Scope height and zero question
Is there any way to help with the high scope mount height on Airforce guns? My zero on my SS is 30 yards with jsb 18’s at 950 fps. When I’m hunting I’m constantly having to refer to my trajectory mil-dot chart on my scope cover. It just seems like I never had this much trajectory work with lower scope height guns. I’ve played with some demos and chair gun and can’t really come up with another zero that would be less work. Any suggestions? Thanks

I put a good quality green laser on my Talon which ended up being mounted on the top side of the barrel between the barrel and the mil dot scope.
I center all points at around 40′ (good for me) and by knowing the relative distances between the mounting points; i.e. the distance between the barrel and the laser and the laser and the scope; I can accurately judge the POI on longer shots (under 100′) by looking at the separation between the laser dot and the scope X-hairs knowing that the POI will be a predictable above the laser point.
The POI (point of impact) will always be at a fixed relationship above the X-hairs as compared to the shown spread between the laser and the X-hairs regardless of the shot distance (not accounting for pellet drop and longer ranges).

Lee, that is the bane of our guns. It is what it is.
What I did to help with this was to sight in at 50 yards, and use the first mil under the center of the cross hair at 20-30 yards. 1/2″ low at 40 with cross hair. Dead on at 50, 2 mil at 80 and just slightly over 3 mil at 100 yards. But it will depend on where your scope mill’s and at what power you shoot. Mine mils at 10X but these settings are at 14x. It will require much less mil’s at 10x. Practice-Practice-Practice, until it becomes second nature at the power setting you prefer.
This is with a .25 JSB at apx 960-990 fps.
