Remember you are addressing a UK based audience and the OP says nothing about his being an FAC rated rifle so the JSB Beast will be far too heavy.
My recommendation for UK legal limit is to test between Crosman Accupells (14.3 grain) JSB Exact (15.9 grain) and H & N FTT (14.7 grain). In my view whilst buying a load of test bags may be the perfect answer in an ideal world, the OP should be able to go straight to a shortlist of the most likely pellets which will suit his rifle based on the collective experience on this forum.
For FAC use I have never found anything better than the Bisley Magnum aka Baracuda which at 21 grain is hard hitting and usually accurate in all FAC rifles but I would keep the MV below 900 ft sec for best results. I have tried others which work well but are all stupidly expensive by which I mean an air rifle pellet costs more than an entire .22LR round from an established manufacturer. This to me is crazy but others are free to differ as always.
