I have always tried to find a target that would hold up for more then a couple months of shooting broadheads and fieldpoints. I usually shoot about 75 arrows every other day. I decided to try the Rinhart 18n1 target. I have been using it now for 3 years and it is still holding together without a single pass through (mostly shooting muzzy practice blade broadheads). The only thing I do not like is the price ~ $135.00. However, if you break it down in terms of cost per arrow then I would imagine it is one of the cheaper targets out there.
Arrow removal is extremely easy with both bradheads and fieldpoints.
With the multiple targets on the 18n1 Rinehart,I believe it will hold together better then an animal target where all the impacts are centralized in a specific region. Compared to the other "block" type targets out there, the Rinehart 18 n 1 would get my vote. I would be curious to see how the animal targets stack up to other manufacturers.
Below is the main webiste for the Rinehart targets:
