So nope, not really good enough to load with but not bad given small logs.
When Using H4831 I throw low and trickle up. (I don't shoot that much 7mm Rem Mag so I don't mind trickling)
H4831 is small logs, not known for it's metering qualities. (but it shoots well
)
about 1mmX2mm

Not perfect but I could tolerate a .2gr swing if I was not loading at the MAX
So is the Lee PPM perfect no, but not bad.
