Hey guys so I'm either thinking of getting the leupold vx6hd in 3-18x44 or 3-18x50 with the fire dot duplex and CDS. The 44 mm weighs 16.8 oz and the 50mm weighs 20.4 oz. it will be going on a Browning X Bolt Hells canyon speed in 300 win mag which weighs 6.13 pounds. It will be used for western hunting. Does the 50mm have any advantages/disadvantages to the 44. What are the pros and cons of the 44 and 50mm objective size. Does one gather more light? Any help would be much appreciated thanks
