[QUOTE="eddybo, post: 479110, member: 7194"] My buddy has done a great deal of experimenting with this. He would chamber a new barrel and crown it off. Work up the best load he could find them chronograph it. He would then put it back in the lathe part off an inch and recrown and work up a load and chronograph. I do not know how much value his results have on larger cases, but his results showed an average of 17fps per inch in 6PPC for five inches of barrel removed. [/QUOTE]
