Just a quick blurb. I finally got the gun that had my 6-24x50 Nitro on it out to play with. This is the first time I've really messed with it at over 100yds. Turns out the focus adjustment maxes out at 200ish with the knob tapping infinity. Thought it was probably just mine, then did some research and found that it's not a horribly uncommon problem. I never took my 4-20 past 200yds, so can't say if that one suffered from it. Optically the scopes are still really good, but for my usages not being able to focus properly is a deal breaker, so the scopes on its way back to bushy again.
