All personal choice. I use a countersink exclusively, that's all I use.@Nick A - I tried a reamer but the first time I seated a primer it felt like there was no resistance at all. I then tried a countersink and created a nice bevel on the rim of the pocket and the primers seated with a little more resistance. Should I stay with the countersink for only 1500 cases?
I'm glad you posted this link. I think I'm gonna give this a try. For the price I think it's worth a try. I got I set of countersinks and a Wilson deburring tool.Both work but I want something more consistant.
