    My local club was Tree Tops, but now closed. I'm trying to get into Quarry Hunters, but that is taking some time and even if I do get there, I can't just rock up and ask to try some guys gun. Infact, I can't just turn up cold to any club and ask to try a gun, it's just not the done thing.

    Every shop I've asked so far say no to trying before buying. The one I bought the LGU from said to go to Tondu (north of Cardiff) to try a TX and just ask, that was their answer rather than helping a customer standing at the counter. You'd never buy a car with out test driving it or buy a TV without seeing the picture, yet you have to buy a gun without shooting it, it's very odd.

    I think most shops are just there to shift boxes, the shop I bought the LGU from were utterly clueless to differing recoil between the LGU and TX when I asked today. The first guy on the phone I asked said he thought he could help, but didn't know! I said you either know about recoil or not! He got somebody else to talk to me. I think people find me hard work, but I'm really not, if you know what your talking about, I'm easy. If you don't know and try to fob me off, I'm very hard work, but that always seems to be 'my' fault when a sales guy is clueless. Must be this age of denial we live in!

    This is why I was hoping to meet somebody here sympathetic to my issue and happy to try my LGU or let me shoot their gun for 10 minutes. I really want the best shooting gun I can get before the bringer bash, not that it matters, but I'd just like it by then. I guess I could just wait and ask at the bash, but that's weeks away and time wasted shooting.

    Maybe I'll just buy a TX and sell the losing gun at the Boing Bash?
    Both guns will be mint and new, so should simply fly away!
    I'm with TonyL on this one in saying persevere with your LGU as is for the time being for a number of reasons, unless you really do just want to buy all the options and just flog what you don't like, or indeed keep by way of variation.
    Nowt wrong with that if that's what floats your boat. I've done it myself before now - it's just not conducive to a healthy wallet!

    However, at the moment you are chasing a degree of perfection that even you haven't really defined yet, without really knowing how all the different options perform.

    Some of the "uber-tinkerers" that attend the Bash have been though iterations of tune that must number into double figures for the same type of gun trying to get the perfect shot cycle, and even then what one person thinks is perfect will be imperfect in someone else's opinion. With the best will in the world, if you are seeking the nth degree, holy grail of air rifle, you aren't just going to plug in "Gun X + Tune Y = My Perfect Rifle" without some heavy practical research along the way. It's simply not going to happen straight off the bat no matter how much effort you put into it, nor for that matter how good you are at it; it will be an ongoing process and even after you think you have it sussed you may well still change your mind.

    In fairness to the gun shop that you called and asked about the difference in recoil, in what quantitive terms would you expect him to accurately describe over the phone such a subjective issue? It wouldn't have been much use him saying just one had more or less recoil than the other when they are so similar.

    On the try before you buy, don't forget that if it's a new gun you're talking about, few shops are going to be willing to start unboxing and allowing you to shoot brand new multiple rifles unless they have an actual demo or 2nd hand one of each - after all they still have to sell them and someone will be expecting a new gun, not one that a random customer has had a play with and put back in the box to be sold as new.
    Also if brand new they won't have a scope fitted so again won't be fully representative of how a scoped-up one will shoot, not least because even irrespective of the scope spec itself, it will affect the overall weight and balance of the gun.

    If you hold fire until you actually get to the Bash it will give you a proper chance to see other variations, and the guys there are usually more than willing to give each other chance to experience what their particular rifle is like, not to mention being able to compare side by side with yours: You don't need to have "The Best" rifle by the time you go because A) that's not the point of the bash, and B) it won't be!

    For what it's worth I've tried a few of the different iterations, as will have many others on here, and to that end , in the fixed barrel underlever /sidelever springer vein alone I still own 3 97's, a 77, a Tx200HC, a prosport, an LGU and an original 52. I am pretty sure I'm not the only one on here who has a similar assortment, and I know there are some pretty exotic variations with reduced bore, reduced stroke, lightened pistons, titanium pistons, alloy pistons, buttoned pistons, skirtless pistons, o-ring heads, different seals etc etc.

    With all those variations you will still get differences of opinion as to which is best depending on personal taste.
    Personally my favourite is currently a particular tuned 97 (rather ironically the first 97 that I bought, since modded, but not extensively). l also really like my TX, and the LGU is good too.
    You will find fans of all 3 who will place their order of preference in every possible combination, and none of us are either completely right or wrong.

    Just my 2 penn'orth...

    ^^^ Taz made some very valid points there. Tony L and others have given some good advice too.
    I would add one or two myself.
    Shoot the Walther a lot!
    Find the best pellet for the barrel. Put a tin or three of pellets through it. By then it will be running in (if not perfectly run in it should be well on the way). The recoil and grouping will improve as the gun runs in. You will adapt to the feel and develop the hold and your accuracy with the gun will improve as your gun smooths out its firing cycle. Check you are getting consistent MV's, if you are then don't tune it/detune it or mess about with it other than adjusting sights, trigger and hold if you need to.
    When you have shot a few hundred pellets (at least 500) it may be worth re-testing your grouping with some of the pellets you may have rejected initially as a gun can run in to like a pellet it initially did not.
    When you've got the gun fully run in and have adapted your hold, stance and technique to get the best you can from it then compare it to another gun but in my opinion it will take a good session to decide if another gun is actually better/worse than yours, a simple 10 pellet group won't tell you much!
    I have watched people change gun after gun in the search for "perfection", trying however many tuning kits and scopes and springs and lubes with each new gun and never actually getting truly happy with any of them, often going back to "I wish I still had my old ... I had years ago, it was excellent, wish I'd never sold it, I'd buy another today..." etc.
    Take time to learn the gun, no matter how good a shooter you think you are it takes time to get settled into a new gun. I have a couple of very old HW80's that I cling on to, I have had many other springers over the decades and keep going back to them. Not many people would call them a competitive target gun but I'd be happy to take one out for a HFT competition tomorrow, at least I wouldn't have to gain a new "muscle memory" for a new gun (but then again I'm well rusty!)
    BSA Super10 addict, other BSA's inc GoldstarSE, Original (Diana) Mod75's, Diana Mod5, HW80's, SAM 11K... All sorted!

    Hi there just wondering if you have seen the tube vid's done by shooting at dawn https://www.youtube.com/watch?v=jV6RAO1i1A0&t=1s
    or read the articles written by Hector https://www.ctcustomairguns.com/hect...he-walther-lgu he has done a fair bit of work on the LGU. Just a quick question you say that you opened the port on it but did you check the power after just wondering because my .22 as you say shot up quite a bit and needed 1 1/2 coils off to get it right the rifle now shoots great, I have not got a TX to compare it with but its a lot nicer than my Walther Century 0.22. I think you don't see kits out there as they are great already just a bit heavy, why spend all that on a rifle then have to spend out again to fix it to how it should be. All the best Graham.

    Hi,
    I am considering doing the same to my .22 LGU so could you tell me what size you opened the transfer port to and the shortened length of the mainspring.
    What are the chrono readings now after the modification?
    I have ordered a new cylinder and mainspring just in case I cock it up.
    Cheers

    Very good thinking. While you are there, you might like to try my Nick G tuned LGU -very quick, no recoil, and pellet on pellet.

    Hi Sunbeam,

    I have the LGV (the break barrel version). I find it very smooth and accurate but note like you that it has some recoil. Some of this is or rather seems to be twist (torque from the spring?). Now it is out of warranty I intend to strip it polish the spring ends and remind to see if that helps.

    I am also thinking of adding weight at the muzzle to see if that reduces any muzzle flip. This latter option is a cheap, easy and reversible way to see what happens which might be worth trying on your LGU?
    Cheers Rich.

    I have some nicely tuned guns,but I have tried Vernal's Lgu at the last Bash and it is the mildest fireing springer I have shot yet..

    Just as an update on behalf of Sunbeam, he ended up getting a TX and sold the LGU, I seem to remember.

    And yes, sir, your LGU has a most dignified demeanour.

    Pure physics dictates that you will always have recoil in a spring (or gas) piston powerplant. However, this can be reduced in many ways, by tweaking the internals and/or increasing weight and altering the weight distribution to give more favourable movement characteristics.

    I've mentioned a few times on here of one particular LGV that starkly demonstrated the twist you mention. I also opined at the time that I believe this phenomenon to be more illustrated in guns with rotating pistons. In all fairness, that rifle shot beautifully. Very little perceived recoil and a very quiet action. Shooting at a 20 yards indoor club range with a high mag scope and the twisting effect was very prominent. Certainly not knocking it as it was accurate and forgiving to shoot. Making sure those spring ends are square and true, polished and with the addition of some polished steel washers, or Delrin items, will hopefully reduce this.

    Just a note.
    Pellet weight and size can make a massive difference to felt recoil. Too loose and light may make it slam, to heavy and tight may make piston bounce.

    If you're using mid weight pellets, I'd suggest trying some 7.9g express and vice versa if you currently use lightweights.

    I'd avoid tinkering until you've explored this.

    If you feel you must experiment, I'd start off with taking a little bit off the spring length and see whether it maintains current power. Keep cutting until you see power start to fall. Any lost power can easily be regained with a spacer.

    I'd be surpised if the LGU/V were unlike any other new guns which all seem to be oversprung.
    some rifles, not too many but definitely not enough
