You'll notice the Dasher brass I ran in the video a while back was sitting at about 38lbs average peak force. Which is right where I've run that brass for the last 8 firings. Consistent 1/4 to 1/3moa for the past 1800 rounds of barrel.
I've known most guys, even ones that think they know what they are doing... run heavy loads on the bullet during seating. They fail to understand they are deforming the ogive/jacket, and scarring the bearing surface.
I mean, why do people think I went to rice tumbling in the first place? Rice feeds the necks accuracy juice.
Seriously though, I still haven't found a better way to process the ID of a fired case to give the best relationship between the neck and the bullet. I've felt it during seating when it was wrong before... and now the AMP shows when its wrong much better than I could ever feel.
Nothing is guaranteed, but if something seats way easier or way harder, you can bet it will come out on target. That's the whole point behind all of this, and its all old hat. Like, that part of this has been known forever. I'm seeing as little as 8-10lbs of force variation showing up on target. I just don't have enough rounds tracked and fired to be certain of what the "threshold" of a culled round should be yet. It's definitely not 5lbs... at least not in my process.
Yup, which is why the biggest benefit for me is being able to relax and watch the graph, rather than have my human sensor pack switched on into high gear trying to feel every little thing. It's surreal to be able to just be relatively mindless during the bullet seating op. lol I mean, I dump out of the prometheus, shove it all in the die, click go, and glance at the pretty colors... into the ammo box it goes. It's crazy.
