Scope Question
I just got a new Condor and mounted a Leapers 3×9 40 AO scope. I sighted the scope in to shoot crosshairs on the bullseye at 25 yards. If I move to 10 yards the point of impact is about 4 to 5 inches low. I can compensate by using the mil dots but that seems like a large POI change for just 15 yards of distance. I can hit the bullseye at 10 yards by raising the scope to the 5th mil dot. Accuracy is dead on…..groups are dime size or smaller. I am using Diablo Exact Jumbo Heavy (18.1 grain) and a power setting of 6. I also shot some Crow Mags and Polymags and they seem to all shoot about the same.
Is this normal for POI to change that much over a 15 yard distance? Should I use a higher power setting? At this level the pellet blows through a 2×4 at 10 yrds.

PW6 is a good start.. PW6 is plenty power and
conservation of air = more shot per fill…I think you could go
with PW2-3 though and get a lot more shots without loosing
very much power.
30yds is a great zero point unless you only have room to do
25yds….Mine is zeroed at 25yds and I aim 1/2 mildot high
at 65yds with PW set on 4/4 using a Talon tank
(smaller air valve = more shots per fill)….
It is a decent trajectory range. I am shooting JSB 15.8’s.
I find them to be the most accurate so far….
When you get a chance, you can move the target in 5yd
increments and see where your trajectory is by,
keeping the crosshairs on the same spot each time
and making note of the Point Of Impact (POI) for each
different yardage…I have wooden stakes set out every
5 yds from 20 to 65yds with dots to aim at so I can
figure holdover…You don’t need a Chrony to figure any
of that… But you can use some of the programs on
that link to approximate your fps once you
know what your holdover is at different yardages…
Good info Jeff. The Condor is my first air rifle and I am new to the sport. I do not have a chrony yet so I cannot check my pellet speeds. I am shooting 18.1 grain domed pellets. Can either of you give me a good idea of where to set the power level and what would be a good distance to zero my scope? I was thinking 30 yds might be good as I plan for most of my shooting to be between 15 and 45 yards. This would put me in the middle of the range and I could use mil dots for adjustment. I have the power set at 6 now and have only been able to shoot out to 25 yards so I have not checked the trajectory past that distance.
Thanks for the reply. I mounted my scope on the tri rail base and used medium rings. My height difference is 3.5 inches. I checked my target and the POI is about 3 inches low. That makes sense now. I also watched the DVD that came with the gun again and the scope mounting section covers this. I just didn’t listen as I was so anxious to go shoot the gun.
Check out this site…It has everything you need to understand all aspects of rifle to scope relations, POI, POA, etc…….
Mike,

Use a ruler to actually measure it. You should be 2 1/2″ to 3″ low at that range. It is due to the scope on our guns being 3″ centerline of scope, over centerline of the bore.
