when I chamfer a round...

[Nsghunter]

When I chamfer the id of my rounds it leaves a lip around the od. When I chamfer the od it doesn't go away.

1. Am I doing it wrong?
2. Will it hurt the round?
3. If so how do I fix it?

What tool are you using?
How much pressure?

I still use the old RCBS tool with light pressure in and out. Have never had a lip form. (And I've sat and watched a lot of TV prepping brass.)

Chamfer and debur

I felt like the inner portion of the tool deburred.

That's how it works. I've used both shown and the rcbs is superior but also quite a bit more money

Have you tried rotating the chmfr tool the opposite direction? Mine cuts both ways, but the angle of the flutes dictate a uni directional cut direction. It just cuts smoother using the reverse direction. It may actually be just "rolling" the burr down even.

My big concern it's going to make the round dangerous to shoot or chamber? Or will it be ok?

I believe I've tried rotating both directions, the edge is smooth and sharp but there is a lip on the outer portion that will alcatch a fingernail.

I can make this happen by pushing too hard. Use your outside chamfer tool and clean it up.

1. It won't affect accuracy to the point you will be able to detect.
2. It won't affect safety. Too large a lip will result in chambering problems,you'll feel extra effort is required to close the bolt.

Thanks Dave, as always, my first concern is safety the second is accuracy.
