Interesting reading. Haven't heard much of the one company, but I've been using BIrchwood Casey stuff for quite a while.
My bet is before the dust settles somebody is gonna pony up a lot more technical details on their product than have been in the press before. I've tried home brewing a few of these targets. Paper doesn't seem to be the ideal medium because it doesn't have quite enough give to it and the coating flakes off in transit unless you're very, very careful with it.
We're playing with some plastics but I think it will push the cost per target up to where it's not a real savings.
