OK, here's an update on this sorry CenterPoint Spectrum 4-12×44 FFP scope from Crosman:
CALIBRRATION OF THE RETICLE:
I HAD to make this scope work, I needed it, so I did the leg work measuring the reticle (I'd say accurate to ± 0.1 moa).
I calibrated the reticle in
MOA
— because the turrets are in MOA, and it seems to make no sense if turrets and reticle speak different languages….
However, I've met so many shooters who somehow like this disconnect, so for your enjoyment there is a calibration in
MIL
as well. 😆
I'll attach a JPG and a PDF file of both the subtension in MOA and in MIL.
What's left for me (and any other owner of this scope) is to figure out, what range each of the elevation subtension represents – with a certain pellet–power–range combination.
Should you chance upon the reticle or a similar one in
Strelok Pro
, let us know here in this thread, plz.
Matthias

That is a very different BCD reticle that Vortex's BCD?
Since I am not a turret twister, the mismatch between turret and reticle does not bother me. It is weird however...
Hold over/under for me.
What does bother me is when some fasteners are in Metric and others are SAE, ON THE SAME GUN!
