Once again, I do not want to be trying to hit a ¼” wide piece of steel at 25 yards (rimfire) with a scope not able to fully focus and well outside of its design parallax correction range. The only fixed parallax scopes I have are low-end, low power hunting scopes or pistol scopes. Irrelevant to anyone (virtually all competitive rifle shooters?) who use scopes with adjustable parallax correction.
#Vortex strike eagle how to
The article referenced shows how to calculate maximum parallax shift in a fixed parallax scope at distances other than the fixed value. PRS type matches, with targets shot at different distances, often within the same stage, heavily favor FFP scopes, with the target distances in rimfire PRS ranging from as close as 15 yards, requiring parallax adjustment at quite close as well as further distances. Benchrest scopes can therefore be SFP, and have minimum parallax correction at 50 yards, but I’m not familiar with any competition scopes with a fixed parallax correction. (What is now often called a parallax adjustment mechanism was historically labeled the distance focusing mechanism.)īenchrest matches are usually shot at fixed & known distances, with a 50 yard minimum for ARA Rimfire BR. When the image (target) distance changes, the plane of focus changes, and the scope is adjusted to bring the two image planes (reticle focus and target focus) coplanar. This is generally also when the image is in focus to the viewer, if the reticle has been focused properly to the individuals’ eyes. Parallax is eliminated when the focal plane of the reticle is coplanar with the focal plane of the image. This occurs without scope or rifle movement, and can cause a shooter to set their point-of-aim for a shot incorrectly to the point-of-impact the scope should actually indicate, and to which the bullet will hit. Parallax is the shift of point-of-aim through a scope with eye movement away from dead center viewing. I don't wish to belabor the point, and someone can correct me if the following is not a (albeit simplified) explanation of parallax adjustment. I have been very happy with both my strike eagles and my viper scopes.ĮTA - Did a little looking and it appears the venom and SE have the same glass. I only have Vipers and strike eagles, except for a pistol red dot venom. The venom has none of those things, but I thought it at least had slightly better glass than the SE.
The strike eagle has illuminated reticle, more room for zero adjustment, more eye relief, locking turrets, i think it is slightly lighter and smaller, but has China glass. The Venom, I assumed was part of the Viper line, and Phillipine glass, but I may be wrong about that.
The Razor HD AMG is made in the US from Japanese glass. The Golden Eagle is also Japan, the Diamondbacks are China. The Strike Eagle lines use glass from China, which is their lowest tier glass, the viper lines use glass from the Phillipines, which is their mid tier, and the razor lines use glass from Japan, their top tier.
