As a cripple , stuck in a wheelchair for past 12 years I quit with the games . Since then I am shooting mainly indoors in a abandoned milk processing factory near my home ,where I have clar range of a max 70 meters . With my Novrisch TAC338 Ltd. I have 100% in a 6.5 x 6.5" standard competition paper target ( 27 of 27 BB's in ) For me is good enough. My top score is 27 shots in 5" . It happened only once, but rest of the results are close . With some of my DMR's at 70 meters have consistent success at A4 paper sheet . I can't expect much more form an AEG platform , and having no "wet dreams" about 100 BB's in one hole
