I knew I should have kept my mouth shut......

Went into my local to drop off some flyers for our Air Rifle and Pistol club. Got chatting to the owner, and asked him if he had ever had any Webley MKVI revolvers in pellet flavour in stock........Well you can guess the rest, 10 minutes later I'm back in the car with my new purchase

Anyhow, it seems good, and after about 40 shots the trigger is smoothing out really well. But- what is the best pellet to use? I've tried eley wasps (rubbish) JSB's (too heavy) Accupells (possible...) and Bisley practice, best so far but not perfect.

So a question for other owners- what have you found to be the best?
