When trimming my brass, an I the only one that chamfers outside a bit, then inside, then outside, until I am happy? When I started trimming, I figured it was a good way to not mess up the mouth by going back and forth. As I was trimming tonight, I came across a piece that had a chip missing in the mouth, and it ended up being beyond what I was trimming off. Most times, I toss it in the scrap bucket and move on. This time, I took my chamfer tool and outside trimmed a bit and then inside trimmed and watched for the chip to disappear. What I noticed was I was making a flare. I got sidetracked from my fist test and played with this flare some more. Still don't think I like the idea of trimming a bit more to save a case, but now I think my alternating as I chamfer is a good idea.
