RWS Meisterkugeln are cheaper, and shoot well in my Steyr LP10. I have used RWS R10 and there is no noticeable difference for me between the two.
By comparison the new Eley pellets are expensive at £11+ for a box, but I doubt I would notice much difference, if at all if I used them.
10 shots with RWS Meisterkugeln at 10M shooting one handed during a practice session. Never the same in a comp though
Depends how good your shooting is I guess
