Any bullet setback greater than 0.060" is going to raise pressures. In already max pressure ammo, like 40 & 357sig, it will be dangerous levels. When it gets to the point you have there, pressures may actaully decrease a bit as there is not longer any neck tension. Either are unsafe to shoot. In some calibers, setback is going to ahppen after rechambering a round 3-4 times & has to be watched. When your roudns are 1/16" shorter than factory, time to put them in the nogo box & break them down for reloading or disposal. The 357sig is one fo the worst offenders, so watch the ammo closely. It should NOT IMO, happen after one chambering. They are not doing something right if that is happening to new factory ammo.
