I had some max length magnum primed cases I wanted to use , I decided on 158grn Berrys bullets plated round nose. I used 6grn unique.
Because the case was so long I had to seat deeper than usual to keep the COL down.
I tried to use the built in crimper but I wasn't getting anywheres until I screwed it deeper then I couldn't raise the press arm but halfways.
I tried to use a Lee factory crimp die and with much pressure I got a razor thin light crimp.
Should I be using the Taper crimp for these?
