Another member "breakfastchef" provided this link to some information on hold and shooting spring airguns in another thread. Might be something helpful in there for you. I got my first spring gun and it is a little different than the powder burners I'm more familiar with. Good Luck.http://www.airrifle.co.za/library/AdrianV's%20Art%20of%20Springer%20Shooting.pdf
