This all has brought a question to mind. I have accumulated many powder measures over the last 50 some year some are short and wide some are long and narrow;has any one checked out which actually works the best?

RCBS beam scale and screwtop clear vials to store,is what I use. I still have a clear volume measuring device to find the intial charge, then weigh and duplicate for vials. Garage sale dot stickers works well to place on the cap to let you know the load at a glance. Works well for me.

I personally never liked the brass volume measurer's, due not being able to see how the pack is with the pour from the keg or flask. I prefer larger vs long and lean.

DONT TAP.if you do it increases the amount. no problem anyhow no matter which way ,just do it same every time.my measure is 36 years old from thompson and still made today. it has no top on it to level the amount.like cayagug said, i use my knife to level it on top.hunting, i pre measure out 2 loads in flim canisters so i dont have to play with it in cold etc.only thing i dont like about the thompson measure is i spill some powder as top is to wide to pour down barrel. i like the ones with spout on but to cheap to buy it, ha.i use funnel at shooting range to pour powder in barrel as in hurry, i spill it.it works good with funnel.
