that is interesting, on ballistics by the inch in 357 mag, it seems 16inch to be the optimal length with all but one ammuntion, i just bought a 20 inch because i figured that would be the highest powered, reckon i figured wrong

can anyone tell why this is the case? seems to be the opposite with rifles, although i rarely have seen ballstics on barrel length over 24in

is it because at the point when all the powder is burnt, then you just have the friction of the barrel causing drag?
