pellets, Pellets, Pellets, - I keep saying the word, but it still comes out 7 to 9 quid per 500

I am shooting with an LP50 and loving it - I am being very careful - until I join a club - but still managed to let 300 or so pellets go down the back garden - considering the bad weather that's not bad

But I am wondering what other pellets are recommended here - I am using Finale Match - but they are not cheap, they were given to me with the pistol and they seem to be not the "inconsistent week link" I am afraid that me - so I am thinking a less expensive pellet to start with - or is that poor practice and am I better sticking with one make of pellet from the get go.

Over to your wisdom......
