So now I’m confused…

I apparently I didn't zero my calipers before I measured the loaded RST factory ammo the other day. The 2 7/8” RST unfired ammo measures 2.405”. I also re measured my chambers and they still are both reading the same as yesterday at 2.775”. So i would say I'm good to go with 2 7/8" factory RST ammo if I want to shoot it up. Well that's good becuase when I loaded up my proven load the other day and used a plastic shot cup instead of a 1/2" nitro card I had just enough hull length left over after shortening them to get a roll crimp. Now I won't have to cut down the current RST hulls that I know they are short enough to clear the forcing cones without any trimming or I'll have to trim off .025" of hull material I'm guessing.
