The home made target worked awesome!
Shooting 45# Sage, Easton xx75 2114 Superlites with 100grn field points, the arrow only penetrated about 4 inches into the foam @ 10 yds. They are a little tough to pull out, but after breaking it in a bit more, I'm sure they'll start sliding out nicely.
$11 all said and done... not bad. Now I just have to start finding some of this stuff for free and I'll be set.
