the homemade bullet sizing die is working
the sierra bullet seems to be very hard when sizing it down by the fact its only 0,08mm : 10,41mm to 10,34mm

before and after

the brass eject excellent in the rifle but I have a problem with the 41 mag shellholder.the brass lose the grip because the rim is turning down from 12,28mm to 11,68mm .
so I cut the groove most modern revolver brass have a little bit deeper till it fits the RCBS No.3 shellholder(8x57)
