I'm not sure what target sheet your talking about ?
Mine didn't come with one unless he's added something to the packaging since I got mine.
Here's some pics in the I.O.T.A thread if that helps. http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=2385570&page=3
You can also use your laptop as target with any picture you like on it, makes the image nice and bright indoors as well.
I think someone else posted this up too, but I use a digital target frame. I have it 'cycle' through various targets. I practice various drills to practice getting into position from standing etc. Love it!
