I'm just a bit confused now whether the recticle's lines are going to change with magnification based on whether it's a first focal plane or second focal plane scope.
Reticle remains in same position relative to lenses, image grows larger or smaller relative to reticle depending on power setting.
My particular load in my .30-06 works well at 8x in the summer, and equivalent yardages are at 7x in winter. This is due to velocity loss because of the colder temps. I've shot mine out to 600 yards with a 200 yard zero and the BDC and Spot On did a good job.
