Re: 50mm scope vs 40mm/42mm etc...
[QUOTE=Buano;440629]The larger the objective lens, the more light a scope can let in. Mid-day a large objective lens doesn't help unless using extreme magnification, but a 50mm can give you another 20 minutes of shooting light at dawn & dusk & also helps in crappy weather, where there isn't much light to see by. Assuming the same glass quality, a 50 mm objective lens lets 56% more light through than a 40 mm lens. That's the reason people choose a 50 mm scope.
The quality of the scope makes a large difference. A cheep 50 mm objective scope may not do
as well as a high end 40mm retical scope.
Also the 30mm tubes have an advantage over the 1" tubes because of larger lens internally,
stronger tube because of diameter and a shorter overall scope length. Plus most 30 mm
tube body scopes have a side focus feature and can have more elevation in the turrets.
To me the best all round scope is a 4 to 6 x 14 to 20 x 50mm objective and a 30mm tube
with side focus.
