I bought a used 8mm-06 Clymer reamer in allegedly good condition. After deciding I no longer need another project, I was going to sell it when I took a closer look at it. Someone cut the shoulder down, probably to cover or repair having abused it. I believe they slightly over cut it, and the only way to salvage it would be to cut down the neck, making it a tight neck 8mm-06. Opinions, please.
