35,
Those are some great animals and obviously represent good kill shots. But, respectfully, they don't really show whether or not your scope held zero. Without having a mark that shows your point of aim and measuring from there to the point of impact, all we really can tell is you most likely hit within 8 inches or so of where you were aiming. Again, I'm not trying to trash what look like great memorable hunts, nor am I claiming you didn't hit where you aimed, I'm just trying to explain what data can and can't be analyzed from seeing pictures of dead critters vs a test on paper with exact points of aim and impact.
So if you are trying to show that even though a certain scope might not perfectly hold zero, it can still be used somewhat effectively (or in your case very effectively) to kill animals, then I think you've shown it well. However if you are trying to show that a certain scope reliably holds zero, then I don't think showing successful kills really gives quantifiable evidence of that.
And I guess this reply isn't specifically aimed at you, you just posted a good example. Many times I've seen replies in scope threads of "I know my XYZ doesn't have any problems because I've killed so many critters with it."
I'm glad your VX2s and VX3s are serving you well, and if I ever ended up in the right place at the right time I'd join you and your Leupolds on a hunt in a heartbeat.
