What is a 45-70 Caliber Good for?
The .45-70 is a powerful, all-around cartridge that can be fairly accurate. It has been used for more than a century for the following purposes:
- Big game hunting: For hunting large game animals such as elk, moose, deer, and bear, there is no better rifle cartridge than the .45-70. It peeks at providing a killing blow that even the largest animals fall in their track.
- Dangerous Game Hunting: Also, .45-70 has been used to hunt dangerous game like lions, tigers, and even elephants. However, for dangerous game hunting, one needs to use the right type of bullet coupled with appropriate shot placement.
- Plinking: The .45-70 is a fun cartridge to shoot for plinking. When shooting any firearm, however, proper ear and eye protection is prudent and encourages continued participation in this great sport.
- Cowboy action shooting: The .45-70 is one of the popular options for competitors with cowboy action shooting. It can bear very powerful and accurate cartridges, and many types of rifles can be used with them.
Best Red Dot for Marlin 45-70
1)Holosun HS507C X2
The Holosun HS507C X2 is truly a high-end reflex sight and the perfect optic for the Marlin 45-70, one of the most powerful and versatile hunting rifles around.
It’s packed with innovative features and crystal-clear optics, making it especially suitable for hard-hitting lever-action rifles like the 45-70.
Most compelling feature within the Holosun HS507C X2 is the multi-reticle system: a 2 MOA dot, a 32 MOA circle, or a combination of both enables the shooter to change from one to another.
Smaller 2 MOA dot is best for accurate shots at much longer ranges, while the 32 MOA circle would serve better for quicker target acquisition at closer ranges. In this way, the HS507C X2 is particularly helpful for hunting when the game is fast-moving and/or large in size, requiring speed and precision.
Features Solar Failsafe and Shake Awake technology round out the most notable features that make this sight highly reliable out in the field. Operating system Solar Failsafe allows the red dot to stay functional when the battery runs out of power, feeding from the ambient light sources.
Housing is made from 7075 T6 aluminum for extreme durability in withstanding heavy recoil and rough outdoor conditions. The Marlin 45-70 is known for its stout recoil due to the size of the caliber, and this HS507C X2 is more than capable of sustaining that type of force without losing zero.
In addition, the optic itself is rated to IP67 standards, meaning it’s both waterproof and dustproof-very important when hunting in any kind of weather, be it rain, snow, or even dusty conditions.

Factors to Consider When Choosing The Best Red Dot for Marlin 45-70
Choosing the most fitting red dot sight for the Marlin 45-70 involves paying heed to the few important variables that define and constitute high performance in the field. These are some things to consider:
1. Durability and Resistance to Recoil
We are expecting a quite significant recoil from the Marlin 45-70, and thus it matters to choose a red dot sight that can absorb this recoil without losing zero. Look for a ruggedly made sight material, such as aircraft-grade aluminum, preferably shockproofed. The Trijicon RMR Type 2 and Sig Sauer Romeo5 were built to take heavy recoil, making them quite ideal for the powerful rifle.
2. Size and Type of Reticle
None of them is as popular for a Marlin 45-70 as the 2 MOA red dot reticle, balancing target acquisition with decently precise aiming. That size works well for hunting large game at shorter ranges and still holds fair accuracy at medium distances. Other red dot sights-for example, the Holosun HS507C X2-offer various reticles to choose from in case your hunting requires some personal touch.
3. Brightness Settings and Adjustability
Having a range of brightness settings certainly allows you to adapt to lighting conditions quickly and easily. Look for red dot sights that have adjustable brightness levels, such as the Leupold DeltaPoint Pro or Burris Optics Hunting Red Dot, which can be adjusted to be fine-tuned for visibility in bright daylight or low-light conditions during dawn and dusk hunts. If you hunt in darker environments, then night vision compatibility can be a valuable feature.
4. Battery Life and Power Features
If you are on longer hunts or longer uses, the dot sight should have long battery life. Options like the Sig Sauer Romeo5 feature up to 50,000 hours of battery life, which ensure that you can use them without always having to get new batteries all the time. Consider an optic featuring power-saving technologies such as motion-activated illumination-such as MOTAC in the Romeo5-that will conserve battery life when idle and automatically turn on when motion is detected.
5. Waterproof and Resistance Against Weather
Hunting will more often than not get you exposed to harsh weather conditions. Go for water, fog, and shockproof red dot sights, such as Trijicon RMR Type 2 or Sig Sauer Romeo5. These ensure the sight will function in rain, snow, or humidity and can take extreme temperature changes without fogging up.
6. Dimension and Weight
A small and lightweight red dot sight ensures better handling and balance, especially important with a rifle like the Marlin 45-70 that is usually used in tight spaces such as dense woods or brush. Sights like Sig Sauer Romeo5 or the Leupold DeltaPoint Pro are both light and compact, adding minimal bulk while maintaining the maneuverability of the rifle.
7. Mounting Compatibility
Ensure that the red dot is compatible with your Marlin 45-70’s mounting system; some use Picatinny and others, Weaver. Most red dots, such as the Burris Optics Hunting Red Dot or Sig Sauer Romeo5, include compatible mounts that ensure a secure and stable fit on your rifle.
FAQs
- Is parallax a concern with red dot sights?
Most modern red dot sights, including popular options like the Sig Sauer Romeo5 and Holosun HS507C X2, are parallax-free. This means that the reticle will stay on target even if your head or eye position shifts slightly, allowing for more flexibility and faster target acquisition
- What makes a red dot sight suitable for the Marlin 45-70?
A red dot sight for the Marlin 45-70 needs to be durable and capable of withstanding the heavy recoil produced by this powerful rifle. It should also offer quick target acquisition, as the 45-70 is commonly used for hunting large game at close to medium ranges. Additionally, the sight should be lightweight to maintain the rifle’s balance and maneuverability, and weather-resistant to handle harsh outdoor conditions.
- Can I use a red dot sight on a Marlin 45-70 for long-range shooting?
While red dot sights are primarily designed for short to medium ranges, they can be effective for longer shots with practice. A 2 MOA reticle provides enough precision for shots out to 100-150 yards, which is within the effective range of the Marlin 45-70. For longer-range shooting, a scope with magnification might be a better option.
