I'm through buying any other scopes. The Leopolds do the job for me and I have the turret adjustment knobs on all of them. What does sub-second mean?
It takes less than a second to determine the correct range and have your target in the cross-hairs. You don't have to turn any knobs either.
That said, I still love my 30.06/Model 70 Standard weight with the Burris 4-16. I zero at 200yds, never shoot over 300yds with it........
The 400yd shot was an anomoly for me, I knew I could do and successfully took the shot with that Browning .308.
