Perfect Powder Measure

Post by chacam »

I am using the perfect powder measure with titegroup and I think I have a leak somewhere. After a lepoaring sessions, I am seeing several grains of powder on the bench. Not sure if it is coming from where I hold the shell into the tube or elsewhere. Can anyone offer any advice? Thanks

Yep that's not an uncommon thing. Most of the time just tightening the screw will solve the leak because it's comes from cone-housing fit. Usually it happen with very fine ball powders. No need to crank it to tight, just a smiggin.

Yep, cone/body fit. I have some WC820, a very fine ball powder and (don't tell any Lee Haters) it leaks like a sieve... ;) I just tighten the assembly screw a bit and sweep up the spilled powder...

Lap the parts then coat with graphite before reassembly.

GasG is right lapping the cone in the frame fixes leaks of even the finest powders. https://www.lee-loader.com/viewtopic.php?f=21&t=1875
