Question How much scope is needed for 100 yards? 150 yards?

Is there a rule of thumb or something to know how much scope is needed for a particular range? I'm new to rifles and scopes but have learned the 3-9x40mm is a very popular scope. But is it enough scope to target shoot at 100 yards? How about 150 yards? How about hunting squirrel at 100 yards? How does one determine what is enough scope for a particular use?

Thanks for the help!

Way more than enough - Some of us use iron sites for that distance -

The distance you can shoot doesn't determine how much magnification you need. The size of the target you are aiming at, at a given distance does.

For example: You could hit a barn door at 100 yards with no magnification. You could not hit a bullet hole at 100 yards with no magnification.

If you are shooting typical NRA bullseye targets, or even something half that size, then all you need to shoot accurately on those targets out to 1000 yards is 10X magnification.

Another major factor is the quality of the glass on the scope. The better the glass the lower the magnification you can get away with.

If you are trying to see bullet holes at 100 yards you need more magnification. If you are trying to shoot great groups at 100 yards you need an appropriate size aiming point and good glass.

I can shoot very nice groups at 100 yds with a 4x scope but until I break out the 20X spotter, i have no idea just how good or bad they are.

For squirels @ 100yds, I'd think a 16x or higher would be the ticket.

100 yards you can do with a Mod 0, Mk I Eyeball.



For precision work (groups) @ 100 yards, anything 2-10x should be fine.

I find a 2.5X is more than enough for all the way out to 300 yards which is as far as I can shoot at the local range. IMO I'd go for a fixed power scope somewhere between 2.5x and 4x.

Of the scopes I shoot, my 16X is my sweet spot. I shoot scopeed rifles from fixed 4X to 8X-32X. The higher power scopes require a very steady hand/body because any little movment will casue the scope to go sideways ... steady includes breathing !!!

3X9X40 will do fine. But if I were using it on a varmit rifles for squirrels mostly then I might go with a 4X12X40 or even more. If it is big game and targets the 3X9X40 or 3.5X10X40 will be a good choice.

Minimum you need 1x for every 100 yards

I shoot irons to about 400 yards. I also have a .22lr rifle that, back in '87, I built for silloutte shooting (40-100 meters). It has a 6.5-24 power scope on it. I'd use it at 24x to shoot 40 meters while standing. So, it really depends on just what you intend to do, your level of expertise and your preference. A 3-9 is a great starting point though.
