You could use any magnification you wanted- but extremely high powered scopes would be useless- the field of view would be so small, you could not find your target. The largest I use on a varmint rifle is 24X- and I would not use that on a hunting rifle. Military sniper rifles generally use less powerful scopes than that.
Magnification, Distance, Objective size, etc..
Yes- called a variable power scope. Perhaps the most common is the 3-9 power variable. Twisting a ring at the rear of the scope changes the magnification.
6-24 magnification, 50 mm lens
The magnification of the scope can be varied between 3 and 9 times.
32mm objective, 4 power magnification.
It is a NERF sniper rifle, but the scope doesn;t have magnification
3 to 9 magnification with a 50mm objective lens
3 to 9 is the magnification available & 40 is the objective diameter in millimeters. The "objective" is the glass lens farthest away from your eye when mounted on the rifle.
It is expressed as how many times larger the scope makes something appear to be. It can be determined mathmatically if the curve of the lenses are known.
It magnifies 4 times, and the objective (front lens) is 40 mm in diameter. A 3x9-40 would be a 3 to 9 power variable magnification scope, with a 40mm objective lens.
The numbers represent the power of magnification and the size of the objective (front) lens in milimeters. 6-24 means the scope has a variable pawer adjustable from 6 to 24 times magnification. The size of the lens determines how much light the scope gathers and the field of view.
One of the most popular brand options in the market is Vortex Optics, due to its exceptional magnification range, high-quality glass, and advanced features for its long-range rifle scope. But if you want to get an affordable and decent scope, you can check out the brand Kalkal rifle scope. It has all the features that meet your demands in shooting and hunting.
