This is my first foray into loading such large cases, and this is a problem that I was not expecting to have. I'm thinking that it shouldn't matter what brand of powder measure is used, as they should all be compatible, right? The problem seems to be with fitting the powder measure to the press. It obviously requires a die which RUM cases will fit into. But for some reason unknown to me, I seem to be coming up dry on that sort of die. Can anybody point me in the right direction, on where to find what I need?
When I first started loading this was the way I went,
At some point I discovered that mounting the/a powder measure on the press caused charge
weight to vary because of the action of the press while loading.
Also the other problem was that I could not see the powder go into the case and sometimes
when removing the case I would disturb the clog and dump powder all over the press and
So I decided to seperate the powder measure and the press to resolve this problem.
What I found was that all powder measures were not created equal. Another case of you
get what you pay for. I tried all of the less expensive powder measures and they worked
fairly well as long as you were consistant with your process. (Tap the knocker on the side
of the measure the same way and number of times every time ETC).
I finally found a straight forward powder measure that was consistant without tricks.
and was happy with it.
Some big cases required a double drop to reach the weight and then I found the best
powder measure I have ever used that solved all of the shortcomings of the others.
It is called a Harrell's It is the Premium model and will drop 120 grains of powder
at a time. It has Clicks for adjustments(200) and each click is close to 1 grain.
It also has a clear drop tube that allows you to see the powder as it goes in the case
that is about 3" long.
It is also mounted in Ball bearings and is the smoothest I have ever used.
He is a great guy to do business with and will make you any size and length of drop tube
I do not own any stock or get a commission I just believe that when a great product comes
along it should be shared with all.
I know this did not answer your Question but I thought I would share my Experiences with
you and maybe save you some time and money, and help to prodeuce better loads.
