[QUOTE="Pdvdh, post: 1130231, member: 4191"] I'm not going to be offended one way or the other as to your conclusion. MV and pressure will either increase with increased bullet seating depth, or MV and pressure will decrease with increased bullet seating depth. It's a one or the other. So one position / understanding is correct. The other is wrong. And my position on this is the correct one. I've got a quality triplicate chronograph setup. I obtain 3 recorded velocities for each bullet fired. I've recorded MV versus seating depth myself, more than once. My experiences were identical to others that have done this during load development, or just of the 4ell of it. Misunderstanding this concept can lead to rude surprises. You work up a maximum load 0.125" off the lands, and then seat a bullet 0.010" off the lands under the mistaken belief that pressure will decrease, and you could learn the fallacy of your misunderstanding the hard way. So I'll end with this: I tried to steer you to the correct understanding... [/QUOTE]
