SFP DOES NOT change the size of the reticle when the magnification range is increased or decreased. This time, it is closer to the ocular lens. SFP or Second Focal Plane, on the other hand, is when the reticles are found at the BACK of the tube. Who benefits most from FFP? FFP is more dependable for shooters engaged in long-range shooting. A closer placement to your objective lens increases magnification and causes the lines to grow larger. It’s placed closer to the objective lens. There are two options where reticles can be placed:įFP or First Focal Plane is when the reticles are located at the FRONT of the tube. #3 Focal PlaneĪside from design, placement is also an important factor to consider. Higher parallax calibration is necessary for farther distances. It will be the best option for any precision match scope. Rimfire scopes can easily function PARALLAX-FREE at mid ranges, provided that the parallax is fixed.įor Rimfire or during small game hunting (around 20-25 yards), we recommend an adjustable parallax that can be set from 50 yards down to 25 yards. However, there are scopes that allow for manual parallax adjustment. There are some with fixed parallax and come in factory settings. The effect of different focal planes becomes magnified, up to a point it’s not useful at all. Accuracy is DECREASED when used at extremes: Really close range or long-distance targets. This instance all has something to do with parallax. When the target and lines do not lie on a similar focal plane within the tube scope, the sight picture becomes obscured, and an adjustment on the parallax is required. This leads us to the second feature: Parallax adjustment - useful when you see the crosshairs floating in and out of focus. The better choice? Centerfire scopes are more suitable since it’s specifically designed for aiming 100 yards or more. Let’s take an example: Complicated reticles can only block the sight picture and the shooter will only see clusters of hash marks when used on low magnification. The finer lines and indicators help in pinning down a target when aiming.īe careful to not choose one with multiple marks as this might COMPROMISE a clear sight picture. It’s marked by 4 heavy lines starting from the edge of the circle and taper down to finer lines and hash marks as they meet in the center. A popular example would be the duplex crosshair. Reticles have undergone a lot of redesigning and upgrade in the last couple of decades. Contrary to Centerfire scopes, there is less risk in Rimfire scopes to get hit by a scope after firing.įeatures to Look for in Rimfire Scopes #1 Reticle Design.Eye relief is basically the minimum distance needed from the rear lens to your eyes in order to get a full picture. Rimfire scopes tend to have SHORTER eye relief.Rimfire ammunition also comes in a lighter casing which also affects the zeroing process.Best for beginners as the recoil force can easily be controlled.Are a bit delicate and MUST NOT be installed on high-recoil rifles.Rimfire scopes are mounted on rifles with low recoil.Now here are some points to remember about Rimfire scopes: The Centerfire scope might not work as well. You do not want to go for Centerfire scopes with the typical 100-yard parallax setting. Rimfire scopes are best for short-range shooting and usually go with scopes with a parallax of about 25 or 50 yards. #2 Can You Mount Centerfire Scope on a Rimfire Rifle?. #1 Can You Mount Rimfire Scope on a Centerfire Rifle?.Difference Between a Rimfire and Centerfire Scope.
