It’s strange how we sometimes forget the basics. There are varying schools of thought as to how often you should clean the barrel of your air gun. Some say never, others say after every tin of pellets (500 shots) fired through the gun and a dozen other opinions. What seems to be agreed upon is that if an accurate gun starts to lose that accuracy then you should clean the barrel.
I couldn’t remember when I last cleaned the Weihrauch HW75 and thought it would be a good idea to use my Napier cleaning kit to pull through some cleaning cloths. The first cloth came out quite dirty but the second one was almost pristine, so I stopped at 2. I then put 10 shots through the pistol to re-lead the barrel. I then put 5 shots on target.

I’m very pleased with the accuracy and consistency of the 75. I’m pretty sure any miss of the bullseye is “user error”.
