One of the most-hyped and debated features of a scope is the size of the objective, or forward, lens. Simply put, larger objectives gather more light, making for a brighter view, especially in low-light conditions.
I dont agree with the popular idea that bigger is better. The larger 44mm objectives don’t in my opinion give that much greater an advantage over a 40mm. At this size the objective allows in enough light for me to scope out even the darker areas of the landscape and certainly more than I can see with my naked eye.
One of the biggest disadvantages of using larger objectives is the way the scope has to be mounted on the gun. The scope has to be mounted higher thereby making the line of sight higher which in turn makes the sighting process more difficlut than it needs to be. The gun can also become top heavy and lose its natural balance.
there is a solution to this mounting problem as seen with the Leupold Low Mount Scope below. The scope housing has been shaped so that it moulds to the gun therefore reducing the overall height of the scope above the gun.
Another feature found on some scopes is the adjustable objective. This allows better focus at varied ranges, and requires adjustment depending on how far your target is from your scope. I believe this feature does help make some lower-priced variable scopes more dependable as far as point-of-impact goes, but again it usually means that a higher mount is required.
Adjustable objectives are mainly only valuable for long-distance and/or precision shooting, neither of which is required for most hunting situations. Again, your personal requirements come into play here when making your choice.
In closing, let me wish you luck in your search for the perfect scope. If you find it, please let me know – because I have never found the perfect scope, just as I have never found the perfect gun, woman, (sorry dear) etc. But with a little luck and some useful knowledge, you can find a scope that will do a good job for you, whether you are hunting whitetails in close cover or taking pronghorn antelope in the wide-open spaces – or simply punching paper targets in quest of the ultimate one-ragged-hole group.
