Dimpling a barrel

[Evil Bert]

There is one picture missing. One with barrel that is not dimpled but has some weight like dimpled. Because dimpled or fluted barrel are expected to be stiffer and more accurate that plain barrels of same length and mass, not same length and diameter.

okay that makes sense. But I think the pics were a little deceiving to say the least. But good pics none the less. This thread has been very informative.
