i've been looking at these 2 scopes pretty heavily to put on my next long range rifle which will be either one of the 7mm mags or 300mags. after reading the specs on the 2 scopes it seems the only real difference is the 44mm has a little bit bigger field of view and an AO. my question is, with the high quality optics found on the 2 scopes is there much advantage in getting the 50mm over the 44mm for light gathering ability? does a 6mm larger objective really make any difference? on a side note, a buddy of mine has the 5.5-16.6,44mm and it worked great in low light situations in wyoming earlier this fall. which one would you get?
