I like shorter barrels. They feel more handy to me. I do like long barrels for activities like shooting Ground rats just because the added speed helps (some what) with bullet drop.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
