I shoot steel often and would prefer it do to the fact that you get an
auditory response when you make a hit   I ran across these types of
targets http://www.hornady.com/store/Hornady-Self-Healing-Target/
and my mind started to spin with possibilities.  First they are lighter
to transport, second they cost less but I still want cheaper.  Anyone
know of any type of sheet material that I can buy and cut my own out?  



Most
of the time I train with IDPA or USPSA type targets since I shoot them
in competition and have hundreds on hand, but I hate walking down range
and pasting targets.  I wanted to train some this weekend and I have
about a doz target stands on my little range but again wasn't excited about pasting targets.  I just punted and bought
some conveyor belt material that is 3 ply with fiber belts between the
layers - no steel belts.  I just bought the stuff that was 7" wide and
about 3 feet of the stuff for a less than $3.50 per foot.  Bottom line I
can cut 4 pieces that are 7" X 9" and suspend them with some twine for about $11.



I
hope the conveyor belt stuff reacts when hit and holds up to many
rounds.  So what do you use for cheap reactive targets?  I saw these and
they look cool, but at $30+ each for fancy empty soda cans - I'll pass.
