I used this same scope on my 300Wby launching 180's at 3085 FPS & it worked great. Should be absolute minimal difference between that & my 300WSM launching 180's at just over 3100 FPS.
Yes I used the correct magnification, (big triangle) & correct A/O setting. I even double checked.
Ill call Leupold & talk to someone there, & report back here with my findings.
I was not talking about AO settings they will only change the range focus to set parallax correction .
I was talking about the OCULAR eye focus at the back of the scope. If you have long sightedness (Presbyopia) and this ocular adjustment is way back then the power setting marks will be wrong .
Maybe the error was right for the 300 WBY but not the 300 WSM.
I think you have to forget about other guns and cartridges and play with different magnification settings to make it work with the 300 WSM .
Another thing is , you are not shooting with see through lens caps or eye glasses are you as adding another lens of anykind can distort the image .
