I'v been surprised at how much my rifles accuracy-performance varies using different pellets. At first I thought the shape had something to do with it. However, being able to test fire quite a few different types NSN guns (Silverton Pretoria) I realised that the heavier, sharp point pellets seem to generally work best. The rifle is a Gamo Hunter 440. Does anybody else wanna share experiences? Arlaz Hawks and Gamo Magnums seemed to be most accurate at around 900fps? Doe you guys find pellet shape to make a difference?
