I was sad to see the original thread deleted, as it was very interesting, and I wanted to hear more about Harry's claims. I realise he may have stepped out of line, but plenty of others were insulting from the off, but he remained pretty civil despite it all. I feel that his experiments could be valuable to all shooters, as it's only by pushing the envelope that things change for the better. Who knows, maybe his local weather conditions are the key to this type of shooting. There's a world of difference between this draughty, damp island and his. However, we won't know if his location is the key, not on here anyway. PS Terry, when did you try for the 100 yard groups, and what pellets were you using?
