half n' half 8 Posted November 3, 2010 Report Share Posted November 3, 2010 he couldn't of changed the hammer spring without taking it out of the stock and if it was already pushing out 10ft lb he wouldn't need to. all that was needed was a small tweak on the existing spring to bring it closer to the legal limit of below 12ft lb.

pianoman 3,587 Posted November 3, 2010 Report Share Posted November 3, 2010 (edited) Hi Darren. What I don't get is where this so-called mainspring comes into play with a PCP mechanism . Unless it is acting as a return spring, keeping a regulator valve closed under tension or something? I'm in full agreement with Andy here, there's something fishy going on. But don't go trying to fix the thing yourself if you are not sure of what you're about. Is the rifle still under makers warranty or guarentee? I would certainly go seek the advice of a second, independant gunsmith, one who knows your rifle's inner workings and ask him about this mainspring's function and get an opinion on what's been going on with the other guy's diagnosis. If you are clued up, it will make it very hard for the other guy to bull**** you into parting with more cash than you need to. Never be afraid to ask a question you already know the answer to! Seems you've lost a pound or two in power and a whole lot more out of your wallet. I shoot spring rifles mate, I don't see one of these PCPs worth the money they cost to buy, when all they seem to do is break down in a hissy fit if a bit of dust gets inside them or you so much as look at them in a funny way. Pick up a nice springer and scope, tin of pellets, your shooting togs, rifleslip and your ready to go no matter what the weather. Hope it all works out for yu in the end mate.

ATB Simon I used to have a .177 TX200HC but it was heavy as hell and i hated it, then my mate cracked the cocking shoe by dry firing it, thus putting an end to my springer shooting days. i sold it for £100! and put the money towards the falcon, which im much happier with. the thought of having a trusty back-up springer is becoming tempting lately, not going shooting at all pains me more than paying for repairs etc.! Any suggestions for a compact, lightweight springer? I was thinking Lightning XL? Quote Link to post
pianoman 3,587 Posted November 4, 2010 Report Share Posted November 4, 2010 (edited) Hi Darren. Sorry to hear that one mate. The TX200 is a heavy rifle best used for static hide shooting from a prone or comfortably low-seated ground position. It's not a lightweight stalking rifle you can swing easilly and rapidly on a target of opportunity suddenly popping up unless you are really used to doing so. I love the two I have, but the weight is what I'm long-used to. Others will certainly hate it. The thing is,I want absolute accuracy and reliability from my rifle shooting on a hunting sortie, that's why I've never yet bought a PCP! Too damm fussy, overpriced temperemental faff. But, if a "Trusty" reliable lightweight springer is needed I'd absolutely seriously, positively, hand-on-heart honestly recommend you go take a close look at a Weihrauch HW95k in your favourite calibre. Hits like an ' with a lot less heft, it's got a really sweet handling character and very, very accurate. Once you get it bedded in it really smooths out, plus you have a Rekord trigger that's still the best in my book. I have a sub-12ft/lb .22 one I keep for ferrals, woodpidgeons, Squirrel and rat; and it's astonishing what it will group out to on a target session. H&N Field and Target Trophy are brilliant from it, Superdomes, Accupel and JSB Exact 5.51mm all perform well too. I've thought about adding a .177 one to my collection but, I'm getting a new HW77 ordered in a few days. It would outrange the BSA Lightning XL which, to be fair, is a fine little rifle for close 15mtr or less to medium-long range 30-35 yard shooting. I tried one on a decent test and found it a little too coarse and "snappy" on firing, but it produced decent groups out to 50 metres! The 95k has the accuracy to give you that extra 15 yards or more reach on a hunting sortie if you have the hold right. Not a cheap rifle but then, it doesn't deliver naff returns like one either . I'm not going to tell you how or what you spend your money on a gun Darren, but, if it were my cash, I know what I'd be spending it on, between the two discussed here mate. Give both a good try and see which one really fits your stature and reach well. That's the one you should really have buddy. Hope your PCP soon gets sorted without too much further pain too fella!

sam007 34 Posted November 11, 2010 Report Share Posted November 11, 2010 Darren I have a Falcon FN19 I have just done a refurbe on it The spring that is being talked about is the hammer spring (I on't know the technical terms) you can get at it by releasing the two bolts holding the stock on lift the breech mech, at the back of the breech is a cap which can be unscrewed the threaded tube (again forgive the lack of technical jargon)that this cap is fixed to can be be screwed in or out(this is the power adjuster) when a little allen screw on the side is undone.When taken fully out the hammer spring is inside the tube. I am sorry to be so long winded but the job takes an idiot like me about 10 minutes to do( it is pretty simple) Gareth Quote Link to post
craig33 10 Posted November 11, 2010 Report Share Posted November 11, 2010 darren im at rotherham 5 mins from meadowhell ill sort it you if you come over craig Quote Link to post
adesaxo31 0 Posted November 12, 2010 Report Share Posted November 12, 2010 The rifle could've been shooting under power if the rifle had just been filled because all unregged rifles have a power curve so it pays to learn where the sweet spot it like on an s400 I only fill it to 170 bar because that's where the curve goes flat untill about 110 bar then it dropps off atb ade Quote Link to post
