lets see i had a bag from sportsmans warehouse that lasted me two years for 30$. then i had a 3d deer for 70. i shot out the core in about 1 or 2 months. and each core costes 20 i think. so i forgot about it. now i use a some type of block target from dicks and i shot it out in about 2 months. im still searching for a target. i heard the rinehart target is great. it 100 bucks though. if you shoot out like all 8 sides they replace it for free i think. im interested in this thread cause i shoot alot and need a durable target too. and i leave my targets out in all conditions except winter.
