Selling a very good condition Bushnell xrs2 with h59 reticle. Would consider trades for another xrs2 with g3 reticle or something similar. $1100 shipped. I have the original box.
My hornady brass is the same. I believe that it is due to the transition from the body of the case to the case head. The case head is thicker and wouldn't expand as much as the body when fired. I bet you can measure on each side of the line and see the difference.
