Rifle Scopes NF ATACR sfp

[bodhisafa]

I have a c446 second focal plane scope. I need to know at what magnification do I need to have my scope on to properly use the subtensions?

I believe it’s two specific mag settings just can’t remember

 

[Squibbler]

Full power mag would be true subtensions and half power mag would be double subtensions for a SFP. Or for some scopes, there is a designated mag for reticle subtensions on your mag ring , typically "R" marking on ring. Then that setting is true subtensions and half of that mag is double subtensions.

I don’t see a mark on the 25 power setting but I do see a hash mark(line) on the 12 power setting.

 

[Squibbler]

For a C446 reticle subtensions are true at 25x, from what I could find. You should be able to confirm in the manual. So at half power (12.5x ) your markings on reticle would double.

I have a ATACR and I have to set the magnification ring just slightly off the maximum, hard stop, position to be calibrated.

The info should be in the instruction manual.

25 is where the reticle subtends correctly. There is a dot just past the 12 that shows where the measures are doubled
