[QUOTE="IHFarmer07, post: 1934916, member: 75397"] Been through this before.......THE best way for me was to buy a K & M neck turner with the PROPER DEGREE CUTTER for the cartridge neck/shoulder degree that you are turning, it is a MUST! Go into the shoulder just a tiny bit and it will take care of your “brass”donut problem. DO THIS EVERY TIME ON YOUR BRASS PREP. [MEDIA=youtube]EyJ9KkE2pVc[/MEDIA] If you decide on neck reaming, which you do you. I tried it and idk, it works but it’s not that easy/efficient. You can go on amazon and get a high speed chucking reamer for cheap, put it in a drill and go.
