digital scales
i have a frankford arsenal scale, bought it 2 yrs ago, been working for me ever since, makes me some super accurate loads in any rifle i have, really worth the investment, think at the time i paid 35$ for it?? maybe less i cant remember exactly, make sure room you are in isnt terribly cool, i find it makes a difference to have temp atleast around 15 degrees, i tried scale measure cold, and then at , "room temp" made some differences in measure, also let your scale warm up for atleast 5 mins before use, mine has an auto off for battery saver, just keep starting it up, then try it after 5 mins
hope this helps, i was looking at the cabelas scales they have out, they look very good, may invest in one, never hurts to have a second for backup
