    I`d like a shorter barrel for a Diana 54 Airking. Who does barrel shortening and re-crowning or is it possible to buy a new Diana barrel ? Anything less than the present 21" would make the gun a lot more usable and it might fit one of my gun bags:).

    cheers .........Andy

    Why don't you have a go at shortening it yourself ?
    If your not happy with the results, then pay someone else to take 1/4" off the barrel.

    Careful what ideas you put in his head. Its a bitch to weld the choked part of the barrel back on once you've cut it off :rolleyes:

    Yeah , I`m actually thinking of someone like Steve Pope or someone experienced at this sort of thing. I shot it today with the 21" barrel and its very accurate , if just a bit on the unwieldy and scarry side. I don`t think its the original barrel unless it came off a US market gun (also its 18.8 mm dia).
    Makes a great benchrest springer due to it being recoiless, by the way its .177. Could do with a re-blue after any work.
    Cheers Don , I`ll give him a call.

    Do they cut off the breach end then? Because every barrel shortening job I've ever seen (including the two I did myself) where all cut off the dangerous end!
    And the two HW80's that I chopped lost their chokes and grouped really well afterwards.

    Atb,

    Choke?

    You'll find that springer barrels aren't "choked" so can be shortened from the muzzle end. It's a common myth that HW80 and other HW springer barrels are choked, I'm afraid they aren't!

    Why does it get tighter at the last inch or so when pulling a cleaning felt through or pushing a pellet through from the breech then?:confused::)

    My understanding is that HW where choked, but only as a by-product of crimping the foresight rail and not choked specifically. Either way (choked or not) I cut about 5 inches off of two different HW80's and recrowned them both successfully. Both grouped as well after, as they did before.

    Atb,

    Alec.

    I've heard/read the same thing, but neither my 77K or 97K barrels have the foresight grooves... all i know is that when i use my VFG cleaning rod with the felt pellets there's a noticeable tightening when the felt nears the end of the barrel, and it's definitely not at the actual crown but someway's inside the barrel. It's the same when pushing a pellet through from the breech with a rod too... So, if it ain't choke, and there's no exterior machining work done to this section of the barrel... what is it?:confused::)

    Snap, my HW98 had was very tight towards the end when using a pull through, no external grooves either.

    Perhaps you just need a Mars bar or something half way along to give you the energy for that final last pull. Daniels was saying something about it the other day when he and tool were talking about rodding and pulling. Mentioned something about choking as well...

    Jealous the pair of you !

    It's all about keeping the Mars bar at the right angle when you insert it to stop choking.

    Always keep at tight grip of your barrel when rodding & pulling, be careful that KY on your pellets doesn't work but is good for extracting a fat lad from a shower cubicle !
