Shooting this morning at 500 and 660 yards, that's as far as my range allows me to shoot. Day in and day out I consistently shoot sub-moa at these distances. Today my last shot at 660 yards, I pulled bolt rearward I noticed a plastic tip from one of the 30 cal. 220 gr. ELD-X was laying on top of my magazine, that shot was 4 moa low. I don't know if the tip missing or was it me pulling a shot that resulted in that shot being low. Is anyone else having problems with tips breaking off of Hornady ELD-X resulting in shots being sprayed out of your groups?
