If you start filing the rims on those cases, do you not run the risk of compromising the case and blowing a hole? That's folded steel or brass, and if the former, you will also encourage corrosion.
It's a no brainer to hone the rim recess. It just isn't worth the trouble or risk of rupturing a case. But they are your eyeballs (hopefully safely behind glasses).
I am not sure how removing .002” from the O.D. of the shell rim would compromise the integrity of the hull to cause it to rupture. Just curious as to your thought process, because if I am missing something, I sure would like to know.
