Just getting ready to rebarrel an rifle to a 6.5. Rifle will be long action with either a 20 or 22" barrel. I do a lot of hunting in thick brush so I want something short. I however want something capable of longer shots if necessary. I dont see ever going over 600yds. Trying to decide between 6.5x55 Swede, 6.5-06, and 6.5-284. Will any of these have an advantage in a shorter barrel?
