I have not owned any scope that was not a Leupold for about 30 years. I have nothing against any other brands - just trust what has always worked and I could afford to stay with Leupold. I have about a dozen. Regarding eye relief, I have two scars that form a perfect "X" over my nose and between my eye brows. One scar was from a left handed shot angling downward with a 30-06. I saw stars. The rifle was nested in my armpit and not on my shoulder. The opposite scar was from a heavy 25-06 that was settled in sands bags and unsupported. She jumped back at the shot.
Eye relief problems in my 40 years of experience, have come from shooter errors, more so than from manufacturer limitations. Ask anyone with a cresent scar over their nose. They will probably tell you the same. A steeply downhill shot is going to get you every time.
