ORA PR is only shot out to 800 or 900 yards (depends on the match director). ORA PR follows the NSCC course of fire, and that goes out to 800 meters.
Haha I'm just trying to get to the point , "precision rifle" is a pretty broad term , if your shooting ORA it's stationary targets at set distance . So now we got a good start !
ORA PR may be at set distances, but it does have movers. Clean the mover and you have a good chance of winning the match if you do well in all of the other areas. All of the guys who shot 50's with high V's on the movers run FFP.
Shooting for score , a second focal plane scope may be a better option . As you zoom in the reticle becomes thicker on a FFP, this will block more of the target and make precise aiming more difficult . The down side is any sub tensions on the reticle will only be true at a certain magnification .
You've got it backwards. Notice that BOTH the reticle AND the target are changing size in the FFP scope when you change magnification? In an FFP scope, the reticle stays the same size
relative to the target. It is always the same size
relative to the target , regardless of the magnification setting. That is the point of FFP. Its in the SFP scope that the reticle changes size
relative to the target when you change magnification. That is why the reticle is only accurate at one magnification. At half magnification, the reticle covers twice the amount of target, and so on...
The reticle that was posted is .15mil thick so at 1000yds. Would be 4.2 " of target coverage at 1000.. If I recall the v-bull is 5" .. So you've essentially covered the whole vbull
0.15 mil is the width of the 0.5 mil hash marks, not the thickness of the fine lines. Not that that even matters since the TMR has a center aperture, making it impossible for the reticle to cover the aiming point on the target. In the 8.5-25x TMR, the center aperture is 0.06 mil (0.2 MOA) and the fine lines are 0.02 mil (0.069 MOA). On most high end FFP scopes, the fine lines are 0.025-0.035 mil (0.086-0.120 MOA) for the popular reticles (Gen XR, G2 DMR, MSR, Klein, P4F...). For comparison, the MOAR reticle on Nightforce's 5.5-22x SFP scope is 0.140 MOA at 22x. It will be twice that at 11x, and four times that at 5.5x.
