good question. depends on the stage, but i have the following tools handy on my person:
a tan 1/2 sheet of cardstock i took to officemax and had laminated
a grease pencil (to write on the laminated cardstock)
my laminated dope card at 50* and 1000 DA with come ups every 20 yards from 100-1200 (tan)
my mil-ranging cheat sheet (in blue)
iphone with shooter ballistic app
kestrel
if the stage briefing includes target distances, i will use my ballistic app and kestrel, to take a current temp/DA and then write my exact dope on the cardstock for all the targets and will run with that. then i just wipe the grease pencil off with my hand for the next stage
if the stage is blind or we have to range it as part of the stage, i run with the cards on a retractable lanyard attached either to my belt or chest depending. i'll usually have a good idea that say, past 700 yards i need to add/subtract a tenth for DA/temp.
most people these days are buying those wrist bands that quarterbacks wear and write their plays on. you can get them from local sporting goods stores. then write your stuff on index cards and slip it in the wrist band. that works pretty well too.
my cards look like this:
pretty difficult to read from the quick iphone pic, but the headings are yards, drop, wind, and lead for movers, and I bolded the even 100 yard lines (100, 200, 300...etc)
The mil cheat sheet has common target sizes across the top (and back, not shown) which go from 1.7" (golf balls
) to full size ipsc, and 48" (common rebar length). down the left side is "size of target in mils" and then the table values are the distance in yards.
however, in my pack, i also carry
2"x3" velcro with adhesive backs
shears (in my med kit)
small pad of paper
business-card-sized lamination kit
(all available at walmart cheap except the med shears)
so if for whatever reason i think it might advantage me to redo my dope card or put some other info on the side of the rifle or scope or wherever, I can write it on the paper, stick it in the lamination and cut a small piece of velcro and stick it to the back, then velcro it to my rifle/scope/whatever
