I'm wondering if anyone else has notice this (not that there's many of us reloading .357 Sig). New Starling brass appears to have the case shoulder closer to the head (therefore farther from the mouth) than my case gauge suggests it should be. This means more neck, and the possibility for more next tension. They still chamber and fire just fine like this. Likely because the case with seat of either the mouth or the shoulder, based on which one hits first in the chamber. When I resize fired brass, I set the shoulder so the case fits the go/no-go case gauge, but between the powder residue coating the inside of the neck (despite tumbling it's never like new), residual case lube, and the reduced neck length, I tend to see prefired cases are more likely to suffer bullet setback. I'm wondering if maybe resizing the shoulder farther towards the case head is a better way to go. However, I realize this may cause the case to wear more quickly at the shoulder. Any thought or experience with this?
