Patrick, I don't see (yet!) that you have any problem with the Werder. In fact, if you can get the shots inside 10" at 300 meters, that is very, very good with open sights and the short sight radius. The standard ISSF 300 meter target, as used by the BDMP and others, has a 10cm "10" with the rings at 5cm intervals, so all shots within 10" would translate as all shots well within the "8" ring. Just what is the problem - that shooting seems good to me!
