weigh it
then store it in something that works for you
i put my weighed charges in little 1 oz hand cleaner bottles i went to the mall in picked up at claires boutiques of all places
cleaned em out at home real good
bent q tipped the inside of them
let em dry
the mouth of the little bottle fits right inside of the muzzle
and their is no static clinging grains of powder
works for me
i shoot 70 weighed grains from digital scale
picked it up from midsouthshootersupply for 30 dollars
use a taped up paper funnel to pour the charge into the bottle
