A basic duplex crosshair is hard to match when hunting with a. The reticle or aim point is the part of a scope that has been modified, redesigned, and altered more than any other scope part over the years. Even with low magnification, a shooter can plainly see the target and crosshairs.Ĭheck this article for the differences between FFP and SFP Reticle That is why most hunters prefer traditional SFP scopes. The disadvantage of the FFP reticle is that the crosshairs might be too tiny at low magnification, almost unnoticeable. This is a significant advantage in precision rimfire events, where targets might range from 20 – 100 yards or more, and the shooter may need to adjust the magnification or holdover throughout the shot. Simply put, if all the hash marks on the vertical line (primary crosshair line) equals 1 MOA at a low magnification, it will still be equal to 1 MOA at the greatest magnification on an FFP reticle, but SFP reticles do not. The reticle with SFP optics will remain the same size regardless of magnification change.īecause holdover values do not vary with scope magnification, most hunters and long-range shooters have switched to FFP scopes. When you increase the magnification level on an FFP scope, you will notice that the reticle will expand. A Second Focal Plane is when it goes in close to the ocular lens. First Focal Plane is when the reticle moves in toward the objective lens. When a rifle scope is constructed, the reticle of the scope can be put in one of two positions inside the scope tube. If you have enough of time, the AO controls work perfectly. When moving between close and far targets inside the same shot string, a side adjustment is easier to use. It is referred to as AO or Adjustable Objective. Most tactical and long-range centerfire scopes feature a parallax adjustment knob on the side of the scope, which is commonly referred to as “side focus,” although target shooting scopes sometimes have the parallax control incorporated on the objective bell. Most fixed-parallax centerfire scopes are factory-set around 150 – 175 yards-which is far too distant for most rimfire rifles.Ī Fixed parallax scope is often set at around 50 – 60 yards, which is adequate for small game hunting but results in hazy images at 20 or 25 yards. There are scopes that can be manually compensated for parallax, but others are built with their parallax fixed at a set range. At extremely near and long target distances, the disparity between the planes becomes magnified, reducing accuracy or obscuring the reticle. This occurs when the target and reticle are not on the same plane in the scope’s tube. You’ve undoubtedly observed parallax if you have ever seen a reticle drift about or move out of focus when on a target. Things To Consider Before Buying A Rimfire Scope Adjustable Parallax
