I agree that when one looks at the mechcanics of a barrel that a short barrel is as accurate as a long barrel as long as bullet material, velocities, and weights are matched to the bore, rifling, twist, and groove diameter. Changing these things around can make a difference in barrels of the same length. That being said in the real world of people who pay the bulk of taxes and have to work many hours in non shooting jobs, long barrels are more accurate. Nothing beats experience and a well tuned gun and a load made to match. When the 44 Mag. came out in the mid 1950's a 4 inch S&W went on his hip and stayed there every day until he died in 1981. He still kept and used long barreled guns when he felt they were needed. The main thing is to know yourself and your gun and used them for what you practice for. If I was going to spend alot of time shooting at 100 yards and out I would for sure be looking for a 10 inch barrel.
