COOL TOOL I just got it I think it was in my mail box for some time I noticed it pushed to the back today. I reamed 5 (338 Yogi) cases today and will try them tomorrow and see what the difference is. The reamer centered the flash hole, I never noticed that they were that far out of center. What will the larger flash hole do to pressure. I would think it would increase because of the difference in ignition.
