    I have read all your comments and i'm in no doubt that this is a superb hunting tool.It's just I'm so puzzled at the amount which are for sale secondhand?My Air Arms S410 Custom Shop .177 with Logun Silencer takes some beating in accuracy and quietness!

    I think that some people find the full-length version a bit too heavy at the forend.
    The carbine is better, but still heavier than the AAS410.
    But the HW is solidly built. Mine have shrugged-off knocks that would have upset a S410 (I know because I've owned S410's before that couldn't take much of a knock without losing zero - I replaced them with HW100K's).
    The HW also has a regulating mechanism, which means that you don't need to look for the pressure sweet spot.

    Just wondering how much truth is in the talked about faults with these HW100's or is it just a myth or only effects the odd one or two

    Three sections that I read about and crop up from time to time are:

    1) Power tends too creep up over time/bedding in

    2) Barrel Band temperature sensitive causing Accuracy issues

    3) Two piece Action Requiring a One piece mount this on a PCP to strengthen the block up to iron out Magazine fitment fault and Scope accuracy.

    I've owned two HW100 Karbines and none of them had any of the above faults The only disapointment I had was poor shot counts but thats part of the terriotary with such a small air cylinder.

    Power will tend to creep up on many new guns as they "bed in". The worst stories of creep were particularly bad when Hull used to set them to 11.4 with Superdome, which are a much less efficient pellet than JSB/AA or Logun. Set your average HW100 to 11.4 with Superdome and I'll bet that I can make nearly all of them go above the limit by choosing a more suitable pellet.

    The barrel band is a problem on every make of gun that I've used. It is not unique to the HW100. I initially used mine without the band (it's a barrel as strong as that used to cock the 18ftlb+ HW80's!) but now I use the band to support the cylinder, but I've removed the O ring from the part that the barrel passes through.

    The two-piece action moving is a myth, unless the bolts aren't up tight. In my experience, those bolts are always very tight. There are also several dowel-like pieces and a step, that interlock the two halves.
    I use a one-piece mount, but I don't think it's necessary.

    Cheers Fluff some good info there to quash those myths

    Out of interest do you know what pellets HC are using now to set them up on?

    I guess the one piece mount is also a personal preference for many shooters prefering this mount over 2 piece etc and a bonus that the HW100 action actualy allows one to be fitted due to the magazine not being in the way as with most Multishot PCP's.

    In 2003-2005, they seemed to use Superdome.
    In 2006-2007, they used H&N FTT, which are usually much more efficient, but still not as efficient as the Penetrators, JSB/Daystate Heavies and the like.
    Nowadays, I think they're using HW FT Special, which are fairly similar to - but slightly heavier and better than - the FTT.

    In my experience, those pellets are fairly good for power-setting the .22 versions, but in the .177's, FTT/HW-FTS are not much above average power and often out-powered by the heavies, so the heavies can run close to the limit.

    All guns can have issues, but if you have an HW100 in perfect working order (most are) then it's a tough act to beat imo.

    Never had issues with the two piece action, in fact the only issue i had was my .22 went a little low on power, a good de-grease and clean of some of the internals sorted it out straight away.
    Imo, HC put too much grease in the mechanisms, the grease thickens in the cold, and slows the way they operate.

    I chrono mine on a regular basis, and it's unbelievable how consistant the readings are.

    Definately keepers!

    Agreed. That grease really holds them back, but it's easy enough to get most of it off, even with the AT version.

    I've tuned mine, which involved a de-grease and they have no power fluctuation - just a steady 11.25ftlb all-year-round, from freezing mid-winter through to scorching summer.

    dont know what you mean by silent ? mine and my shooting buddies are both noisey on the action but great otherwise

    how have you made them silent

    It can depend on how they've been set up at the factory. Like all guns, you get some that are better than others.
    The noisiest one's will tend to be smaller calibre, shorter barrel and the one's with lower shot counts than average.

    Ever since my thread earlier this year entitled; "Do I need a HW100!?!" I've loved every minute of ownership

    In terms of the sales stuff, you'll always see loads for sale, as they are incredibly popular. Think of it as a 3 Series BM, you see stacks in the classifieds because there are stacks on the road, not due to any inherent fault.

    Faults are funny things though, and it's easy to get wound up in the moment - just bear in mind that nobody ever posts "HW100 working fine today, just like yesterday" - doesn't make for the most interesting thread

    Interesting thread this, I do have a soft spot for the HW100, and kuro good point bud

    Fluff, something else I've always wondered is the HW100 actualy 100% Regulated or is it semi regulated? I've heard so many people say this and that etc, and to be honest semi regged what the heck does that mean

    I bought an OI ring for just the cylinder

    Totally agree, I have 2 piece mounts on mine but that block is going no where. The bolts through the block are certainly not feeble and once tightened is solid. I hear people quoting some strange 'paranormal' activity in this area but I just chuckle and usually keep quiet, after all smile is most welcome
    +1
    I bought a second hand HW100 pre AT and Pre quick-fill about 2 years ago.
    Its spot on, pellet on pellet.
    I don't use it much now as mostly take the HMR out in the fields hunting.
    Its a superb garden gun, (I have a large garden) taking out the occasional morning magpie.
    The reloading mechanism is faultless, the best of any rifle and impossible to double load
    (well unless your dumb enough to force it be manually by removing the mag and inserting it again with pellet)
    The 2 stage trigger again is superb, Weihrauch never disappoint here.
    The cocking lever is effortless and quick without (tugging at a bolt)
    Its whisper quiet.
    My HW100 is a cracking rifle and a definitely keeper.

    The only gripe I would have is FAC area. I wish the FAC version had similar specs to the Rapid.

    I get slated for this but its my opinion.
    In sub 12ft/lbs you can't beat a HW100 its perfect and ticks all the boxes.
    Only FAC would I touch a Rapid (because then you need high power and shot count)

    It has a mechanism that equalises the velocity from shot-to-shot, so yes, as far as I'm concerned, it has a regulator, even if the reg design is unconventional by being external to the air cylinder.

    Here's a full-fill shot-string from my .177K taken during my tuning process (s/n 1909043, 11.1ftlb average energy across the whole charge), using unsorted JSB's/AA's (with known variation of 8.2-8.7gn, which accounts for most of the shot-to-shot ft/sec variation if you do the maths).

    Wow thats impressive Fluff, all those shots from a Karbine thats about double the norm over a standard Karbine, even Weihrauch have it listed on there website as 50 shots in .177K guise. thats some nice tuning

    I notice you have a .22 HW100 as well, I've never shot the .22 HW100 before and without wishing to get in to a calibre debate as its horses for courses etc how do you find the .22 flavoured HW100 Fluff?
