I'm thinking of getting a new lever action rifle for hunting deer here in the East. Most shots are 100 yards or less and I usually use a 30-30 Winchester. First let me say that I don't really NEED a new rifle, I just want one. My question is is the 45-70 round overkill at this range? I've heard people talk about the round primarily for big game at 50 to 150 yards. My next question is is anyone familiar with the Marlin Guide guns they have an 18 1/2 inch barrel model and a 22 inch barrel model? What is the average effective range for these models? Yes I know it depends on type of round,weather etc, I'm talking a general average accuracy 150 yards, 200 yards, 250 yards? Any ideas?
