Generally 2 out of a 100. As for how far I am flaring, I can’t give a number. I slightly increase the flare until I can seat a bullet on the case. Just enough so it barely sits in the case before I seat.

And I load pretty lightly. Generally middle of the recipe for standard .38. I did just switch to Xtreme plated bullets so I load at the high end of lead data. HP38 and a 158 grain SWC calls for a top charge of 3.7 grains. I load 3.8 now. But I had the same amount split with a lead SWC bullet at 3.3 grains of HP38.
