The best cheap start to 10 mt is with either a Walther LGR or the newer FWB 601, both go for similar money at around £300, both are cheaper and better than an MPR and are easily capable of shootings 10's all day, with the right shooter of course!
My personal preference is the older LGR which I think is better ballanced, but we have both as club guns and they are both excelent.
Good shooting
