Used for 75 rounds . I lent someone my labradar and it took forever to get it back and needed a chrono before a match. Bought and used for load development. Saw the guy at the match and got my radar back. These are not bad actually, I had the magnetospeed V3 before I got the lab radar. I switched to lab radar so I could do my bow and handgun as well. $150 shipped or trade for 200 Berger 140 6.5 bullets.
