How much flare should there been in the neck of a pistol case .  If the bullets can easily slide it is that too much or should there be some resistance or a lot of resistance.  I am reloading 40 S&W bullets are 180 FMJ.  Lee Dies.

Just enough so the bullet doesn't get shaved on the way into the seating die. Too much flare will wear out your brass sooner, so less is better.

Just enough so that bullet base barely fits inside top of case mouth.

.06 flare in the top 1/32" of case mouth is plenty.

Two things need to be addressed:  shaving the sides of a  lead bullet AND making sure the bullet is loaded STRAIGHT into the case.  Whatever it takes to make  these two  happen at a MINIMUM.  The more you flare the brass the more you work harden it and make it brittle.  There are people into competition who place more value in keeping the bullet straight.

You can only flare them so much anyway as it will not fit up in the seating die properly. I probably flare mine more than most just to make sure I don't have anymore of the coke bottle look than I have to. It seems to help with that if you run your flare die a little deeper, but again you can only run it so much and then you will have it rubbing the inside of your seating die.

I think Dillon recommends 10-20 thousands of an inch over bullet diameter.  I usually shoot for that (no pun intended) with my WW boolits and it seems to work.

That's around how much flare I use also.
