I'm on the way home from SHOT and checked the site to see what others saw so I could compare notes. I can't find a single report!
My vote for one of the coolest gadgets is a Kestrel weather meter
that incorporates a ballistic program (by HORUS), thus providing not only environmental data, but a continuously updated firing solution in MOA or mils to the shooter. I've got pics and data on SHOT SHOW report day 3 (last item) on my blog at coyoteschool.blogspot.com, so I won't regurgitate it here.
For those who went, what's your vote for best new item?
