    Follow-up to the original issue. The Lee 120-TC, seated with the tiniest bit of shoulder above the case mouth, works pretty well.

    Sized .358" and powder coated. 4.9 gr Unique makes it run well. Depending on the brass, that means a bit of powder compression.

    No not there. Seat to middle of front driving band. Do a plunk test, if it doesn't pass, seat to just a smidge below the leading edge of the front driving band. If it doesn't pass the plunk test ? I don't know what to tell ya.

    4.8 gr unique and 105 swc is very accurate in my p38 I just tested today. I did have some failure to feed issues though. Can you look at my seating depth and provide suggestions . Thanks , I’m at 1.070” just in front of the second band. Should I be more forward,?

    The boolit needs to be deeper into the case ( For my P38 anyways) The top edge of the case mouth should be just below the very top edge of driving the band and above the crimp groove . Right now you are seated below the crimp groove
    Move the case mouth/edge up to the next band , effectively seating the boolit deeper into the case . There is plenty of room ...it's a short boolit .
    4.7 grains of Unique was the lowest charge that gave reliable functioning and shot to a 6clock hold .
    I would do a photo if I could but lack skills .

    My OAL dimensions may have been off , it's hard for me to read dial caliper lately, blind in one eye , can't see out the other !
    seat the boolit deeper OAL be hanged .

    4.8 grains Unique should be right on

    As per photo in post #26 ... That looks just right , do it pass the plunk test ?
    ( it should ) If so , range time !
    This should cure any failures to feed .

    I don't load for a P38 but several 9 mm and find seating a round nose or truncated bullet with about 1/16 to 1/32 " of the frant driving band to work well.
