HI , Gents I have just swoped at a shop my 177cal wolverine for a secondhand FX Royale smooth twist in 177 cal with 480cc carbon fiber buddy bottle on ,up to now my divers bottle only has 180 bar in so that all i can put in the royale, but tomorrow i am going to get my divers bottle filled , any information will be gratefull the gun is in a black tactical stock with a hogger milbro silencer, at the moment i am using bisley magnums and it gets tight groups with them, and it might seem a daft question but will the bottle have a biger sweet spot for accuricey. THANKS bob.
