this is just an explanation of why!!!!!
there is nothing that comes out of a box that is perfect.
women when looked at look perfect but once you get married and open the box you find that you have fine tune to get the best performance.
when i go out to a mine to demo some equipment and it works first time i get worried because 99% of the time there are little hick ups.
the Walther is no exseption, out the box it was prommising but after a phew shoots it was apparent that it needed some fine tuneing, yes it took 3 attempts but it is spot on now.
just like jasons S400 it is not an out the box rifle, he has had his hands on it fine tuning it.
the person who tells me that his equipment is perfect out the box it just telling lies.
i await your comments
