Bob, I dismantled my own 21 and used some fine wet/dry on the bolt to reduce the friction. I also applied some "Dri-Slide" and can confirm that the loading process on mine is far better than the one on that Jones blokes. Its just a pity that I cant shoot mine quite as accurately as he seems to be able to shoot his. I reckon he has devised a homing device for his pellets, as try as I might, I can never approach his scores.
