    This is interesting (well, I thought so)

    https://www.pyramydair.com/blog/2017...rifle-part-10/

    Velocity vs barrel length in a custom Crosman Ratcatcher type carbine, barrels varying from 7.5" to 24".

    Any thoughts from the technically-minded?

    Much as expected, surely ?

    For me, yes. But I don't claim to know how this stuff works in detail, I just shoot it. Most of the tech stuff here is beyond the understanding of my simple mind.

    New user name, Jon?

    i put a rabbitstopper 24inch barrel on my xt2250 kingratcatcher AS. i got the barrel off steve darrell at Sdcustoms and it took the power up from what the 14 inch barrel put out . i did no mods to the valve ,left it standard.


    8ftlbs with the 14 inch barrel if remember right and the rabbit stopper did 11 ftlbs or so .

    i dare say i would have got more power if i did do valve mods on it .

    i used to use the rifle for close range rabbits out to 25 yards on the farm.

    i ended up selling it with the 14 inch and 24 inch barrels to fund my gun cabinet . sold it for £100 on here .

    just had to watch the thin barrel as it would bend easy i would think. a shroud would maybe have been a good idea.

    Yep, interestung stuff, but totally as expected re barrel length / output when we're talking pneumatic and CO2.

    I like the underdog status that the Crosmans seem to enjoy over here and those accuracy results also come as no surprise, owning a couple of 2240s and 1377s (pistol and mini-carbine version of each).

    I often look in on the blog; some interesting stuff on there, and this is a good read.


    Loving the new user name, Jon. Your choice or a naughty mod?

    Nice one, Jon.

    I would expect your shed to be a finely honed and most well equipped one.
