I was wondering about barrel length, and how much barrel is required to achieve maximum potential accuracy. It would seem that there would be a minimum barrel length given a paticular caliber/velocity/bullet weight/bullet length relationship, and any amount of barrel beyond that length would only aid accuracy by increasing the sight radius. Is anyone aware of physics formulas related to this. I am mainly interested in this as related to 44 special and 45 colt handguns, but the idea would obviously affect ideal barrel length on carbine rifles. I would think that with increased barrel length, and the comensurate increase in velocity due to higher percentage of powder burned, the formula would be exponential (perhaps this is not accurate, I'm no physicist). I am also interested in the rifling twist rate formulas. I followed another thread related to this, but I was wondering how this relates to the barrel length issue. Essentially, how much barrel length is required to accomplish maximum bullet stability given the parameters listed above?
