Well, I like this rifle very much but haven't taken it out that often as my HW100 is my go-to gun.

Thing is, I took it with me yesterday for a spot of pigeon shooting and when I pulled the trigger it made a loud bang but nothing shot out of the barrel! I seem to remember this happening before and wondered if I'm not pulling back the bolt firmly enough? Maybe I draw it back just enough to allow the air to come through but not strong enough to rotate the mag?

Could I have my mag too tight or not tight enough? Or maybe the little brass thing that sits under the mag needs a tweak?

Any help would be greatly appreciated.

Thanks in anticipation ..
