I have been reading on some other sights and have been hearing at some local shoots that this year at the Indoor Worlds in Cleveland that there will be a 30 yd and a 50 yd approximate lines. What happened to 30 yd and 45 yd exact max line. Just some one please let me know is it 45 or 50? The approximate is another topic, what ever happened to a laser range finder? There pretty exact!
