A buddy has the same setup and he says that it's 3" but I've also heard others say 4". I'm inclined to go with the 3".

SOURCE: Marlin 1895 45-70CB 26" octagon Barrell

The Leupold VX-II 2-7 X 33 is excellent for the Marlin 1895. Small enough not to unbalance the look of the rifle, plenty of magnification for hunting with the 45-70.

I have one on my 1895 cowboy and I am well satisfied with its performance..

How to Spotting Scopes Work?


Spotting Scope is a type of telescope typically used for observing wild animals and birds. A spotting scope features more magnification than a conventional binocular but less than an astronomical telescope.
The utility of a spotting scope becomes most obvious when the identification of an animal going in a large herd is required. Figuring out a specific animal from other look-alike animals becomes easy with such a device. For digiscoping purposes, few things can beat the power of spotting scopes. It is possible by using binoculars or telescopes to take a closer look at birds or other animals, but if you want a precise view of your target animal, a spotting scope is preferable.
Spotting Scope Features Explained
  • Objective lens
    Objective lens, also known as the Front lens, determines the image quality at higher magnifications. The diameter of this lens ranges from 50-100mm in size. It is also called "Aperture" of the lens. It is wise to buy the highest size of the objective lens considering its weight. Larger lenses allow to pass more light and create more bright images. This means you will get higher image quality with the larger lenses.
  • Lens Coating
    Manufactures often apply the chemical coating, which is known as Lens Coating, on the lens to reduce noise and increase light transmission. They also offer "fully coated," "multi-coated" and "fully multi-coated" lens to improve image quality. The premium quality spotting scopes' lenses are multi-coated with multiple layers on the surface.
  • Focusing
    There are two types of focusing mechanism in the spotting scopes such as Helical and Knob focusers. The focusing characteristics determine how quickly you can focus on the object with maximum precision. Between these two options, the helical focuser is the finest option for birding as it can change magnification rapidly along with the movement of the bird. For hunting or spotting slower animals, Knob focuser is best as it gives you more precise information than the former one.
  • Eye relief
    The eyepiece remains at a little distance from the users' eyes. This distance is called the eye relief where the light rays transmitted from the object pass to enter into your pupil. The comfortable eye relief distance is about 15mm to see the full field view. This feature is very important for those who wear eyeglasses. Nowadays, manufacturers are offering long eye relief for those who need to wear eyeglasses for convenient viewing.
  • Image Quality
    You might have seen some designation on the glass label of the spotting scope such ED glass, APO glass, HD glass, Fluorite glass. These special qualities of glass will cost you more but create a huge difference in image quality comparing low-quality lenses. Remember, you must pay for the good quality images when it comes to buying any types of optical instruments.
  • Magnification
    The magnification of spotting scope is higher than standard binoculars and varies between 15x to 75x. The power of the eyepiece determines the magnification of the scope. The important fact you should know that image quality drops off as the magnification goes up. Even premium quality scopes also lose a little quality at the highest magnification.
The condition of the atmosphere has effects on birding, hunting and digiscoping too. Humidity, ever-moving air, dry climates, dust and so on hinders the magnification and image quality at large.

Twist rate on Remington 700 serial no. F6226557


if its a stock rem model then its got a 1 in 12 twist this is good for calibers of 7mm thru 308


measure the length of your barrel (minus chamber) to find your total twist rate

What size rings do i need for this scope


Choosing scope rings involves the following considerations:
1. Get the right diameter. Most scopes are 1.00" in diameter, but not all of them. Measure your scope tube.

2. Mount the scope as close to the barrel as is practical. The closer the axis of the scope is to the axis of the bore, the less error is introduced by canting the rifle.

3. You must have proper eye relief. If you are shooting a high-power rifle, you need at least a couple inches between your face the the end of the scope to allow for recoil. This is less important for low recoil calibers. You must also be able to position the scope so that you get a full field of view when you mount it to your shoulder to shoot. Some rifles, like Ruger #1's are tricky to get right due to the shape of the action. Some rings are offset to provide additional adjustment room.

I would lke to get a higher spec lens for my konusmotor 500. What is the highest lens I can get for it and where is a good place to buy it?


Highest theoretical power is 250x but it has to be a perfect night. konus does have very good optics but at f/4.3 it is a low power, wide field scope. So 500mm fl / 2mm eyepiece = 250x. Eyepieces of that high power have eye relief issues as well as blurry edges unless you want to pay $500 or more
Here is a good eyepiece which will give you 96x and 20mm eye relief. I own the 12.5mm version

BTW I rarely go over 150x with my big scope, the higher the power also equals seeing more atmosphere

Scope wont shoot good groups


That can get expensive, I had the same problem, bought a Bushnell scope and it went everywhere but on the target, couldn't hold it steady, with my win mod 70 in 308 with heavy barrel, I said that's it, I went and bought a Leupold, no problems since. I don't know what was wrong with the Bushnell, just couldn't handle the blast I guess. I put he Bushnell on my bolt action 223 and haven't had a problem with it, but always expect one because of what happened before. I don't remember the model number, but it was a 3x9. Hope this helps.

Have sighted in a .308 w/150 grain. After


This is a cold barrel warm barrel thing. When cold she shoots dead on. Try to space out you pratice to keep the barrel cool. When the gun warms up things do expand and it can cause the reciver to bind the scope. Also can cause the barrel bore to increse and let gases by pass the bullet causing lower exit speed of the round.

Are you looking set the eye relief or the focus ring?

For eye relief you need to loosen the scope in the rings, mount the rifle to your shoulder with your standard hold and cheek weld. At this point, slide the scope back and forth in the rings until you obtain a full field of view. Tighten one of the rings slightly, dismount and remount the rifle several times to ensure correct adjustment. Level scope and tighten rings a final time.

For focus adjustment (remember that you are using the eyepiece to focus on the cross hair, not your target!) loosen the lock ring and turn the eyepiece until the cross hair is focused. It is best if you check it several times by closing and opening your eye several times. The crosshair should be instantly in focus. If your eye must adjust, then you need to refocus until the focus is instant.

The two dials on the scope are for adjusting the bullet point of impact. They will typically move POI 1/4 inch at 100 yards.
