| Why do some people shoot with their scopes/optics "backwards?" Better accuracy? |
|
Quoted:
I mount my scope on backwards when I'm shooting individual ants in a pile. I choose my target, usually the one that bit me, adjust my hold over and pick him off. This reduces collateral damage to the rest of the colony. nailed it. ant shooting. i do the same. |

That scope is not backwards. Low power scopes do not need large objective lenses (the front end), like high powered ones do. A typical 1-4x, for example, only needs 20 to 24mm objective lens to produce a decent sized exit pupil (Google that) coming out of the back end of the scope That is less than a one inch objective lens. So, the lens will fit inside a one inch tube (25.4mm) and certainly a 30 mm tube, without any buldge or bell shape at the front.
When you get up to higher power, then the front end needs larger diameter glass to produce a decent exit pupil size at higher power. For example, a 3-9x scope typically has a 40mm objective lens. There are technical reasons for this which are beyond the scope (pardon the pun) of this response. The back end of the scope, the ocular lens or eyepiece is going to be designed pretty much the same regardless of the power range and will be the size you see in that photo regardless of the size of the front lens, the objective. |
