hi--looking to buy binos foe target shooting--pistol and rifle

how do the numbers work--ie

1:how is minumum and maximum vir=ewing distance determined:

2: what do these numbers mean 8X40, 10 X40, 12X55, 25x125-80

3: what should i be looking for if i am looking for minimum distance: 3 metress and max distance : 1000 yards

thank you
 
If your intention is to make out bullet holes past 100 yards,you would be better served with a spotting scope.By the time you get to 200 yards you would need a very large pair of binoculars that would have to be rested solid,or mounted on a tripod.

As for the numbers 8x40 refers to 8x magnification,and 40mm objective lenses.
 
ok makes sense--so ideally i need a pair of binos for pistol and a spotting scope for rifle at 1000 yds---

in terms of 40mm objective lense---is this the size of the lens and what are pros and cons
 
Typically it will be;

For Binos
00x00mm

First number being your zoom, and the second number being your lens size. Bigger = more light. If you have adjustable binos, see below, same as a scope

For Scopes:
00x00x00mm

Typically for optics the first number is your base level of zoom, the second number is the maximum zoom (adjustable) and if it has a third number such as 40mm, that is the diameter of the lens, and thus the bigger the lens the more light it will let in, the better clearity and visibility you will get especially at distance or in low light.

You don't need binoculars at all,get a good spotting scope,and you will see bullet holes from in close to several hundred yards out.However,I wouldn't count on seeing bullet holes at 1000 yards with any optics.
 
i agree that a spotting scope is the way to go for target shooting----

do spotting scopes come with rangefinders---

is there any way to determine the minimum and maximum distance from the numbers---

i apologise for questions that may be silly---
 
Be aware that if you want to see bullet holes a long ways away,you need quality optics,not just more magnification.A larger blur,isn't any advantage over a smaller,but clearer image.As well mirage can really limit the amount of magnification that you can use.
 
right now i need something that will let me see bullet holes from 3 metres to 25 metres--what would you suggest in terms of magnification and lens size

I'd say any 8 or 10 magnification binocular would work at this range.
Do you have difficulties seeing the holes at 3m?
 
Binoculars at around 7x or 8x magnicication should do for your pistol shooting at up to 25 metres, and are generally useful for other things. At a range of 100m you'd need a level of magnification that is pretty high for a general purpose binocular and then it's worth getting a spotting scope. As others have said, the higher the power of magnification the better quality of optics you need to see what you are trying to see.

If you can't see the bullet holes at 3 meters,you need to see an optometrist.As for 25 meters,I would get a small spotting scope.
 
I can see the holes at 3m...I just want see them more precisely on a target.

I think a small spotting s cope is the way to go---
