This one is cool. If you reload, get a chronograph. With this program you can see how loads are "really" performing. Factory ballistics differ from handloads.
The first chrony I had, WAS the shoot over type. Well, one day at the range I didn't shoot over it and put a 168gr .308 round through it..... I would shy away from the "shoot over" type of chronograph.
