[QUOTE="trebark, post: 825897, member: 19172"] I would agree to go with the 4-12x50 not only because there is little difference between 12x and 14x but there is a big difference in exit pupil. Exit pupil is the size of the image being transmitted to your eye. Calculate exit pupil by dividing the objective size by the maximum magnification. 50/12 = 4.17mm 40/14 = 2.86mm Optimal exit pupil is 5mm. When it comes to shooting at fast moving varmints like coyotes, having a large exit pupil allows you to acquire your target faster. Also, remember scopes do NOT gather light. They transmit it and a larger objective will generally transmit more light than a smaller one. [/QUOTE]
