Another couple of tips-

To reduce the cocking force don't be scared to wind out the hammer spring preload plug by a couple of turns.

It makes NO difference to muzzle velocity according to my chrono, 570fps shot after shot, but it does lighten the cocking pull.

Also, when loading the magazine turn it by one pellet 'bay' before loading, so load one less pellet. I have found that if you fill it , when you try to load the last shot the bolt will not go all the way forwards. So you remove the magazine only to find (by accident) that there is a pellet loaded this has happened to me several times. I fully expect I'm doing something wrong but to be safe I load one less pellet and the problem goes away.

Have fun!
