hi all,never held one of these but like the look of them and am thinking of getting one as a fun gun.firstly do these fire .177 lead balls or are they steel?.do they have rifled barrels and are they up to informal plinking on the 10m range or would I be lucky to get anything on the paper?.i am not looking for pinpoint accuracy I have other pistols that will do that .all advice would be much appreciated,cheers..greasemonkey
