Dennis got it right.
I check my flare with my bullet .. Here is a picture.
But first I will explain the picture.
From the LEFT I have NO flare and the gas check on the base of the bullet will not enter the case.
Second from LEFT is how i like to make my flare.. the gas check enters the case about 1/2 of it's thickness NOT much.. I flare the same for my non checked bullets in lead also.
3rd from Left is a little too much for me.. is acceptable for some though , really not working the case mouth too much. but not needed either.
Last one all the way to the Right you can now see the flare.. way too much and hard to iron out and will lead to a split neck much sooner than the other cases.
Some dies will have a stepped flare.. where the case gets enlarged down deeper and the flare is at the upper portion of the case mouth.
Like Dennis stated almost invisible.. even in the picture it is hard to see the flare except for the far right case.
