I like a 28" Barrel with a 1 in 28" Twist. I mostly Hunt with Saboted Bullets and take some Long Shots every now and then. I always thought (and correct me if Im wrong) that a Longer Barrel is more accurate for longer shots as it stbalizes the bullet better for those shots, plus the Longer Barrel also helps all (or most of) the Powder to have a chance to burn and do it's job.
