[QUOTE="jrock, post: 996524, member: 78569"] Following the "Cantilever beam" theory of a barrel, more mass is required at the breach than the muzzle for increased stiffness. A Palma contour cut to 26" will have a muzzle diameter larger than a #6 contour and weigh less. However, to achieve this, the Palma takes the weight from the breach end where the beam theory says more is needed. I have no idea how a bullet loads a barrel to speculate further. By my estimates, at 26" long, a LP contour is heavier than a #4 and #5. This is the point I'm interested in. [U]What is the design intent for the Palma contours?[/U] I found this interesting read [url=http://www.thehighroad.org/archive/index.php/t-512473.html]Comparison of seven barrel contours in .260 Remington. - THR[/url] [/QUOTE]
