I have been reading with interest, although I have had to re-read some parts several times! That comment about John Barsness saying that a smooth barrel increases friction due to more bullet contact really intrigues me. It seems almost counter-intuitive to me. Does anybody know where I can find where he wrote that? Article/book? It would be interesting to see if any other gun loony agrees or disagrees with that theory. (At least I assume it is a theory??) May need to start a new thread on that!

......the occasional hunter wielding a hopelessly inaccurate rifle, living by the fantastical rule that this cartridge can deliver the goods, regardless of shot placement or rifle accuracy. The correct term for this is minute of ego.
