What you are requesting are Cole-Parmer Testing Sieves, 8 inch, Brass Frame/Brass Wire
https://www.coleparmer.com/p/cole-pa...ass-wire/2884#
You have to determine the Hold powder mesh size you want: 10 to 270 mesh - they are expensive
If your purpose is to remove the graphite fines from a can of powder: buy a knee high cotton athletic sock - pour the powder in the sock - roll the opening closed - rock the sock back & forth 15 to 20 times. The fines stick to the inside of the sock - pour the powder out and back into the can
This is called Socking BP

thanks for the info John Boy
go on ebay and buy stainless steel screen mesh in small sheets - make a frame outta 2x1 pine
I got brass screen from China and made a frame like Joe. It is a waste of time on Swiss.
I sure agree with that.
It may be a waste of time on the lesser powders too. I don't know even though I own a Cal-Graph screen and tumbler set.
It ends up that cruddy powder is still cruddy powder after the fines are removed. I have not been able to prove to myself that screening poor performing powder improves it.
Maybe I should take the removed fines from the lesser powder and add it to Swiss to see if it then shoots poorly.....Nah!
Chill Wills
i just dumped about 1/2 inch of the bottom of a can of swiss 1 1/2 , no.4 powder , a lot different in the compression effort , the weight per load was the same ,, didnt trust it, now what
