So I set up at the range yesterday. Placed 700p on bench. Set up and notices a silver steel ball on the bench. Thought who would shoot a BB gun here or maybe buckshot. Looked too small for a bb. Thought nothing of it and carried on shooting. About 25 rounds in notices the spring sitting on my gloves on the bench under the action. It all came together as I have spent some time tuning that trigger. The ball was long gone still have the spring and still shot normally without it. Tested trigger pull when I got home and still pulled just under 2lbs. I looked over the diagram and since nothing seemed to change does it need to be there?
