The first component you must be able to depend on to be a "straight shot" is the mass of carbon behind the rifle, the one manipulating what the rifle does.

You also need to be prepared to compromise. The heavy-barreled "long tom" that might seem ideal for a sedate day in the stand over Midwestern whitetails is going to beat your tail if you have to lug it 12 miles a day in hot pursuit of a herd of elk at 8,000-10,000 feet of elevation. Different game require different methods which, in turn, often dictate different equipment.

There's absolutely nothing wrong with a lighter contoured, 20-24" barrel. Most manufacturers offer something in that range, depending on the chambering. Your best bet is to see for yourself, handle them, see what feels right in your hands.
