Yes, the actual sight height is supposed to be from the center of the rifle's bore to the center of the optic's bore. You can just take a general estimate using a tape measure or you can get fancy and do the math to be very accurate but I doubt it matters unless you are an extremely long range shooter.Thank you Rammac, I put .213 in there and it adjusted my calculated drop only down to 2.1 mils. I had to input a G7 of .6 to get down to the 1.7 mils I was shooting. Your point about my sight height is something I was never really sure of. The mount I'm using is an AERO Precision 1 piece mount and they list the height as 1.5" but I think that is from the base of the mount to the center of the scope tube ... is the actual measurement supposed to be the height from center bore to the center of the scope tube?
I also think I need to go do a turret tracking test ... I'm shooting a Gen 2 Vortex PST 3-15x and I'd like to think it tracks true but i've never actually tested it.
I have two Gen II PST scopes and they are pretty accurate but all scopes should be checked since nobody makes anything perfect every time. I've found that most Vortex products are close enough for most shooters and I've used my Razor model out to 1200 yards and found no tracking problems. The PST scopes are on rifles that I use out to 600 yards and they've worked really well.
