It should have been a simple swap turned a little confusing but got there in the end.

Good work! 👏😃👍 Some times these rifles make us want to pull our hair out, lol. 😆👍

Yep, thankfully the 80 is pretty easy to work on

Chopped off my 500mm barrel down to 250mm think that’s about 9.75” needed moderating because it was hard to cock. Better all round, snappier to shoot and more accurate over 35 yards. Just easier and more enjoyable to shoot.

Looking forward to you putting this over the chrono.

Fingers crossed its not too bad if at all, I've got some light and heavy pellets to test

awesome that you got it to work

Why oh why it didn't work 1st time of asking is beyond me 😆

@@keith6930 I think the spring must be slightly larger

Could be the cocking shoe catching on the stock.you will see a mark on the inside of the stock if it is

@keith6930 Ай бұрын

That's could be worth a look. It's coming apart again for a fettle and lube up anyways. The cocking shoe not aligned or catching could be the problem as it then cocked and worked fine later. Good call

@carllarge-u2k Ай бұрын

@@keith6930 I no if you change the earlier type cocking shoe on older guns to the newer version you have to remove a little bit of wood from the stock for it to travel just a little further and maybe then you changed the barrel the cocking arm hole is a little further back causing the problem.good luck with it

@@carllarge-u2k I had another look this morning and it's amazing with a bit of lube and fettle and it's now putting out numbers I thought it would, well over the limit with both heavy and light pellets 😂 Some experimentation and a HW97 spring and it's running mid 10s instead of 16s!

@carllarge-u2k Ай бұрын

Glad to hear you got it working ok.ive not tried it myself but i have seen on the forums that a titan 10 plus from Knibbs works well in the hw80.comments are that it’s much easier to cock but still just under the legal limit

@@keith6930 I had the same problem on a HW90. After removing the stock for a regular cleaning, I put the stock back and it wouldn't cock. At the end, all it took was to release some tension on the rear guard screw. And indeed it was the cocking shoe catching on the stock.

Changing the barrel how the rifle cocks or locks up the length of the barrel makes no difference to the preload all.the preload does is increase or decrease the power accordingly

@keith6930 Ай бұрын

Agree. I've changed plenty of springs and found them to need altering to allow them to cock. This was what I had going through my mind and sent me a little mad for a few hours going back and forth with it. Went back to the original spring and it cocked 1st time!!! Why this didn't happen hours before is beyond me? Stressed for. I reason other than my shear incompetence I suppose 😆

@phillipward4862 Ай бұрын

@@keith6930 that's the beauty of springers some times they can drive you to insanity for no apparent reason. Just out of interest what power are you getting with the 22 spring I can imagine it would be quite low. ?

@bobthebarsteward Ай бұрын

I've heard the HW80 barrel also fits the HW90, something else to try out.

@keith6930 Ай бұрын

The pivot point might need changing, I think the early and later ones on the 90 are different?

@leecolclough2492 Ай бұрын

Breach cocking link hole different place aswell as mk2 cylinder mk3 plus barrel ?

@keith6930 Ай бұрын

Could be any permutation or combo, who knows. Hopefully I'll get some pellets down range and see if it was all worthwhile

@keith6930 Ай бұрын

It will be, a bit of teething problems as needs some lube fettle and a longer spring and should be good to go

@rapalaron6348 Ай бұрын

Hi mate! If the cocking arm is the same and the breech length from the .25 is the same as the one from the .22 and holes match it should fit. The spring has nothing to do with it. The .25 needs the most powerful spring you have there. Cheers!

Recently i was so curious to know if the air transfer port is also different in any air rifle same model but different caliber but unfortunately no one did answered my question i just want to know i there's any different in air transfer port size of same model air rifles EXAMPLE ( Hatsan 125 in .177 and .22)

@keith6930 Ай бұрын

I don't know why I went down a little rabbit hole of trying to fix it when it shouldn't have been that hard. But hey ho? What's a couple of hours faffing anyways 😆

@keith6930 Ай бұрын

There is something about transfer port size and power but I can't remember what it is exactly. Difference in TP between calibre, I don't believe so

@rapalaron6348 Ай бұрын

@@keith6930 Hi Keith! I can take the diameter from the transfer port from my factory HW80K in .25 if you want. Maybe there is no difference at all, but when it is wider and you should drill it out than there is no probably way back to the .22 barrel. I've still the opinion that a HW80 in .25cal should have a fac spring to get out the performance it is made for and you'll need the moderator on it for easier cocking. If the transfer port has the same diameter it would be great and you can try and swap everything you like 😁I have no second HW80 to compare with. Just tell me and i will measure for you... Cheers mate!

@rapalaron6348 Ай бұрын

@@Double-xposure Would be good if there is no difference on transfer port diameter but a HW80 in .25 cal needs in my opinion a fac spring to get out it's potentials where the is made for. I think the .22 barrel with 12fp-lb spring will be the better choice.
