When would it be a good idea to use one caliber or the other. 7mm08 micro medallion and a .30-06 m77 are the two rifles I have. I just pick up the ruger in all weather and I really like the way it shoots. The 7 08 is very accurate as well. Which of the two is better for longer shots like big green fields, thick brush, and hardwoods. I love both of my rifles but I can't use but one at a time. Can't wait till opening weekend.
