Just picked this up, 45 cal disc rifle (that is whats stamped on the barrel) blued fluted barrel, fully adjustable fiber optic sights with synth stock. Appears to be in very good condition. So can anyone tell me what I got for sure? I would like a manual does anyone know of any online sources? Thanks for the help by the way this will be my son or daughters gun after I get it shooting if it will shoot. Any tips or advice on bullets and powder charges for deer ? Thanks all and GOOD HUNTIN!!
