Standard reticle? Zeroing has nothing to do with a reticle, are you referring to MILS vs MOA and understanding the difference?It was a .338 Lapua Magnum caliber. He had never shot it over 100 yards before the elk hunt.
The times I took him to the range prior to the hunt using the mil-rad scope was pretty much a disaster watching him try to adjust the zero like a standard reticle.
He refused advice as I do have experience with his system.
Scope not correctly zero’d for long range, shooting downhill at 45 degrees approximately was his issue. Not understanding the ballistics of a bullet in flight with those parameters at hand was his issue. Every shot was likely over the top of the elk.
