[QUOTE="longtooth, post: 70129, member: 4039"] The linear expansion of the barrel would be negligible for most purposes.The Thermal Coefficient of Expansion for 416R works out to about 0.00002 per degree starting at 68F/20C (thats the std. reference temp for ISO and ANSI) so a 20 degree increase(88F) would cause the length and dia of the barrel to grow by 0.0004. As to stiffness Varmint AL has a study on that, [url="http://www.varmintal.com/aflut.htm"]www.varmintal.com/aflut.htm[/url] that looks interesting. [/QUOTE]
