Target can appear bigger?

[oldsparky]

Have you ever noticed a target can appear bigger at the same magnification on different scopes? Why. I have two scopes same make, shooting on the same power and never thought they were any difference. until today shooting them at the same target, same light, same distance

oh more info. one is a 4-16 the other is a 6-24 both sightron big sky models. Both were used a 6x minuets apart same glasses. The target in the 6-24 seemed noticeably bigger.

Are the scopes exactly the same or different power ratios? Variable powered optics are generally variable magnification. The closer the focus the less the magnification. This is referred to as focus breathing. This occurs more with optics with higher ratios, in other words a 4-16x (ratio of 4) would have more focus breathing than a 3-9x (ratio of 3.)

Could be the field of view messing with your perception. What I mean is, a scope with a narrower field of view will have the target swallow up more of the sight picture, making the target appear larger. 


Or it could be one of the scope’s claimed magnification being wrong.

I only shoot two mags thru each gun because it was windy. I dont usually have both outside at the same time. I will have to look at this some more.

 Some mirrors do the same thing.

It common for the intermediate magnification markings to be off by a significant amount. When you set the 6-24 to the 6x mark, it might actually be closer to 7x or 8x. It’s also possible that the 6x mark on the 4-16x scope is really closer to 5x. If having exact magnification and AO range markings are important to you, then you should calibrate by remarking them with your own numbers. Factory marking can be close but rarely as good as we can measure ourselves.
