    Choice of two

    One of the best club shooters in the south west uses a Rotex , I don`t know what discipline he shoots but he is in the medals. I also have a target ( but not from him ) shot at over 40 meters to do a pellet test and with the exception of the odd flyer the groupings are easily covered by a 5p coin. I am not knocking the BSA at all but the Walther is regulated , as accurate as most would need and comfortable to hold.
  2. They shoot above there price that`s for sure, some of the barrels could do with opening a little at the the breech to assist with pellet feed but to be fair most people with modest Dremel skills can do this. You can pay twice as much and still have actions loose in stocks so its no big deal it just means the person who machined the stock took a fraction more out than would have been ideal.
  3. I`ve come across a few that a washer has fixed, in all fairness a cheap gun is cheap for a reason.
  4. The screws are probably too long and bottoming out in the threads leaving the stock loose, try removing one of the fixing screws and putting a thin washer underneath it before putting it back in.

  6. Copied from a previous post I made, the description is a little crude but it gets the basic point over. The reason for that is when the hammer hits the valve for it to open it has to push against the weight (pressure ) of the air in the cylinder which is forcing it closed. As the pressure drops the valve can open a little more or for a little longer which allows a little more air into the barrel. A great deal of design goes into the valve design to help it "regulate" the air flow, this is why a regulator improves things because the pressure on the valve is a constant.
  7. Motorola G4 Play Unlocked 16gb This is the wife`s phone and she has owned it from new, it has always been kept in a flip case and fitted with a glass screen protector. As can be seen it is in very good condition and comes boxed with the charger as shown in the photos. The phone has been factory reset so it is now good to go. £40 PayPal friends and family or bank transfer , it will be posted Royal Mail recorded delivery.
  8. NOKIA LUMIA 830 UNLOCKED I bought this a few years back to keep in the glove box in case of emergency, needless to say I have hardly used it. It comes with a bumper a flip case and the items shown in the photo. As can be seen the condition is very good and it works fine. I had it unlocked by Nokia so it is done correctly and has been re set to factory defaults so it is now ready for you to put your sim in and the settings. £30 PayPal friends and family or bank transfer , it will be posted Royal Mail recorded delivery.
  9. That is called PD (pupil distance), for most people the measurement is within a mill or so. There are various ways to get this measurement and this google link gives you some methods. https://www.google.co.uk/search?source=hp&ei=GBOoXuOyKMqWaKCkqYAI&q=how+to+measure+pd&oq=how+to+measure+pd&gs_lcp=CgZwc3ktYWIQAzICCAAyAggAMgIIADICCAAyAggAMgIIADICCAAyAggAMgIIADICCAA6BQgAEIMBUOACWOAlYLw0aABwAHgAgAH_AogBkBGSAQc5LjUuMS4ymAEAoAEBqgEHZ3dzLXdpeg&sclient=psy-ab&ved=0ahUKEwjjnozrgYvpAhVKCxoKHSBSCoAQ4dUDCAk&uact=5

    Haenel 303

    The vast majority of springs are over sized and require cutting, the end coil collapsing, grinding square and re tempereing. This process may be needed to be done several times before the power level of the gun is made to be under the legal limit. Apart from a Chronograph you will need a bench grinder a decent blow torch with a fine flame a spring compressor and other hand tools. The process could take from 30 minutes to over an hour depending on how many cuts are required and how many shots it takes to get things right.
