There is a bedding in process from new usually after a couple of tins or so, but a lot of the rifles on youtube have been tuned by a gunsmith like tony wall of sandwell fieldsports or dave hall to name a couple , or they benefit from a home tune or fettle with a drop n kit like vmach etc. check out geordiehunters tv on youtube Darryl Marksman on here has a couple of good vids on his process and i can say have shot one of Darryls fettled rifle and they are smooth as i have had my 97 stage 2 tuned from sandwell and around £140 transforms the rifle. It depend of the ammount you wish to spend etc
