Having to constantly refocus is just a part of hunting at airgun ranges.
What Chris said....
Sorry, IAfaug, that this comes a bit as a surprise....
Here are a few things that might help: The most need for focusing the scope, or adjusting the parallax is when:
▪ range is close
▪ the scope magnification is large (24x rather than 9x)
▪ the scope objective lens is large (56mm rather than 35mm)
➔ So, you could try to buy a scope that will help with this somewhat. For example, a
very clear scope (=expensive) will allow you to use
less magnification (an eye operation might, too, at least for me...) — and therefore less need for parallax adjustments.
Or, a 3-12x30 will need less parallax adjustment than a 3-12x44 scope.
As mentioned by others, learning and practicing consistent cheek weld will reduce parallax errors to an extend. But a fuzzy scope image does not get clearer with a better cheek weld.... (I know, bummer.)
If you tell us a bit more about your shooting scenarios, we'll be able to help you more specifically:
▪Minimum and maximum ranges
▪Targets, hunting, or both
▪Power and caliber of your gun
▪FFP or SFP?
▪Do you dial turrets, or holdover?
I haven't been able to try field target, but there is at least one FT discipline where the shooters cannot change anything on the scope after the competition starts. Ask on the FT forum about this particular discipline — and then ask for scope recommendations that give a fairly sharp scope image without parallax adjustments.
I do remember one scope that was particularly developed for this type of FT:
The
Optisan CP 3-12x32P FoV 36-9ft (@100y) | SFP | springer tough | capped 10mil turrets | gridded reticles in mil, calibrated at 10x | 17.2oz | 9.5" short
$330 to 360
