Top 5 Best .45-70 Scopes To Buy 2020 Reviews
1 Vortex Optics Crossfire II Second Focal Plane, 1-inch Tube Riflescopes
In the world of optics, Vortex is a name to be reckoned with. They consistently produce quality scopes at prices to please. This riflescope from the Crossfire II range is one from a good choice of configurations.
This is the 3-9x magnification scope that comes with a BDC reticle and 40mm objective lens.
As with all scopes in the Crossfire II range, quality manufacture is yours. It is made from a one-piece, solid block of aircraft grade aluminum. The scope has been purged, then nitrogen filled and sealed with an O-ring to prevent any fogging issues. You will also find it is waterproof.
With quality multi-coated lens, you are assured of a crisp, clear image when sighting your target.
This is a second focal plane (SFP) Dead-Hold BDC reticle. It has been designed to minimize any guesswork when it comes to bullet hold-over at longer distance shooting.
The reticle comes with three small hash-marks positioned on the cross-hairs. Once the appropriate hashmark is selected, you will benefit from reliable references in terms of bullet drop and range distances. Effective use of this reticle will offer the shooter greater accuracy.
Eye relief is a minimum of 3.8 inches. In our opinion, when using .45-70 ammo, you do not want much less eye relief than 3.5 inches. Indeed, the more, the better. One thing the eye-box does provide is adequate latitude.
Adjustments for windage and elevation is achieved through resettable ‘fingertip’ knobs. You can adjust in 1/4 MOA increments, and each click produces an audible click (although rather quiet!).
- Solid configuration from a respected scope range.
- Effective reticle.
- Vortex VIP warranty certainly worthy of consideration.
- Slight loss of focus at maximum magnification.

We are moving up a notch in magnification strength. This ranges from 4x-12x magnification while the fully coated objective lens comes in at 40mm.
This scope is good for all big game hunters. This Vortex Dead-Hold BDC reticle allows for shooting at a wide range of targets where hold-over may be of concern.

Eye relief comes in at 3.6 inches. If you are a shooter, who wears glasses do consider this against possible recoil issues. If you are concerned, then look for a scope with longer eye relief.

Best .45-70 Scopes Buying Guide
Here are 5 bullet points (sorry!) to consider when looking for the best .45-70 scopes. We will then round off (no more, we promise!) with our conclusion as to which of the above optics we deem most suitable for the majority of shooters.
- Magnification: When shooting at short range, magnification is less of an issue. However, experienced hunters and those wanting to test skills over longer distances will benefit from a scope offering magnification versatility.
- Durability: Consider the environment you regularly shoot in. Any rough conditions mean you need a durable, tough scope. That being said, there is another important reason to choose a highly durable scope with this type of ammunition. The .45-70 round is no pussycat. You will get (and should expect!) some noticeable recoil. Go for a scope that is built to withstand such recoil.
- Clarity: Any scope you choose needs to offer clear imagery. This is where quality optics really count. Look for fully coated lenses, also consider the amount of light the scope offers. This is particularly important for those who enjoy low light hunting. i.e., Dawn and Dusk expeditions. Dependent upon your type of use and preference, you may also wish to consider an illuminated scope.
- Accuracy: It goes without saying that accuracy is of key importance when hitting a target over any distance. For those hunters using .45-70 rounds to hunt larger prey at closer distances, it is absolutely vital! If you are a hunter into this type of activity, then do check the accuracy of your chosen scope, particularly at distances of 100 yards up to 300 yards.
- Eye Relief: The best .45-70 scopes need to offer decent eye relief. The .45-70 round packs quite a kick. Once fired, you will certainly know about the recoil. To our mind, you should be looking for at least 3.5 inches of eye relief, and more is preferable.
