You will get the barrel mounted in receiver, the wedge lock and seal, also installed. Remove bolt holding receiver, unlatch cocking arm, drive pin out. Put cocking arm in new barrel/receiver, drive pin in, reassemble gun, clean barrel, mine had a LOT of brown rust looking stuff in barrel. Shoot and enjoy. Don

Brown rust lookin stuff is anti corrosion. I just cleaned a brand new 22 cal 50 sent to me for a tune.

Thanks, l wasn't sure if it was rust or some anti corrosion from HW. Sure was a pain to remove. Don
