10 meters........ off hand ............ with the Gamo target that fits their trap. These are available most places... relatively inexpensive .... and because most of us are not Olympic candidates ( LOL); do present a nice challenge .5 shots per target ......... 4 targets, 20 shots , for a possible total of 200 points . Shot has to be totally inside the 10 ring to be an X , no line touching . If it touches the line, it's just a 10 . Pellet just has to touch line for greater value. This could be used in all shooting divisions and styles. , springer , co2 , pumper, PCP, etc. kirby
