I'm trying to decide which one of these I want to get. There doesn't appear to be that many people shooting the 375 compared to the 338 or 300. Is the 375 going to be able to give comparable accuracy out to 500-600 yards? I'm not looking to put a 2 inch group together at that distance. But, if there is ahuge difference between the 338 and 375 I would like to know. thanks.
