Guys, I have been working on several HW100's over the years and based on the quality and reliability I decided to buy one for myself. my first was a pretty beat up spares or repair off Freeads. after much time and effort I got this old girl shooting beautifully, close to 100 shots at 11,7ft.lbs. no spike as it cam off the reg. Then the problems started accuracy. i tried many different pellets and after re-crowning, cleaning and re-leading now have a reasonable barrel that will consistently group at 20mm groups at 40 yards, not good enough. So I then bought a one year old action and a new CS700 stock and recommenced testing with this one, almost same results as the first. I then cleaned and re-leaded this barrel, low and behold sub 10mm groups at 40 yards with a variety of pellets. Happy Bunny. Very different to the first barrel? Now upon speaking to various people, there are definitely good and bad barrels, it doesn't matter if its, Anschultz, Weihrauch, BSA or Lothar Walther . My question is does anyone know of a "Match Grade" barrel for the HW100? by the way my latest testing has been using a single shot loader, that opens up a whole new discussion point comparing to magazines.
