I used to use a regular "wrist coach" for exactly that purpose. Printed and laminated my own dope cards that would fit in there. Had a different card for each rifle / load. Its ability to stay where you want it depends on the shape of the stock.speaking of "taping ballistics to your stock"... does someone not make a handy ballistics chart holder thingy
like the quarterbacks play book wrap on their wrist?
I get tired of tape going all gunky and letting go, etc.
Most of them use Velcro, which is way too loud for a hunting rifle. I replaced the velcro with magnets.
