full length sizing die and factory new cartridge cases

[pocketshaver]

ive only used PPU for the mauser.. so far ive only had to reload factory ammo that I shot.

emailed the idiots at LEE and they state ALL factory new brass comes sized .002 UNDER bullet diameter, and the mandrel is sized .001 under bullet diameter... so that the mandrel "cant fit into factory new brass".

but I have always seen on forums "simply run the factory new brass through the full length sizer to get the mouths correct"

I ran into a similar issue and applied two solutions so I don't know which did the trick. Neck size first with die touching shellholder and back one full turn and a touch of Imperial on the expander ball of your full size die every 5-6 rounds. Never thought of the awl trick ( ), I used an undersized pilot from a trimmer clamped on a small vise and sorta press the case mouth round. The awl seems alot easier.
