My resized brass is about .005" longer, so in that case 2.225" it's touching and I load them at 2.215" giving a .010" jump. At 2.260" they would be about .040" into the lands, you don't want to go there.
But like grayfox said, it's best to check with a comparator and gauge.
Does the length of the brass make a difference here? Since the bullet seats inside the brass, and not on top of it, isn't the length of the brass, from a COAL perspective, a non-issue?
If 2.220" is touching the lands with a specific bullet seated in a piece of brass, then any other piece of brass into which that same bullet is seated would still touch at 2.220", even if those pieces of brass vary in length. The bullet would be deeper in some cases, and less deep in others, but if the COAL is the same, the length of the brass doesn't impact distance to lands..........right????
