Do you or anyone you have shot with have success shooting with a adjustable objective scope. Sadly I have spent too much money on airgun scopes and not been satisfied with the optic clarity. I have used the Leupold 6.5-20 EFR in small bore and have liked it. So I ordered one and sent it in to get the reticle changed to something with hash marks. I sure hope I am not wasting more time and money. Thanks, Sparky

Thanks, SparkyYears ago I used a 4-16x40 Bushnell Elite4200 scope with a duplex reticle for my hunter class field target shooting and in 2010 I actually took 4th place at a time when the hunter class was combined PCP and piston. Of 17 hunter class entries that year there were 17 entries and all but 5 were shooting PCPs........ Anywhoo.......I migrated from the AO scope with duplex reticle, to an AO scope with a "dotted reticle", then to a couple side focus scopes with "dotted reticle", and currently I'm using a Hawke Panorama 5-15x50mm with AO and "10x half mil dot illuminated reticle" and for hunter class shooting with magnification limitations it does work OK for my skill level.I do believe that the SF scopes with large side wheel are more precise and convenient than an AO, but the recent rule change allowing 16x max magnification in the hunter class (vs the old 12x max) plus my 50mm objective does help with scope range finding, however as mentioned, an AO scope can certainly be used assuming that there is a definite "quick in focus/out focus" when turning the AO. LOL.....a few decades ago almost all scopes used for field target had AOs, but back then the target placement and killzone sizes were definitely more "shooter friendly"!

I'll be 71 years old in a week and for the last few years my greatest challenge is scope rangefinding since my eyes aren't what they used to be. At times it's kinda "iffy" finding the sharp focus (especially at the old 12x max scope limit) but it's still a lot of fun simply getting out with other shooters at a ft course and spitting pellets at holes in metal silhouettes!
AO scopes are fine, and I know a few who use them successfully.However...Aside from the obvious need for a donut and the natural limitations of installing one of any useful size, I have experienced operational complications...Most AOs I have used are rather stiff in rotation... lots of drag in the mechanism. As a result, the image you see while range-finding shifts about the scope's axis. This visual distraction makes it difficult to detect focus lock-in with the additional movement (ie, not a steady view). I have not had the patience of operating a stiff AO for hundreds if not thousands of shots to see if the stiffness loosens up, when there are so many better options available. In contrast, a side-focus mechanism operates with side forces (lack of a better word) that do not torque the scope in rotation. This means that the image is steady, and the shooter can keep a good -- steady -- field of view while focus range-finding.
A donut is simply a ring slid over the objective of larger diameter. It provides a place to mark ranges and, by virtue of its larger diameter and circumference, more space to put the numbers and more space between them.I have seen a couple. I do not know how one fabricates such a donut or how it is secured to the objective ring. Leo Duran has one on a Bushnell Elite, I believe. Might look him up on here or the other color forum and ask.

The scope has a duplex reticle so it will be a challenge like NCED suggested. I am curious though about attaching a "donut" to the AO for help in range finding. Anyone have some help in a DIY or commercial available product?
