Re the target, it seems to be holding up pretty good, getting cut up, of course, but how long it will last is going to depend on how well you shoot. If you spread the hits out a lot, the cutting up will be everywhere. If you hit primarily in the kill zone area, most of the cutting up will be there and easy to refill with Great Stuff foam. Since I'm deliberately shooting from within 15 yards (as advised by the hunt organizer), I'm keeping the shots fairly well together. It hasn't got a deep enough hole in it to shoot with foam yet, and I'm just kind of guessing, but I'd say if I repaired it a couple of times a year it'd last a long time.
Obviously, another factor would be the proportion of field point vs. broadhead use you give it. It's going to have a rough go for awhile with me, as i have another pig hunt coming up in Jan. After that, it will likely get almost all field point us and last a really long time between fixes.
