Jeep,
I also just realized I made an assumption that you may not have been aware of… Many of the more demanding Varmint shooters favor scopes with side mounted AO adjustments. This is of course as opposed to the older style where the adjustment ring was on the objective bell. This is why they favor the left hand port as it already leaves their hand right next to the AO ring.
(In fact most of the top of line custom varmint rigs are now featuring right hand bolt--right hand loading [/i]even for left hand shooters for many of these same reasons..but that is another topic as this thread was meant to discuss factory guns…)
Side Focus A quick way to beat parallax
My favorite varmint rifles have the bolt handle and loading port on the left side, even though I shoot from the right shoulder. This way I can load and operate the bolt at the same time my right hand is moving the rifle to the next target.
The beauty of the parallax focusing knob, like the one on this Zeiss scope, is that with my left hand already close to the port side focusing knob, it takes only a moment to bring the target into sharp focus, even as I’m applying pressure to the trigger. You literally never have to take your face off the stock. It’s incredible how quickly you can acquire targets and get them into crisp focus this way, which means you’re able to burn a whole lot more powder in a day than ever before.
