My buddy has one of the early models which is heavier than the current model, 11lbs vs 9lbs, or somewhere in that area.
Very accurate! Longest kill with it was in the 225yd range. Not sure if they still have the video on their site that shows a guy shooting several groups with different slug brands at 200yds. My buddy had a neighbor at one time that owned a Tar Hunt, the DSIII was more accurate than his neighbors Tar Hunt. No idea if they all shoot as well as his DSIII or if he just got lucky, but when he pulls the trigger, your dragging.
My buddies has expensive tastes. Likes Rem. Accutips, Rem Core Lokts, Win Partition Golds. SST's and Lightfields did not shoot as well.
If you drive a lot you might want to look at something else. For stand hunting his is the berries if you don't mind the weight, it is heavy.
