Hey,thank you for the replies.
It's an Webley AGS Camo rifle. 2nd hand. With a excelvan 3-9x56eg scope. It's spring loaded and I'm using Bisley Pest Control 5.5 mm (.22) and Spitfires .22 pellets.
Pest shooting I'm using it for, mainly standing up or sometimes resting on a fence post.
I was looking at getting some baracuda hunter extreme pellets or rabbit magnum II
As did wonder if was my pellets but one shot is fine the second seems to go else where. My dad's air rifle seems better and I think that's older then me lol
