Milling 50 bmg brass shell casings for bottle openers , getting a bad finish at end of cut.
Using 9/32 2 flute mill ,holding them in 5c collet holder with thin leather wrapping shell
clamped in the vice at 45deg. Milled in one pass , seems to work ok except the mark left behind when comming out , any suggestions ?.
The mark is on the exit side
Thanks
