Thin walls...
Fiscus--You want the bullets into the cases with no bulge at all?? As I understand it, that bulge is what provides neck tension and holds the bullet in place while the burning powder builds itself up to working pressure.
Now, we're not talking here about a bulge that impedes feeding the cases into the chamber--this is just the "normal" bullet bulge.
I shoot leage bullseye with a .357 revolver, so you can imagine that I've reloaded "a few" .357 cases. (I use .357 cases loaded with wadcutter bullets, to a .38 Spl level.) IMX, there is ALWAYS a bullet bulge. Same is true for my much heavier hunting loads in .357 Magnum.
As to Remington cases, IMX too, these are the thinnest-walled. I've stopped using them in .45 ACP because they clearly make for a different neck tension than all the other brands (thus possibly affecting accuracy) and am considering not using them in .357 Magnum for the same reason.
